Description

FIELD OF THE INVENTION

The present invention relates to a security and/or value document with security features and a verification element for verifying the security features.

BACKGROUND OF THE INVENTION

Security and/or value documents, such as passports, banknotes, and the like, require security against forgery, preferably in a way that allows such documents to be easily inspected for authenticity without the use of external aids.

As a result, it is desirable to incorporate into these products features whereby their authenticity may be checked.

Preferably, these security features should be fixed in an inseparable manner to the product that is to be authorized and/or they should have features that are difficult to reproduce. The invention relates to the manufacture and application of security features for security documents and/or value documents.

Numerous security features are known in the art, such as fluorescent fibres or threads/planchettes/inks, microprints, moiré-generating structures, holograms and the like.

Frequently the security features implemented in products requiring protection consist of special inks having special spectral characteristics, magnetic properties or temperature-dependent behaviour (thermochromic inks). Also used are barcodes which use the difference in reflectivity of the surface. Grid structures or even foil antennae that utilize the resonant frequency of an oscillator circuit are also used.

AU 488 652 discloses security documents where the security features can be inspected by transillumination. Arranged between plastic layers is an optically varying security element viewable through a transparent window in the overlying cover layer. The particular disadvantage is that the applied security features can only be viewed by the naked eye under transillumination, and that the material properties of the document are greatly altered.

The incorporation of a single transparent window on banknotes is also known in the art in Australian banknotes.

DE 43 34 847 A1 describes a value document formed with a window-like cut-out. The window-like opening is in the base material and subsequently covered by a transparent cover film. The cover film in this part of the window can incorporate additional security features. The process of manufacturing the cut-out opening in the base material of the security or value document, to form a window, and then covering this window with a cover film that partly incorporates additional security, is technologically expensive and results in an increase in the thickness of the value document. The requirement that certain parts of the window must remain transparent so that the security features can be viewed by transillumination with the naked eye limits the possibilities of providing security features in a concealed form. Like known window threads used on banknotes, such elements per se, only serve as a security element but have no further function. These known windows may themselves also incorporate security features.

Authenticity-checking of known security elements usually requires special equipment and methods, in particular: external testing devices such as magnifying glasses for checking microprinting, lenticular screens for checking hidden graphical elements, UV lamps to make fluorescent elements visible, or optical recognition of the respective security feature using a transillumination method.

DE 36 09 090 A1 describes a security or value document into which a security thread has been incorporated, which can be viewed visually without the use of technical aids. The security thread consists of a transparent material. Impressed into the upper surface is a screen of cylindrical lenses. Applied directly to the opposite side of the foil of the thread there is a printed image. The printed image is designed with consideration to the optical characteristics of the cylindrical lenses. By suitably designing the printed image accordingly, it is possible to incorporate information that only becomes visible from certain viewing angles.

A disadvantage here is that there is paper arranged directly beneath the thread resulting in the security feature only being viewable through reflection and not through transmission. The security lies solely in the threads which is a conventional security element.

SUMMARY OF THE INVENTION

The object of the present invention is to develop a generically compliant security document and/or value document, in which security against forgery is increased and the document can be inspected for authenticity more easily and without the use of external aids.

Accordingly, the present invention provides a security and/or value document, in particular a banknote, with security features and with a verification element for verifying the security feature, characterized in that at least one verification element and at least one security feature verifiable by means of said verification element are integrated in the document at different positions, and the verification element and the security feature are only superimposed when verification takes place.

Due to the provision of both security features as well as verification means such as detectors for verifying these security features on or in a document, no external means for checking the authenticity of the document are required. The authenticity of security features on a document, for example a banknote, can be checked by means of one or more transparent windows on the same banknote. The combination of security features and a verification system on one and the same banknote increases security against forgery because the verification means can in itself also be designed as a security feature. Both the front and rear side of the banknote can be viewed to check authenticity. By suitably folding a banknote, or any other document in accordance with the invention, or by laying at least one banknote on top of another, it is possible to check the security feature by bringing the security feature into functional relation with the verification system, i.e. the window.

A verification element that has been applied to the value document can be used to check security elements incorporated at different positions in the value document.

For example, in a passport two opposing pages can be used to verify the document. One of the pages can be fitted with the verification element, e.g. a lenticular screen film, on part or all of the page, while the other page may have the security feature that is to be analysed, for example a latently visible screen structure. The authenticity of the document is checked by suitably placing these two pages over each other. Similarly, two banknotes, cheques, or two other equivalent value documents can be checked for authenticity.

Of decisive importance is the functionality of the window or windows integrated in the document. No substantial thickness is added to the document because the security feature and the detection means are located on different parts of the document and not over each other.

The preferred embodiment of the verification element as a detector/analyser or even a decoder in the form of one or more transparent windows, or as a window with two or more analyser areas with detection elements, ensures a multitude of different variations for testing the authenticity of a large number of possible security features.

The verification elements on/in one window or on/in several windows or sections of a window are preferably formed of clear, transparent material and are preferably formed out of one of the following groups:

1. The verification elements can be formed by lenticular lenses/cylindrical lenses/alternating images and autostereoscopic devices, which are located on/in a transparent film or the like and make it possible to see the optically coded security features or structures printed on the document.

The lenticular screens preferably consist of uniform cylindrical lenses, which are arranged parallel to each other, preferably at the same distance apart (e.g. 200 μm). The focus of such a lens screen is preferably matched to the optical thickness of the transparent substrate material used.

The cylindrical lenses can be made in a transparent material, e.g. PVC films, in several different ways, e.g. by imprinting with a suitable mould; or by casting the film in a suitable mould; or by extrusion, using specially formed injection nozzles.

2. The verification elements can be formed by using Fresnel lenses or other similar magnifying optical structures, which facilitate the detection of very fine print or very small graphics on the respective document.

3. The verification elements can be formed by fine graphical structures that are applied—preferably by printing—to both the film of a window as well as to part of the document.

The window can form a mask for a “parallax-barrier display”.

When the corresponding surfaces (window/security feature on the document) are placed on top of each other, so-called moire structures may be generated. Together with the line or dot screens in the area of the security feature on the document, the line or dot screens on the window form such a moire structure. The moire pattern thus formed is the characteristic security feature for the value document.

If the windows are arranged in such a manner that they are placed on top of each other when the document is folded, then structures in accurate register can create colour or pattern changes when the two surfaces are moved relative to each other.

4. The verification elements can be formed as polarization filters.

In one preferred embodiment, two clear windows are arranged adjacently or a window is divided into two analyser areas.

The windows can be embodied as two polarizers for viewing polarisation stereo images.

One specially formed window can produce a “Polaroid-Vectograph”.

Windows can be formed in such a way that a switch in contrast from transmitting to opaque can be implemented. Such structures can be implemented by half-wave zones applied to a linearly polarizing film. For example, by suitably oriented films of correct thickness.

The bright and dark areas of an image may be linearly polarizing areas with alternating horizontal and vertical polarising directions.

Windows can be formed, that implement a clear switch in colour based on the “colour shutter” principle.

5. The window can be embodied as an interference filter or colour filter. Transparent diffraction structures, multilayer systems are examples of interference filters.

The transparent window can be embodied as a holographic filter that reflects a narrow spectral range, either

• • analogous to holographic laser-protection spectacles, or
  • a compound colour appears in a different colour, or
  • a pure spectral colour disappears.

Such a filter is also suitable for two clear windows, whereby the verification window may be subdivided into a holographic part and a non-filtering adjacent part.

The windows can be designed as two colour filters for viewing anaglyphs (stereo images) or as prisms, preferably as gradient-index prisms (superchromatic where possible) for a chromastereoscopic image.

Further advantageous embodiments of the present invention will become apparent from the dependent claims.

DETAILED DESCRIPTION OF THE EMBODIMENTS

According to the representation in FIG. 1, a value document, e.g. a banknote 1, is formed with one transparent window 2. The transparent window, which is provided with verification elements, serves as a detector or the like to verify a security feature located in zone 3 of the banknote 1. Verification of the security feature in zone 3 of the banknote 1 is accomplished, for example, by laying the two zones 2 and 3 one over another.

In a first embodiment, the window 2 in FIG. 1 is provided with a lenticular screen that serves as a verification element. The orientation of the lenticular screen in the zone of the window 2 and the correspondingly printed screen, which serves as a security feature in zone 3 of the banknote 1, must be co-ordinated in such a way that the required effects become visible when zones 2 and 3 are brought to overlap each other, for example by folding.

The printed screen structures serving as the security feature in zone 3 can be created with any type of printing technique that is applied in security printing, preferably the simultaneous-offset method (Letterset) because of the high resolution required.

FIG. 4 shows a simple example of the creation of screen structures in the form of the letter “D.” By superimposing the lens screen in window 2 with the line screen 4 in zone 3, a clear image 7 of the letter “D” appears to the observer.

Also, printed line structures in combination with embossments, which show so-called tilt effects (DE 23 34 702), and which are preferably created using the intaglio process, can be made visible by suitably superimposing zones 2 and 3 (FIG. 1) of the banknote 1, whereby zone 2 must have the lens screen to enhance the tilt effect.

The lenticular screens preferably consist of equal-type cylindrical lenses, which are arranged parallel to each other, preferably at the same distance apart (e.g. 200 μm).

These cylindrical lenses can be introduced into a transparent material, e.g. PVC films, in several different ways, e.g. by casting a film on a belt with a negatively formed profile or by extruding lens screens by way of specially formed injection nozzles, e.g. wide-slit nozzles.

The cylindrical lenses can also be produced by impressing with a suitable mould, or by rolling out films between rollers that have a corresponding negative profile.

Gradient-index lenses can be made out of bleached silver halide layers or photo-polymers.

In a second embodiment example according to FIG. 1, the verification element in window 2 of banknote 1 is formed by Fresnel lenses or similar magnifying optical structures that facilitate the recognition of very small type or graphical elements in zone 3 of document 1 when zones 2 and 3 are suitably laid over one another. Here the very minimal thickness of the Fresnel lenses together with the good magnification of the lens, e.g. 5 to 10-fold, is an advantage for integration into the substrate materials.

According to a third embodiment, the verification element in window 2 of the banknote 1 in FIG. 1 is formed by fine line structures, which are also formed on a part of document 1 in zone 3. When the corresponding zones 2 and 3 of document 1 are overlapped, so-called moire structures are generated. Examples of moire-generating patterns are described in DE 28 19 640, DE 23 24 702, DE 26 03 558, DE 36 02 563.

The verification element in window 2 may consist of a printed line or dot screen for a visual coding/decoding method for a banknote 1. In addition to printing fine dots and/or lines, it is also possible to punch zone 2 (the window) of the document 1 or to perforate it, preferably by means of laser perforation, so that by suitably superimposing zones 2 and 3 of the banknote 1, e.g. by folding, a moiré pattern is produced. Zone 3 of the banknote 1 may consist of a transparent material with printed lines/screen, an opaque material with a printed line/screen or a zone with a suitable perforation, preferably a laser perforation.

In a fourth embodiment, a polarizing filter is integrated on/in a preferably transparent film material as a verification element in zone 2, e.g. of a banknote 1, in combination with a further similarly designed polarizing filter in zone 3. The polarizing filter in zone 3 is preferably designed perpendicular or parallel to the polarizing filter in zone 2 and serves as an analyser, so that suitable overlapping of zones 2 and 3 of the banknote 1 and rotation of the overlapping zones 2 and 3 against each other will cause the optical transparency (bright/dark) to alternate or change.

In a further embodiment, an additional dichroic (double refracting), graphically structured layer is applied, e.g. by printing, sputtering, casting or such like, so that suitable overlapping of zones 2 and 3 of the banknote 1 and rotation of the overlapping zones 2 and 3 against each other will cause a graphic element, e.g. a letter, to become visible.

A further embodiment is achieved when one of the two polarisation filters in zones 2, 3 is replaced with a reflecting layer, whereby an additional dichroic, graphically structured layer is applied to this reflecting layer. Suitable overlapping of zones 2 and 3 of the banknote 1 and rotation of the overlapping zones 2 and 3 against each other cause a graphic element, e.g. a letter, to become visible.

A further embodiment provides that one of the two polarisation filters is replaced with a reflecting layer, whereby an additional dichroic, graphically structured layer is applied to this reflecting layer. This double-refracting transparent layer can preferably be in the form of a liquid-crystal-containing film. Suitable overlapping of zones 2 and 3 of the banknote 1, e.g. by folding, then rotating the overlapping zones relative to one another causes a graphic element, e.g. a letter, to become visible.

For many verification effects it is desirable to be able to position two different verification elements over the security feature quickly and easily. This often eases the perception of changes in the case of movement-effects or colour-switching effects. It facilitates verification in cases where a rotation of the verification element with respect to the security feature is necessary. With a single verification window 2, such a rotation would be very impracticable. To solve these problems, it is proposed that the verification window 2 be divided into two adjacent analyser areas (FIG. 2, 2a through 2d) or that two adjacent windows 2 (FIG. 3) be arranged with different verification elements.

FIG. 2 c shows an embodiment of a verification window 2. At least two clear analyser zones 5, 6 are arranged adjacently to serve as verification elements on the banknote 1. The analyser zones 5, 6 are preferably holographic prisms, if possible embodied as superchromatic prisms, for a so-called chromastereoscopic image. Preferably the prisms are embodied as gradient-index prisms in the form of thin film materials.

An embodiment according to FIG. 2a provides that at least two adjacently arranged clear analyser zones 5, 6 in a window 2 are embodied as a so-called “Vectograph”. A Vectograph consists of two polyvinyl-alcohol films, which form linear polarization filters when they are printed with iodine paints. The two films are arranged in such a way that when the front side contacts the iodine paint vertical polarization results, and when the rear side contacts the iodine paint horizontal polarization results (FIG. 2a, 2b). Iodine paint is used to print a selected first pattern, for example a square 10 (FIG. 2a, 2b), on the front side, and a selected second pattern, for example a star 11 (FIG. 2a, 2b), on the rear side. When the two superimposed films are viewed with a linear analyser (window 2, zone 5 in FIG. 2a, 2b), the first pattern (square 10) becomes visible when the analyser is oriented horizontally (zone 5), and the second pattern (star 11) becomes visible when the analyser is oriented vertically (zone 6). In the same manner is also possible to implement colour changes.

A verification window 2 divided in this manner with analyser zones 5, 6 makes it unnecessary to have to rotate the window 2; the window 2 only needs to be shifted.

Similarly formed zones 5, 6 can be designed to achieve a contrastive change from transmitting to opaque. Such structures can be implemented by applying to a linear polarizing film 8 (FIG. 2d) so-called “half-wave” zones 9 (phase plates with a phase shift of 1800 between ordinary and extraordinary rays), for example by means of suitably oriented film materials of the correct thickness (FIG. 2d). The polarization direction is rotated 90° in these zones. This effect is particularly impressive with area-filling patterns. Similarly formed build-ups serve to implement a clearly discernible colour switchover based on the “colour shutter” principle.

In a further embodiment of the verification element(s) in window 2 of the banknote 1, interference colour filters, generally transparent refraction structures and multilayer systems can be used.

The interference colour filters are formed in/on a preferably transparent film material or they consist of this material. The filters are integrated for example on a banknote 1 in zone 2 in combination with a coloured graphical element in zone 3. When zones 2, 3 of the banknote 1 are suitably overlapped, a certain spectral range in the graphic element, for example a character, is blanked out by zone 2 or allowed to pass through, so that a colour impression is perceived that differs from the original colour.

For the interference/colour filters, it is possible to use both coloured transparent materials, and transparent materials with colours vacuum-metallised/sputtered or printed onto them.

In a further embodiment, at least two clear analyser zones 5, 6 are arranged adjacently according to the representation shown in FIGS. 2 and 3. These zones 5, 6 may be formed by at least two colour filters for viewing so-called anaglyphs (stereo images). The anaglyphs are located in zone 3 of the banknote 1. When zones 5, 6 and 3 are placed over one another at a certain distance from each other, a stereoscopic-impression is created.

All the windows can be embodied in any desired form, preferably in a form that is best suited to the respective selected verification element; thus the embodiment can be thread-like or, as shown in FIG. 5, triangular in shape.

The windows can be formed at any positions on the document, including on a corner of the document, as shown for example in FIG. 5; the requirement is only that it must be possible to bring the security feature and the verification element for verifying the security feature together in such a way that they have a functional interrelation, for example by folding, twisting, or superimposing one or more documents.

Superposition can be accomplished by direct contact or, in some cases, with a gap between the security feature and the verification element.
