The invention relates in general to identification documents and security features for identification documents. In particular, the invention relates to printing covert variable or personal information on identification documents, such that the covert variable or personal information is not identifiable in visible light but is identifiable when viewed in a predetermined non-visible light.
Identification Documents
Identification documents (hereafter “ID documents”) play a critical role in today's society. One example of an ID document is an identification card (“ID card”). ID documents are used on a daily basis—to prove identity, to verify age, to access a secure area, to evidence driving privileges, to cash a check, and so on. Airplane passengers are required to show an ID document during check in, security screening, and prior to boarding their flight. In addition, because we live in an ever-evolving cashless society, ID documents are used to make payments, access an automated teller machine (ATM), debit an account, or make a payment, etc.
Many types of identification cards and documents, such as driving licenses, national or government identification cards, bank cards, credit cards, controlled access cards and smart cards, carry thereon certain items of information which relate to the identity of the bearer. Examples of such information include name, address, birth date, signature and photographic image; the cards or documents may in addition carry other variant data (i.e., data specific to a particular card or document, for example an employee number) and invariant data (i.e., data common to a large number of cards, for example the name of an employer). All of the cards described above will hereinafter be generically referred to as “ID documents”.
Referring to
To protect the information 26a-c that is printed, an additional layer of overlaminate 24 can be coupled to the card blank 25 and printing 26a-c using, for example, 1 mil of overlaminate. The overlaminate 24 can be substantially transparent. Materials suitable for forming such protective layers are known to those skilled in the art of making identification documents and any of the conventional materials may be used provided they have sufficient transparency. Examples of usable materials for overlaminates include biaxially oriented polyester or other optically clear durable plastic film.
In the production of images useful in the field of identification documentation, it may be desirable to embody into a document (such as an ID card, drivers license, passport or the like) data or indicia representative of the document issuer (e.g., an official seal, or the name or mark of a company or educational institution) and data or indicia representative of the document bearer (e.g., a photographic likeness, name or address). Typically, a pattern, logo or other distinctive marking representative of the document issuer will serve as a means of verifying the authenticity, genuineness or valid issuance of the document. A photographic likeness or other data or indicia personal to the bearer will validate the right of access to certain facilities or the prior authorization to engage in commercial transactions and activities.
Identification documents, such as ID cards, having printed background security patterns, designs or logos and identification data personal to the card bearer have been known and are described, for example, in U.S. Pat. No. 3,758,970, issued Sep. 18, 1973 to M. Annenberg; in Great Britain Pat. No. 1,472,581, issued to G. A. O. Gesellschaft Fur Automation Und Organisation mbH, published Mar. 10, 1976; in International Patent Application PCT/GB82/00150, published Nov. 25, 1982 as Publication No. WO 82/04149; in U.S. Pat. No. 4,653,775, issued Mar. 31, 1987 to T. Raphael, et al.; in U.S. Pat. No. 4,738,949, issued Apr. 19, 1988 to G. S. Sethi, et al.; and in U.S. Pat. No. 5,261,987, issued Nov. 16, 1993 to J. W. Luening, et al. All of the aforementioned documents are hereby incorporated by reference.
Printing Information onto ID Documents
The advent of commercial apparatus (printers) for producing dye images by thermal transfer has made relatively commonplace the production of color prints from electronic data acquired by a video camera. In general, this is accomplished by the acquisition of digital image information (electronic signals) representative of the red, green and blue content of an original, using color filters or other known means. Devices such as digital cameras, optical sensors, and scanners also can provide digital image information. The digital image information is utilized to print an image onto a data carrier. For example, information can be printed using a printer having a plurality of small heating elements (e.g., pins) for imagewise heating of each of a series of donor sheets (respectively, carrying diffuseable cyan, magenta and yellow dye). The donor sheets are brought into contact with an image-receiving element (which can, for example, be a substrate) which has a layer for receiving the dyes transferred imagewise from the donor sheets. Thermal dye transfer methods as aforesaid are known and described, for example, in U.S. Pat. No. 4,621,271, issued Nov. 4, 1986 to S. Brownstein and U.S. Pat. No. 5,024,989, issued Jun. 18, 1991 to Y. H. Chiang, et al. Each of these patents is hereby incorporated by reference.
Dye diffusion thermal transfer printing (“D2T2”) and thermal transfer, (also referred to as mass transfer printing) are two printing techniques that have been used to print information on identification cards. For example, D2T2 has been used to print images and pictures, and thermal transfer has been used to print text, bar codes, and single color graphics.
D2T2 is a thermal imaging technology that allows for the production of photographic quality images. In the art, D2T2 has sometimes been referred to as “dye sub”, but D2T2 is not, in fact, really a dye sublimation process. Rather, D2T2 is a diffusion process, and use of the term “D2T2” herein is not intended to include dye sublimation processes. In D2T2 printing, one or more thermally transferable dyes (e.g., cyan, yellow, and magenta) are transferred from a donor, such as a donor dye sheet or a set of panels (or ribbons) that are coated with a dye (e.g., cyan, magenta, yellow, black, etc.) to a receiver sheet (which could, for example, be part of an ID document) by the localized application of heat or pressure, via a stylus or thermal printhead at a discrete point. When the dyes are transferred to the receiver, the dyes diffuse into the sheet (or ID card substrate), where the dyes will chemically be bound to the substrate or, if provided, to a receptor coating. Typically, printing with successive color panels across the document creates an image in or on the document's surface. D2T2 can result in a very high printing quality, especially because the energy applied to the thermal printhead can vary to vary the dye density in the image pixels formed on the receiver, to produce a continuous tone image. D2T2 can have an increased cost as compared to other methods, however, because of the special dyes needed and the cost of D2T2 ribbons. Also, the quality of a D2T2-printed image may depend at least on an ability of a mechanical printer system to accurately spatially register a printing sequence, e.g., yellow, magenta, cyan, and black.).
Another thermal imaging technology is thermal or mass transfer printing. With mass transfer printing, a material to be deposited on a receiver (such as carbon black (referred to by the symbol “K”)) is provided on a mass transfer donor medium. When localized heat is applied to the mass transfer donor medium, a portion (mass) of the material is physically transferred to the receiver, where it sits “on top of” the receiver. For example, mass transfer printing often is used to print text, bar codes, and monochrome images. Resin black mass transfer has been used to print grayscale pictures using a dithered gray scale, although the image can sometimes look coarser than an image produced using D2T2. However, mass transfer printing can sometimes be faster than D2T2, and faster printing can be desirable in some situations.
Printing of black (“K”) can be accomplished using either D2T2 or mass transfer. For example, black monochrome “K” mass transfer ribbons include Kr (which designates a thermal transfer ribbon) and Kd (which designates dye diffusion).
Both D2T2 and thermal ink have been combined in a single ribbon, which is the well-known YMCK (Yellow-Magenta-Cyan-Black) ribbon (the letter “K” is used to designate the color black in the printing industry). Another panel containing a protectant (“P”) or laminate (typically a clear panel) also can be added to the YMCK ribbon)
Many color images are formed by subtractive techniques, e.g., light is passed through absorbing dyes and the combination of dyes produce an image by sequentially subtracting cyan, magenta, and yellow components to provide the full color image. In the example of a UV fluorescing image, the UV image is formed by light emitting from fluorescing dyes or pigments as they are activated by a UV light energy source. In some implementations, a special pigments or dyes used to form a given image can fluoresce in a first color when exposed to light having a first wavelength and a second color when exposed to light having a second wavelength.
A UV image can be imparted to a document such as an ID document by methods such as thermal printing or D2T2 printing, such as with panels on printing ribbons. For example, a separate dye diffusion panel can include dye having UV properties (e.g., but which does not include a visible spectrum color) to impart an UV image to an ID document, or UV materials can be incorporated into an existing color panel (e.g., into the yellow panel). As the invention proposes herein, a UV image can also be imparted via a mass transfer panel (or thermal mass transfer) panel. Standard dye diffusion printers, such as those manufactured by Atlantek and Eltron, often incorporate both dye diffusion and mass transfer panels. A mass transfer panel typically includes a resin (e.g., a resin including black or color pigments or dyes) that can be thermally transferred to the ID document. A separate mass transfer panel can include pigments or dyes having UV properties to impart a UV image to an ID document, or UV materials can be incorporated into a specially constructed black panel, as described herein. A mass transfer process can be used to produce an image, which is invisible in ordinary light, but glows in UV light.
UV Security Features in ID Documents
One response to the ID document counterfeiting problem has involved the integration of verification features that are difficult to copy by hand or by machine. One such verification feature is the use in the card of a signature of the card's issuer or bearer. Other verification features have involved, for example, the use of watermarks, biometric information, microprinting, fluorescent materials, fine line details, validation patterns or marking, and polarizing stripes. These verification features are integrated into an identification card in various ways and they may be visible or invisible (covert) in the finished card. If invisible, they can be detected by viewing the feature under conditions which render it visible. At least some of the verification features discussed above have been employed to help prevent and/or discourage counterfeiting.
Covert security features are those features whose presence is not visible to the user without the use of special tools (e.g., UV or IR lights, digital watermark readers) or knowledge. In many instances, a covert security feature is normally invisible to a user. Some technologies that involve invisible features require the use of specialized equipment, such as a detector or a device capable of reading digital watermarks. One type of covert security feature is the printing of information (images, designs, logos, patterns, text, etc.) in a material that is not visible under normal lighting conditions, but can be viewed using a special non-visible light source, such as an ultraviolet (UV) or infrared (IR) light source. Use of UV and/or IR security features can be advantageous because although the devices (for example, UV and/or IR light sources) required to see and use such features are commonly available at a reasonable cost, the ability to manufacture and/or copy at least some implementations of such features is far less common and can be very costly. UV and IR based covert security features thus can help deter counterfeiters because the features cannot be copied by copiers or scanners and are extremely difficult to manufacture without the requisite know-how, equipment, and materials.
For example, the assignee of the present invention has developed and marketed a proprietary product called PolaPrime-UV™. PolaPrime-UV™ is a type of security feature One application of PolaPrime-UV™ is for full color photo quality printing of fixed (i.e., not variable data) fluorescent images. The artwork that can be printed using PolaPrime-UV™ includes many images that can be produced with a combination of red, green, and blue phosphors. Under the appropriate light (e.g., a light source capable of providing UV light), the effect seen when viewing an image printed with PolaPrime-UV™ is similar in appearance to a television screen in that the image is formed by emission of light rather than reflection as with ink on paper. To date, PolaPrime-UV™ has been a reliable authenticator for genuine identification documents. Because PolaPrime-UV™ is a fixed process and has no variable capability, PolaPrime-UV™ has only been used for pre-printed or non-variable data, not personalized or variable full color images.
To date, there have been no examples of printing variable images such as driver's license portraits with UV or IR materials, where the quality of the UV variable image is sufficient to enable the image to be relied upon for identification or authentication.
Because of the enhanced security provided by the use of full color UV printing, it would be advantageous to be able to print variable or personal UV information at the time of card personalization, in one, two, or three UV colors, especially images that have a high enough quality to be used for authentication and/or identification. It also would be advantageous if the same information could be printed in a visible and invisible (e.g., UV) form at substantially the same time or at substantially the same printing step. It would be an advantageous security feature and counterfeit deterrent if, in at least some instances, the visible and invisible information could be printed to appear on the same location of the ID document.
In one aspect, the present invention provides improved ID documents that include printing variable data (e.g., text, personal information, biometric data, etc.) or security features (e.g., images, photographs, codes, digital watermarks, etc.) that are imperceptible to the human eye. When illuminated with UR (or IR) light, however, the variable data or security features become readily visible. The quality of the images produced is such that they are usable for identification and/or authentication.
In another aspect, for at least the printing of UV information that comprises characters or single color images (e.g., simple logos or graphics), the inventors have discovered that using a thermal transfer approach to print full color UV images can overcome at least some of the problems that can be seen when printing UV information using D2T2 printing. In one embodiment, thermally diffusible UV dyes are used with a mass transfer medium, resulting in a UV image that is disposed both on top of and into the medium to which the UV image is printed. Having an image that is formed both on top of and into a medium can increase the security of the image that was printed, because even if the portion of the image that is on “top” of the medium is removed (e.g., in an attempt at alteration), the portion of the image that is disposed “into” the medium remains.
In one embodiment, an identification document is provided comprising first and second layers. The first layer has a first layer a first colored variable indicium formed thereon that is visible to the human eye as a substantially full color image when the first colored variable indicium is viewed using a first type of light. The second layer is operably coupled to the first layer and has a second colored variable indicium that is visible to the human eye as having the appearance of a substantially full color image when the second colored variable indicium is viewed using a second type of light. The second colored variable indicium can be printed using a thermally diffuseable non visible dye disposed in a resin panel on a thermal transfer printing ribbon.
In another aspect, the invention provides a method for printing a UV image at the same time that it prints a full color image. The UV dye is selected so to be a thermally diffusible UV fluorescent dye that diffuses with substantially the same properties as the visible dyes on the panel.
In a further aspect, the image to be printed in UV is digitally manipulated so that a UV image is printed on an identification document using only two of the three colors, printing a so-called “false two color” UV image. In one embodiment, the two colors comprise yellow and at least one of cyan and magenta. The “false two color” UV image is printed using UV dyes. We have found that one, two or three UV colors, as well as false two color, images printed in accordance with the invention can be of “identification quality” (i.e., good enough discernibility enough to be used for identification purposes).
In one embodiment, a method for manufacturing an identification document is provided. A substrate is provided that is constructed and arranged to receive printing thereon. A first variable indicium is printed on the substrate, where the first variable indicium is not visible to the human eye in ambient light but is visible to the human eye when viewed using a first type of light.
In one embodiment, the invention provides a method for manufacturing an identification document. A substrate is provided that is constructed and arranged to receive thermal transfer printing thereon. A first variable indicium is printed on the substrate using a thermal transfer ribbon, the thermal transfer ribbon comprising at least one panel, the panel comprising a thermally diffuseable dye dissolved in a resin, where the dye comprises at least one component that is not visible to the human eye in ambient light.

Terminology
In the foregoing discussion, the use of the word “ID document” is broadly defined and intended to include all types of ID documents, including (but not limited to), documents, magnetic disks, credit cards, bank cards, phone cards, stored value cards, prepaid cards, smart cards (e.g., cards that include one more semiconductor chips, such as memory devices, microprocessors, and microcontrollers), contact cards, contactless cards, proximity cards (e.g., radio frequency (RFID) cards), passports, driver's licenses, network access cards, employee badges, debit cards, security cards, visas, immigration documentation, national ID cards, citizenship cards, social security cards, security badges, certificates, identification cards or documents, voter registration and/or identification cards, police ID cards, border crossing cards, security clearance badges and cards, legal instruments, gun permits, badges, gift certificates or cards, membership cards or badges, and tags. Also, the terms “document,” “card,” “badge” and “documentation” are used interchangeably throughout this patent application.). In at least some aspects of the invention, ID document can include any item of value (e.g., currency, bank notes, and checks) where authenticity of the item is important and/or where counterfeiting or fraud is an issue.
In addition, in the foregoing discussion, “identification” at least refers to the use of an ID document to provide identification and/or authentication of a user and/or the ID document itself. For example, in a conventional driver's license, one or more portrait images on the card are intended to show a likeness of the authorized holder of the card. For purposes of identification, at least one portrait on the card preferably shows an “identification quality” likeness of the holder such that someone viewing the card can determine with reasonable confidence whether the holder of the card actually is the person whose image is on the card. “Identification quality” images, in at least one embodiment of the invention, include covert images that, when viewed using the proper facilitator (e.g., an appropriate light source), provide a discernable image that is usable for identification or authentication purposes.
There are a number of reasons why an image or information on an ID document might not qualify as an “identification quality” image. Images that are not “identification quality” may be too faint, blurry, coarse, small, etc., to be able to be discernable enough to serve an identification purpose. An image that might not be sufficient as an “identification quality” image, at least in some environments, could, for example, be an image that consists of a mere silhouette of a person, or an outline that does not reveal what might be considered essential identification essential (e.g. hair or eye color) of an individual.
Of course, it is appreciated that certain images may be considered to be “identification quality” if the images are machine readable or recognizable, even if such images do not appear to be “identification quality” to a human eye, whether or not the human eye is assisted by a particular piece of equipment, such as a special light source. For example, in at least one embodiment of the invention, an image or data on an ID document can be considered to be “identification quality” if it has embedded in it machine-readable information (such as digital watermarks) that also facilitate identification and/or authentication.
Further, in at least some embodiments, “identification” and “authentication” are intended to include (in addition to the conventional meanings of these words), functions such as recognition, information, decoration, and any other purpose for which an indicia can be placed upon an article in the article's raw, partially prepared, or final state. Also, instead of ID documents, the inventive techniques can be employed with product tags, product packaging, business cards, bags, charts, maps, labels, etc., etc., particularly those items including marking of an laminate or over-laminate structure. The term ID document thus is broadly defined herein to include these tags, labels, packaging, cards, etc.
“Personalization”, “Personalized data” and “variable” data are used interchangeably herein, and refer at least to data, images, and information that are “personal to” or “specific to” a specific cardholder or group of cardholders. Personalized data can include data that is unique to a specific cardholder (such as biometric information, image information, serial numbers, Social Security Numbers, privileges a cardholder may have, etc.), but is not limited to unique data. Personalized data can include some data, such as birthdate, height, weight, eye color, address, etc., that are personal to a specific cardholder but not necessarily unique to that cardholder (for example, other cardholders might share the same personal data, such as birthdate). In at least some embodiments of the invention, personal/variable data can include some fixed data, as well. For example, in at least some embodiments, personalized data refers to any data that is not pre-printed onto an ID document in advance, so such personalized data can include both data that is cardholder-specific and data that is common to many cardholders. Variable data can, for example, be printed on an information-bearing layer of the ID card using thermal printing ribbons and thermal printheads.
As used herein, the term “fixed data” refers at least to data which is identical for each ID card. Fixed data can, for example, be preprinted on an overlay patch, a laminate or an information-bearing layer of the ID card. Fixed data can also be printed on each individual ID card during the process of printing and optionally laminating the ID card. The term “variable data” refers generally to data which differs for each ID card and is associated with personal information, an image of the ID card holder or a unique reference number for security purposes assigned by the issuing agency.
As used herein, an “information-bearing layer” refers at least to the parts of an ID document where pictures, images, text, bar codes, fixed and/or variable data are printed. The information-bearing layer can include a separate receiver layer adapted to accept inks, dyes, pigments and resins from thermal print ribbons. The information-bearing layer can itself be the receiver layer. Depending on the particular design of the ID document, the information bearing layer can be the substrate or core layer, but also can be a laminate applied thereto, or to another laminate layer on the card. There can be different information bearing layers in an ID document for pre-printing and for personalization.
“Laminate” and “overlaminate” include (but are not limited to) film and sheet products. Laminates usable with at least some embodiments of the invention include those which contain substantially transparent polymers and/or substantially transparent adhesives, or which have substantially transparent polymers and/or substantially transparent adhesives as a part of their structure, e.g., as an extruded feature. Examples of potentially usable laminates include at least polyester, polycarbonate, polystyrene, cellulose ester, polyolefin, polysulfone, polyvinyl chloride (PVC), polyethylene, polypropylene, and polyamide. Laminates can be made using either an amorphous or biaxially oriented polymer as well. The laminate can comprise a plurality of separate laminate layers, for example a boundary layer and/or a film layer. Other possibly usable laminates include security laminates, such as a transparent laminate material with proprietary security technology features and processes, which protects documents of value from counterfeiting, data alteration, photo substitution, duplication (including color photocopying), and simulation by use of materials and technologies that are commonly available. Laminates also can include thermosetting materials, such as epoxy. Laminates can include synthetic resin-impregnated or coated base materials composed of successive layers of material, bonded together via heat, pressure, and/or adhesive.
The material(s) from which a laminate is made may be transparent, but need not be. The degree of transparency of the laminate can, for example, be dictated by the information contained within the identification document, the particular colors and/or security features used, etc. The thickness of the laminate layers is not critical, although in some embodiments it may be preferred that the thickness of a laminate layer be about 1-20 mils. Lamination of any laminate layer(s) to any other layer of material (e.g., a core layer) can be accomplished using any conventional lamination process, and such processes are well known to those skilled in the production of articles such as identification documents. Of course, the types and structures of the laminates described herein are provided only by way of example, those skilled in the art will appreciated that many different types of laminates are usable in accordance with the invention. Various lamination processes are disclosed in assignee's U.S. Pat. Nos. 5,783,024, 6,007,660, 6,066,594, and 6,159,327. Other lamination processes are disclosed, e.g., in U.S. Pat. Nos. 6,283,188 and 6,003,581. Each of these U.S. Patents is herein incorporated by reference.
For purposes of illustration, the following description will proceed with reference to ID document structures (such as TESLIN-core, multi-layered ID documents) and fused polycarbonate structures. It should be appreciated, however, that the present invention is not so limited. Indeed, as those skilled in the art will appreciate, the inventive techniques can be applied to many other structures formed in many different ways to provide information thereon that is not identifiable and generally not visible using visible light, but which is visible or identifiable when using a non-visible light, such as an ultraviolet (UV) light or an infrared (IR) light. In another aspect, the invention also has applicability to providing information on structures that fluoresce in a given spectrum (e.g., the UV or IR spectrum) upon excitation with visible light. Generally, the invention has applicability for virtually any product which is to be printed and especially those products which need to be uniquely identified and/or protected against fraud and/or tampering. For example, at least some embodiments of the invention are usable to form non visible indicia on articles formed from paper, wood, cardboard, paperboard, glass, metal, plastic, fabric, ceramic, rubber, along with many man-made materials, such as microporous materials, single phase materials, two phase materials, coated paper, synthetic paper (e.g., TYVEC, manufactured by Dupont Corp of Wilmington, Del.), foamed polypropylene film (including calcium carbonate foamed polypropylene film), plastic, polyolefin, polyester, polyethylenetelphthalate (PET), PET-G, PET-F, and polyvinyl chloride (PVC), and combinations thereof.
In addition, for purposes of illustration, the following detailed description is provided using ultraviolet (UV) information as an example of a type of information that is generally not visible using normal light but is visible using an appropriate light source (e.g., a UV light source). It should be understood that while some of our detailed embodiments described herein use UV dyes, inks, light source, ribbon panels, etc., by way of example, the present invention is not so limited. Our inventive techniques and methods can be used in connection with infrared and other fluorescing images as well. Accordingly, those skilled in the art will appreciate that each and every reference to UV inks, dyes, light sources, panels, on ribbons, etc., is equally applicable to other types of information that is generally not visible using normal light, such as infrared (IR) information, as well as to information printed using a blend of UV and IR fluorescing compounds. Moreover, one or more of our inventive techniques can be useful in the printing of images destined for ID documents using various printing processes including, but not limited to, dye infusion, mass-transfer, laser xerography, ink jet, wax transfer, variable dot transfer, and other printing methods by which a fluorescing image can be formed.
Further, it should be appreciated that although the some of the figures illustrate a particular species of ID document—a driver's license—the present invention is not so limited. Indeed our inventive methods and techniques apply generally to all identification documents defined above. Moreover, as noted herein, our invention is applicable to non-ID documents, e.g., such as printing or forming non-visible images on physical objects, holograms, etc., etc.
It is further anticipated that the invention could have applicability in manufacturing articles which are to have a feature formed thereon (especially a feature that is intended to have the appearance of an identifiable full color feature) that is not necessarily intended to be used as a security or identification feature, but which is at least intended to be non visible to a human eye in visible light, but visible using a non-visible light such as UV or IR, or which is intended to glow or fluoresce in a non-visible spectrum upon excitation with visible light. It is anticipated that the one or more embodiments of the invention can have applicability in industries such as aerospace, defense, the military, pharmaceuticals, consumer goods, medicine and medical devices, electronics, publishing, advertising, promotion, entertainment, the production of artwork, signage, decorative items, and novelty products.
Application of the Invention to ID Documents
In one aspect, the invention provides ID documents having full-color UV “identification quality” variable information printed thereon at the time the ID document is personalized. The variable UV information is not visible in normal (e.g., ambient) light, but is visible when viewed using a non-visible light source, such as a UV light source.
The inventors of the instant application have discovered at least one reason why, until now, it has been is difficult to obtain “identification quality” full color images UV images when printing variable data in UV on an ID document such as an ID card. Recall that humans see visible images when light is shined on them and the light reflecting back creates an image visible to a human eye—a net subtractive technology. When humans (using an appropriate light source) see UV (or IR) images, however, what the human eye sees is not a reflection, but rather an emission—humans see the light that is emitted because the compounds used to form the image fluoresce when viewed using the appropriate [UV or IR] light source.
When non-visible variable information is printed on ID documents that already have pre-printed information thereon, however, the reflections of the preprinted information can interfere with the light emitting from fluorescing dyes or pigments as they are activated by an appropriate light or energy source. This interference can result in diminished quality of the non-visible image. In addition, some of the emissions from the fluorescing dyes or pigments can be absorbed back into parts of the ID document, including back into dyes that might be on the ID document. The reflections from the pre-printed information do not always affect the ability to discern some types of information (such as characters and simple graphics) printed with non-visible inks/dyes, but the reflections can make an image such as a portrait virtually unusable as an “identification quality” image. We have found that to help achieve the best quality colored UV images, it is necessary during printing and selection of the printing ribbon to take into account the reflections of pre-printed information that still occur when UV information is viewed using a UV light source. We have found that the existence of these reflections can limit the physical locations on an ID document where one can form an “identification quality” UV image using D2T2 type printing. For printing UV using D2T2, we have found that it often is necessary to have a substantially “pristine” card area (an area where there are no reflections already present from other image) in which to print a D2T2 image.
Another problem associated with printing some types of non-visible images, such as UV images, is that since the non-visible image “glows” under appropriate UV stimulation, image details are less apparent, blurred or can be completely lost. The UV glowing essentially washes out an image's perceptible crispness (e.g., similar to a situation in which a dimly lighted object is in proximity to a brightly lighted object). The following commonly assigned pending provisional patent applications provide some methods for addressing this problem:
We have found that use of the techniques and methods recited in the above applications (which we explain at a high level below) can, in combination with the techniques described herein, improve the quality of variable information printed in full color UV. In at least some embodiments, the above-cited provisional applications provide ways to enhance image details to overcome the UV washout problem. In at least some embodiments, the above-cited provisional applications disclose ways to digitally process an image prior to printing to compensate for the glowing effect.
First Aspect of the Invention
In a first aspect of the invention, we provide an ID document and method for making the ID document, where the ID document has thereon a discernable, identifying variable data image that is visible only under UV illumination. In one embodiment of the first aspect, this discernable identifying variable data image (which we call a “UV Ghost Image”) is provided on the card in addition to a visible image (which can, for example, be the same image) printed on the card. For example,

Note that although the UV Ghost image 112 is shown as being smaller in size and in a different place than the visible bearer image 122, the invention is not limited to this implementation. It at least one embodiment, for example, the location of the UV Ghost image 112 can coincide with the respective location of the corresponding visible information (in which case, the appearance of the ID document 100 under UV light could look very similar to the way it looks in visible light in
In
In one implementation of this embodiment, the UV ghost image 112 is formed with a dye panel that contains a UV fluorescing dye. The UV dye panel is used as an additional panel to the CMY panels in a conventional D2T2 ribbon. For example,
In accordance with this embodiment of the invention, the UV ghost image 112 of
In one embodiment, another technique that we have found to compensate for the UV emission absorption problem is to use a detector device when viewing the information under UV light. The detector is used to amplify the received light signals to compensate for the emission absorption problem, and can recreate information in one, two, or three colors based on UV information that it detects. A detector usable in this embodiment can be obtained from Assuretec Systems, Inc. of Manchester, N.H.
In another embodiment, the UV ghost image 116 can be printed as a three color image with a specialized ribbon.
Image Processing Techniques for Printing Variable UV Information on Identification Documents
In still another embodiment of the first aspect, to help create a discernable fluorescing image on an ID document (useful for identification and security checks) we have found that we can enhance the digital data that is used to create the UV image. Enhancing the digital data as described herein can help to overcome possible “washout” problems that can occur when a UV image is fluoresced. These enhancements (which are also detailed in the following commonly assigned pending provisional patent applications) provide some methods for addressing the UV washout:
We have found that different image processing techniques are preferred used to preprocess an original image depending on whether the tonality of image reproduction (e.g., printing process) is bitonal (e.g., two tones such as black and white or a first color and second color) or monochromatic (e.g., shaded image, grayscale, etc.). (We also note that other optional factors to consider include the viewing methods used with the image, such as reflectance, transmissive characteristics (e.g., as discussed above with the UV glowing) and tactility.
For the methods discussed below, we assume that an image has been digitally captured, e.g., via a digital camera, optical sensor, etc., or through scanning a photograph with a scanner, etc. This captured image can be reprinted on the identification document as visible bearer image 122 in
Mass Transfer Images
Our first inventive method is particularly well suited for producing bitonal images (e.g., black and white images), such as produced through mass-transfer thermal printing and Laser Xerography. Generally, we process a captured image to bring-out or otherwise enhance relevant features found in the captured image. Relevant features of a human face may include the face outline, nose and mouth pattern, ear outline, eye shape, hairline and shape, etc. Once identified, these featured can be “thickened” or otherwise emphasized. The emphasized features can then form a digital version of UV ghost image 112, which can be transferred to an identification document.
The following discussion proceeds with reference to the accompanying flow diagrams and images (
Now, consider a specific implementation with reference to
We analyze the contrast-enhanced image to identify or detect edges and/or boundaries within the image in step 524. As noted, eyes, nose and mouth often include prominent edges. Our preferred edge detection algorithm is the Sobel algorithm, however, we note that many other conventional algorithms such as other gradient-based edge detection algorithms (e.g., Roberts, Prewitt), Laplacian (e.g., Morrs-Hildreth) and the Canny edge algorithm can be suitably interchanged with this aspect of the present invention. The results of an edge detector produce an outline-like image, which highlights the edges (or maybe just the significant edges) of the monochromatic image. If using a Sobel algorithm, or another algorithm that produces multiple planes, a horizontal edge plane (
The composite image is then smeared, thickened or otherwise emphasized in step 528 (
In some implementations, this thickened image (
We have found that our method significantly reduce the washing-out of image details experienced in conventional UV images (when fluorescing).
An alternative implementation is discussed with reference to

With reference to
Second Aspect of the Invention
In a second aspect of the invention, we provide an ID document and method for making the ID document, where the ID document 100 that is provided that includes variable data (e.g., text, personal information, biometric data, etc.) that is imperceptible to the naked human eye. When illuminated with UV (or IR) light, however, the variable data or security features become readily visible. For example, with reference to
In one implementation of this aspect, at least one character and/or bar code based variable data (e.g., name, date of birth, address, tracking number, sequence number, and the like) that is printed in visible text on an ID document also is printed on the ID document in UV inks, such as by a specific panel on a D2T2 ribbon. In one embodiment, the specific panel on the D2T2 ribbon is a “resin transfer” panel, (not unlike the a K panel that is conventionally used for visible text and bar codes), where the resin transfer panel further comprises UV fluorescing dyes or pigments, the desired color(s) for printing UV characters.
In at least one embodiment of this aspect, after the UV text is applied to the ID document substrate using the D2T2 UV resin transfer ribbon 172, a laminate (such as a polyethylene terephthalate (PET)) based laminate) can be applied over the UV text. Application of this laminate can cause the UV text to fracture (split apart) upon an intrusion (e.g., counterfeiter or forger) attempt. The laminate is selected such that its adhesive strength is greater than its cohesive strength, whereby the laminate splits apart during attempted intrusions. As those skilled in the art will appreciate, the application of the laminate over the UV text can be controlled and adapted so that as the laminate splits, at least part of the UV text remains in one portion of the laminate and at least part of the UV text is on the other split portion of the laminate.
Although the variable UV character data 110 is shown in
Third Aspect of the Invention
In a third aspect of the invention, we provide an ID document and method for making the ID document, where the ID document has thereon a discernable, identifying variable data image that “glows” when illuminated by UV light. In one embodiment of the first aspect, this discernable identifying variable data image is provided on the card in addition to a visible image (which can, for example, be the same image) printed on the card. For example,
In one implementation of this aspect, variable data is D2T2 printed with a special ribbon that contains the usual visible Cyan (C), Magenta (M) and Yellow (Y) panels, but where at least one of the visible panels also contains a corresponding a heat diffuseable UV fluorescing dye. The heat diffuseable UV fluorescing dye can be the same color as the visible panel that is diffused into the ID document substantially simultaneously with the visible panel, but it need not be the same color. In fact in at least one embodiment, it is preferred that the color of the heat diffuseable UV fluorescing dye be different than the color of the panel, to enable the color of the UV to be viewed more clearly under UV light.
In this implementation, the UV image that glows in necessarily coincides exactly with the corresponding visible image (as can be seen in
Of course, instead of D2T2, other printing techniques can be used so long as UV dyes or inks are transferred to the substrate, to represent a particular color. Additional UV panels can be added to achieve additional ghost image colors. In other implementations of the invention, the UV component can be mixed with process colors CM or Y, and applied using conventional printing techniques.
This aspect of the invention also can provide forensic advantages. Because the design of the UV glowing ribbon 180 links the dye that makes the visible image to the dye that makes the fluorescent image, it can be extremely difficult to duplicate a pair of visible-UV dyes on and ID document. Thus, the use of a fraudulent dye for either the UV or the color or both can help to serve as a “fingerprint” in detecting the origin and type of fraud.
Fourth Aspect of the Invention
It generally has been difficult to have information such as black text and/or black bar codes be able to be printed with UV colorant (dyes/inks) such that the black text/bar codes can glow, because the black text/bar codes tend to absorb much of the emitted light. To help overcome at least some of this problem, in a fourth aspect of the invention, we provide an ID document and method for making the ID document, where at least some of the variable black text on the document glows in one or more of a number of available colors under UV illumination. In one embodiment, the black text is printed by a conventional K (black) panel, such as a resin transfer panel with carbon black for optical density. The ribbon containing the K panel, however, is constructed to include an optically clear layer containing an UV fluorescing dye or pigment.
A cross sectional view of the UV on black ribbon 190 is illustrated in
In at least one embodiment, the UV resin in the optically clear layer and the resin in the carbon black layer 170 of the UV on black ribbon 190 are compatible (i.e., miscible in all proportions). Compatibility between the resin in both the clear layer and the resin in the carbon black layer can help ensure intimate bonding upon a coating operation. One way to ensure that the UV resin and the carbon black resin are compatible is to prepare each resin using the same resin binder (e.g., polyvinyl chloride (PVC), acrylate, urethane, etc., and the same solvents (e.g. polyvinyl buterol, methyl ethyl ketone, toluene, toluol, etc.). Selection of the appropriate solvents and resins to work with UV and carbon black is, of course, within the skills of those familiar with the art.
Fifth Aspect of the Invention
In a fifth aspect of the invention, we provide an ID document and method for making the ID document, where the ID document has a full color UV variable image formed thereon and the full color variable UV image is printed on the ID document using a thermal transfer method. The appearance of the resultant full color UV image in this aspect can be similar to that of the full color UV images discussed in connection with the first aspect of the invention; further, all of the special digital processing of the image discussed in connection with the first aspect is similarly applicable here. However, this fifth aspect of the invention differs from the first aspect in that in this aspect prints the full color UV image via thermal transfer. This fifth aspect of the invention can be particularly advantageous for speeding the manufacture of ID documents such as driver's licenses and other photo ID cards, because thermal transfer printing tends to be quicker than D2T2 printing. In addition, this fifth aspect can of course be used to print variable image data on an ID document
To print the full color UV image on an ID document, we have developed a full color UV thermal ribbon 204, as illustrated in
Note also that, in at least one embodiment of the invention, the Z panel comprises two colored UV sub panels and is capable of producing a so-called “false two color image”, in the manner described below.
Each colored UV sub panel 208, 210, 212 comprises thermally diffuseable UV dyes dissolved in a resin. Use of thermally diffuseable UV dyes in a resin used in a conventional thermal/mass transfer ribbon improves the printing and security of a UV image formed on a substrate because the resultant image is formed both on top of and into the substrate. This is illustrated more particularly in
Security of the full color UV image printed on the card is increased as compared to known methods, because the full color UV image that is printed is actually present in two places: in the PVC 22 and on top of the PVC 22. Attempts to fraudulently alter and ID document printed in this manner can be thwarted by the fact that even if the over laminate 24 is removed, a detectable amount of full color UV printing remains within the laminate 22.
In at least one embodiment, it is preferred that the full color UV image printed using the Z panel be printed with a resolution of at least 600 dots per inch (dpi), to provide a photo quality image for identification purposes. For a 600 dpi resolution, the full color UV thermal ribbon 204 and the thermal print head (not shown, but substantially similar to the thermal print head of
In another embodiment, it is preferred that the full color UV image printed using the Z panel be printed with a resolution of at least 300 dots per inch (dpi). For a 300 dpi resolution, the full color UV thermal ribbon 204 and the thermal print head are constructed and arranged to operate to print at least 4-6 levels of color in a given pixel.
One way to achieve multiple color levels of color is through the use of so-called megapixels. A megapixel is created by dividing a given pixel into a plurality of sub-pixels, such that (using a square pixel, for example) an n-by-n megapixel is formed. Thus, instead of a given pixel being “on” or “off”, a given pixel can have 5 different levels of shading. This is illustrated for the example 2 by 2 megapixel of
Sixth Aspect of the Invention
In this aspect of the invention, any of the embodiments provided in the first through fifth aspects described above can also be utilized where the UV fluorescing compounds/colorants/inks/dyes are replaced with an IR fluorescing compounds/colorants/inks/dyes. These IR dyes then react when illuminated with IR light. Those skilled in the art will readily perceive how to adapt the first through fifth aspects of the invention for use with IR.
Seventh Aspect of the Invention
In this aspect of the invention, a blend of UV and IR compounds/colorants/inks/dyes can be used to further increase card security. As an example, for multiple invisible colors used on a given card, one color is seen under UV illumination and another color is seen in IR illumination. An example of this is shown in
In at least one embodiment of this aspect, the UV and IR components can be part of the same ribbon and printed to the ID document at the same time, using either D2T2 or mass transfer printing. The combination of UV and IR also can be printed to the same image. So, for example, a given image (e.g., a portrait on an ID card) could be printed entirely in a yellow UV color and entirely in a magenta IR color. These UV and UR images can be wholly or partially superimposed, or positioned on entirely separate parts of the ID document. Thus, a given image could show a yellow color when viewed using a UV light source and, either in the same location or a different location, a magenta version of the image can be visible when viewed using and IR source. And, neither image will be viewable using only visible light (although either or both of the UV and IR could be superimposed, wholly or partially, on one or more visible images).
Many combinations are possible in this aspect of the invention. In one combination, the photograph is augmented with UV dyes, while the text is augmented with IR dyes, or vice versa. In another combination, a “ghost image” is seen under IR illumination, while other features are visible with UV illumination: Those skilled in the art will appreciate that many implementations of this aspect are possible
One of ordinary skill in the art will appreciate that information than the types of information described herein could be similarly provided on any ID document. Similarly, one of ordinary skill in the art will appreciate, in light of the teachings provided herein, that some of the information could be printed using a reverse format.
