The present invention relates generally to associating printing information with print media. More particularly, printing information can be associated with print media that is related to properties of the print media and/or properties of an image applied to the print media.
Many conventional printing operations utilize print media with varying printing characteristics. For example, common print media used in connection with ink-jet printers include: standard office paper for general print jobs; photographic-quality print media for printing digital photographs; and colored or decorated media for printing greeting cards, brochures, invitations, etc. Due to the various types of print media, and the various type of ink being applied to the print media, printers often use varied settings when printing to ensure the best image is produced on the print media. That is, the printer setting can be varied in order to optimize the printing process for the particular print medium being used.
As an example, photo-quality print media may absorb more or less ink than more conventional papers, depending on the characteristics of the photo print media. Many printers have been configured to account for this fact and include interface software to enable the user to indicate to the printer which print media is being utilized. While this provides a user with the option of tailoring the printing process to the print media being used, the user must typically ensure that the printer is provided with the proper identification of the print media being used. This can be further complicated when a variety of print media are being used, as such information must provided to the printer with each print job sent in order to achieve the best results.
Some printers have been developed that include optical sensors which detect light reflection properties of print media in an effort to determine the type of print media being utilized. Print media detectors have also been used which detect a level of elasticity present in print media in an effort to determine the weight and other properties of the print media. However, these methods have proved problematic in that the detection system being used must rely on detectable qualities of the print media, which can lead to errors in proper detection of print media, particularly since there are many different types of print media from many different companies. Also, print media may vary in characteristics other than those detectable by such methods, such as fiber composition and length, etc.
In addition to these problems associated with variable print media, digital images have for some time been printed on or applied to print media. For example, many consumers own digital cameras and make a practice of storing the images captured by the digital camera in digital files on a home computer. Other consumers scan traditional photos into digital files and store the digital files on a home computer. Once stored on the computer as a digital file, consumers can print hard copies of those images as described. While this process enables the consumer to obtain a printed hard copy of the image desired, the resulting hard copy suffers from problems long associated with traditional photography. For example, only the image is transferred to the print media and the print media generally contains no extraneous information relating to the image.
Consequently, if the consumer wishes to re-print the image in the future, the consumer must locate the particular digital file containing the image (much like the case in traditional photography, wherein a consumer would have to locate the negative from which an image was developed onto photographic paper). Because a user may have many digital image files stored on the computer, it may be difficult to locate the original digital image file. In addition, in the case where a user prints an image located on a distant server, for instance on the internet, a user may not remember which site contained the image file if he or she wishes to view the image file again. Further, users who print hard copies of digital images often edit the image or apply special filters, red-eye tools, etc., prior to printing the image. A user may be particularly pleased with the resulting hard copy of the image, but when attempting to re-create the same effect may have difficulty remembering which filters were applied or which editing techniques were used prior to transferring the image onto the print medium.
It has been recognized that it would be advantageous to provide a method and device that can be used to accurately identify print information related to a print medium and/or an image applied to the print medium. Specifically, it has been recognized that it would be advantageous to provide a print medium having a data storage device attached thereto to receive and store printing information. The print medium can be configured to receive a printed image, and the data storage device can be configured to receive and store printing information.
In accordance with another aspect of the invention, a printing system can include a print medium configured to receive a printed image, and a data storage device attached to the print medium. The data storage device can be configured to receive and store printing information. A printer is also provide and can be configured to print the image on the print medium. A printing information processor can be associated with the printer and can be configured to read data from and write data to the data storage device.
In accordance with another aspect of the invention, a method for associating printing information with a print medium is provided, and includes the steps of attaching a data storage device to the print medium, and storing printing information on the data storage device.

As illustrated in
By advantageously providing a data storage device 14 attached to a print medium 12, the present invention can be utilized to maintain print information integrally with the print medium. When used with a printer having a printing information data processor, as discussed in further detail below, the printer can read information stored on the data storage device to automatically detect properties of the print medium, obviating the need for a user to indicate to the printer which print medium is being used. In addition, by storing information relating to an image applied to the print medium, the image information can be maintained integrally with the printed image to enable a user to access the image information at a later date.
The type of information storable upon the data storage device 14 can be of a variety that would be known to those in the art after considering the present disclosure. For example, information or data relating to the print medium 12 can be stored on the storage device. Such print media data can include, without limitation, size and weight of the print medium, quality or finish of the print medium, or ink capacity of the print medium. Also, data such as which default printing mode should be associated with the print medium, i.e., best quality or draft quality, can be stored on the data device, as well as information relating to a preferred color map to be used with the print medium.
In addition to information relating to the properties of the print medium 12, operational data files usable by the printer can be stored on the data storage device 14. For example, a file containing computer code defining a color map can be stored on the data storage device. In addition, printer drivers optimized for the print medium can be stored on the storage device and used by the computer and printer. This can be advantageous in that manufacturers of print media can include updated printer drives for particular printers to optimize the printing process on newly developed print media.
In one aspect of the invention, information relating to an image applied, or to be applied, to the print medium 12 can be stored on the data storage device 14. Information relating to the image can include, without limitation, “pointer” information, that is, information that “points” to a location of a file in which the image is contained. Pointer information can include file location, web site location where the image can be found, drive location, etc.
The information related to the image can also include date and time information relating to creation of the image, a preferred print mode associated with the image, e.g., “high quality” or “draft,” location of a photo gallery with which the image is associated, and information relating to identification of people or objects contained in the image, such as names of people or objects, location of objects, including Global Position System data relating to objects, etc. In the event the image comprises a text document, information related to the image may include font types, authorship information, creation date, file location, associated word processing program, the electronic file itself, etc.
Information relating to the image printed on the print medium 12 can also include preferred printer settings, revision data format, equipment used to create the image, copyright ownership information, description of the image, proof of authenticity, etc. In addition to this type of identification data, information related to the image on the print medium can also comprise data files, including the original image data file, audio clips that relate to the image, or video clips that relate to the image. The video clip can contain, for example, a video file, one or more frames of which are captured in the image printed on or applied to the print medium.

As shown in
In another aspect of the invention, the information processor 18 can write printing information data to the data storage device 14. In this aspect, information relating to the image to be applied to the print medium 12 can be stored on the data storage device at the time the image is applied to the print medium. Thus, file location and identification information, or file data, etc., can be included on the data storage medium and will remain with the image for later use. In the case where the image data file is stored on the print medium, a user can feed the print medium containing the printed image through the printer, and the printing information processor can read and extract the image data file. The image data file can then be saved to the computer associated with the printer, or used for some other purpose. In this manner, should a user have problems locating the original image data file, the image data file can be retrieved from the data storage device and restored to a computer for further use.
In the embodiment illustrated in
The printer 16 can be of a variety of types as well, as known to those skilled in the art. For example, the printer can be a laser printer, which applies the image to the print medium by applying toner to the print medium 12. In another aspect, the printer can include an ink-jet printer, which applies ink to the print medium. Other known printing systems can be incorporated into the system as well, including thermal transfer printers, dye sublimation, etc.
In one embodiment, the print information processor 18 and print head 22 can be included in an integral unit (not shown). In this aspect, the print medium can be fed past the integral unit for reading or writing to the data storage device, return-fed back past the integral unit, and again fed past the integral unit for application of the image to the print medium. Such an embodiment would allow for the retrofitting of printers currently on the market with print information processors, as print cartridges are typically replaceable in most printers. In other words, a print information processor/ink-jet print cartridge can be made to be integral, and can be controlled by a print cartridge bay (not shown), with or without modification to the circuitry of the printer. In accordance with further embodiments of the invention, the data storage device 14 can be located in a variety of operational locations on the print medium, and the location of the printer information processor can be adjusted within the printer accordingly.
The printing information processor 18 can be configured to write printing information to the data storage device 14 in a number of manners. For example, each time a print job is sent to the printer, a software interface can prompt the user sending the print job if the user would like to write particular print information to the data storage device. The user can then instruct the information processor to write data or information to the data storage device accordingly. For instance, the user may choose to write to the data storage device information relating to the content of the image, or names of individuals shown in the image, or objects depicted in the image, etc. Alternatively, the print information processor can be configured to automatically write a pre-defined set of information to the data storage device, such as the data file containing the image, or the identity and/or location of the data file containing the image.
In addition, while the data storage device 14 is shown in the figures as a generally elongate strip of material, the data storage device can be of a number of sizes and configurations. For instance, in order to increase the storage capacity of the data storage device, the storage device can be of larger size, and in one embodiment (not shown) is of substantially the same size as the underlying print medium 12. In those embodiments wherein the data storage device is substantially invisible to the human eye, as discussed in more detail below, the data storage device can be placed in areas of the print medium where the image will be applied to the print medium, without interfering with or detracting from the image applied to the print medium.
As shown in
Magnetic strip data storage devices are known to those skilled in the art of data storage, and, in accordance with the present invention, can be made readable, writable, and rewritable. The strips (or stripes) are generally comprised of a large number of small ferromagnetic particles or pigments (not shown) that are magnetized in a particular polarization. By magnetizing each pigment to a particular polarization, data can be stored on the magnetic strip and can later be read by a magnetic strip reader. Magnetic strips have been used extensively on devices such as credit cards and identification cards.

While optical data device 14d is shown in
In addition to magnetic strips and optical data storage devices, the data storage device of the present invention can be of a wide variety of those known in the art of data storage. Other examples include printed code, Radio Frequency (“RF”) tags, Radio Frequency Identification (“RFID”) memory spots, flash memory, etc. Similarly, the information data processor (18 in
In the case where the data storage device is both readable and writable, as discussed in further detail above, the data storage device can be used to provide a record of edits or changes to an image, or of identities of users who have read or edited the image. For example, an image in the form of a draft text document may be distributed to a variety of readers, each of whom may make edits or add suggestions to the text. The data storage device can be used to track the users who have read or viewed the image, and track respective edits or comments made or suggested by each user.
In accordance with one embodiment of the invention, the data storage device can be read or written to by an auxiliary read/write device. For instance, a hand-held data reader can be used to record printing information stored on the data storage device in applications remote from the printing process. In this embodiment, the auxiliary device can still be considered to be associated with the printer. This can be advantageous, for example, in those instances where a user may wish to simply read from the data storage device the identities of users who have read or edited an image stored on a print medium. In this case, the user need not have access to a printer, but can simply read the desired information with a data reader.
In accordance with yet another aspect of the invention, a method for associating printing information with a print medium is provided and includes the steps of attaching a data storage device to a print medium, and storing printing information on the data storage device. The step of attaching the data storage device to the print medium can include the further step of adhering the data storage device to an outer surface of the print medium, and embedding the data storage device within the print medium.
In one aspect, the step of storing printing information on the data storage device can include the further step of storing information relating to properties of the print medium on the data storage device. The step of storing printing information on the data storage device can also include the further step of storing information relating to printed material applied to the print medium on the data storage device.
It is to be understood that the above-referenced arrangements are illustrative of the application for the principles of the present invention. Numerous modifications and alternative arrangements can be devised without departing from the spirit and scope of the present invention while the present invention has been shown in the drawings and described above in connection with the exemplary embodiments(s) of the invention. It will be apparent to those of ordinary skill in the art that numerous modifications can be made without departing from the principles and concepts of the invention as set forth in the claims.
