Abstract
Description
- The invention relates to a security document provided with a foil security part.
- It is known to provide security documents, such as banknotes, with a security characteristic, such as a foil area, particularly provided with a metal foil area.
- The advantage of the foil area or part is that it cannot be copied, particularly not by means of a colour photocopier or computer peripheral equipment such as a colour laser printer or inkjet colour printer. Such foil as a result turns out to be a very good security element, because first of all it can easily be perceived by the public, and is hard to copy, the more so as in such a foil area highly advanced further security characteristics can be provided. The security can furthermore be improved by providing the foil with a metal foil area.
- In WO-A1-95/16574 a security document is described which is provided with a foil area that is subdivided into two areas each having a different structure as a result of which they are visually distinguishable.
- In US-A-4.352.706 a metal foil is provided on a security document, particularly in such a manner that at a first angle a first image is visible and at a second angle an image that differs from the first is visible.
- In US-A-5.009.486 a security characteristic is described provided with a coating that is built up such that interference effects occur as a result of which at a first angle a first colour is perceived and at a second angle a second colour.
- WO-A1-2004/014665 regards a security characteristic comprising a metal foil layer of which locally the thickness is reduced so that visually distinguishable areas can be perceived.
- The said characteristics all are so-called public characteristics that are visually easy to perceive and that enable the general public to verify whether or not a document is authentic. Characteristic for these security characteristics is that by means of a technique that is not available to the general public a visual effect is caused.
- When, however, various different additional security characteristics have been provided in a foil area, the foil area has become complex and the public might get confused as to whether the foil area is authentic.
- Therefore there is a need for a further security characteristic.
- Moreover there is a need for improvement of the foil area as a security characteristic.
- To that end the invention relates to a security document comprising a security part comprising a foil area comprising at least two visually distinguishable areas, wherein a first area has a first colour and a second area has a colour that is different and visually distinguishable therefrom.
- By separating two areas that are thus easily visually distinguishable, it is easy for the public to verify whether the foil area is authentic and genuine, and more particularly whether the security characteristics provided for that target group are there.
- In security documents, particularly banknotes, the security characteristics are subdivided into several groups or levels, namely:
- first-degree characteristics: for the public in general;
- second-degree characteristics: for shop keepers, tellers and other professionals handling money;
- third-degree characteristics: machine readable characteristics for use beyond national banks, for instance by automatons, cash dispensers (ATMs), sorting machines, cash recycle machines, and the like;
- fourth-degree characteristics: machine readable characteristics for central banks, such as the European Central Bank or De Nederlandsche Bank;
- fifth-degree characteristics; for banknote experts such as for forensic research.
- In an embodiment of the security document according to the invention further public security characteristics that are visually perceptible by the general public have been provided within the first area, and within the second area further security characteristics have been provided. As a result the general public can easily visually verify whether a security document, and particularly the foil area thereon, is authentic. Preferably the further security characteristics are not visually perceptible just like that, particularly not without using aids intended especially for that purpose. As a result it is easier for various target groups to check the authenticity, as the further characteristics intended for said target group are all placed in a visually easily recognisable area.
- In a further or other embodiment the first area has a different texture than the second area.
- In a further or alternative embodiment the first area has a different gloss than the second area.
- In a further or alternative embodiment the foil area comprises several areas, and the areas are distinct from each other because of colour differences. In this embodiment preferably several, for instance adjacent, areas can be distinguished. All these areas may have a different colour. Another possibility is to give adjacent areas different colours, that means visually distinguishable colours. Preferably, in general, the colours and differences are selected such that they also show a distinction to for instance the colourblind.
- In an embodiment the areas with a colour are provided with a transparent colour, preferably a transparent layer. As a result further visible security characteristics can be incorporated in or under the layer.
- In an embodiment at least one area comprises a metal layer, preferably a metal foil layer. A metal foil layer is not easily reproduced. Moreover the metal layer can be seen through the transparent coloured layer, and further advanced security characteristics can be provided in or on the metal foil.
- In an embodiment at least one area is colourless transparent. In that case the colour is determined by the transparent layer and/or glue layer, and/or the (local) colour of the lower layer is visible, usually the carrier of the security document. In case of a banknote the local colour, or image/image part of the banknote.
- In an embodiment the public security characteristics have been provided in or on a layer of the foil area, for instance on the metal foil, or in the form of parts cut away from the metal foil.
- In an embodiment the further security characteristics have been provided in or on the foil area.
- In an embodiment the foil area comprises at least one metal foil area, of which at least one part of the surface is provided with at least one additional coloured layer, preferably a transparent or translucent coloured layer.
- In an embodiment first-degree security characteristics have been incorporated in at least one first area, and in at least one second area security characteristics selected from the group of second-degree, third-degree, fourth-degree and fifth-degree security characteristics.
- In an embodiment no first-degree security characteristics have been provided in at least one area with security characteristics selected from the group of second-degree, third-degree, fourth-degree and fifth-degree security characteristics.
- In an embodiment no security characteristics selected from the group of second-degree, third-degree, fourth-degree and fifth-degree security characteristics have been provided in an area with first-degree security characteristics.
- In an embodiment the foil area comprises at least one first area and at least one second area.
- In an embodiment the areas connect to each other, preferably seamlessly. As a result an additional difficulty is created offering extra protection.
- A foil area or foil part on security documents, such as banknotes, usually comprise a metal layer, usually aluminium, but possibly copper or another metal, in an embodiment a metal foil. Said layer usually is provided with mostly a synthetic protective layer. The foil area often is provided on the carrier by means of a glue layer. Security characteristics may be incorporated in or on the protective layer, in or on the metal layer or metal foil, and even in the glue layer. A foil area according to the invention may if so desired comprise several metal foil areas, wherein in a further embodiment one or more metal foil areas are at least partially provided with one or more coloured transparent layers. As result areas that are visually distinguishable to the public are created. In or on one or more of said areas further public security characteristics may be provided, that means security characteristics that can be recognised as such by the public.
- For the foil area according to the invention in one embodiment an additional translucent coloured layer is provided on the metal foil layer. Another option is to provide the (colourless transparent) protective layer with a colourant.
- Another aspect of the invention regards a security document comprising a security part comprising a foil area, wherein the foil area comprises at least one metal foil area, wherein at least a part of the metal foil area is provided with a transparent, coloured layer.
- In an embodiment the transparent coloured layer is provided on the metal foil.
- In a further embodiment the metal foil area is provided with at least two areas each having a transparent, coloured layer having a different, visually distinguishable colour. Alternatively the foil itself may be locally coloured.
- All embodiments mentioned can be combined, as a result of which the possibilities for an even better security increase. It is of importance that the foil area has at least two areas, which to the public are visually distinguishable by their colour. Further security characteristics are divided over the various areas in a predetermined way. In an embodiment the areas connect to each other, preferably seamlessly.
- The invention further regards a security document provided with a foil area, and further image elements provided on the security document in a visually perceptible manner, which image elements include among others see-through registers, watermarks, printed image elements, visually perceptible tactile elements, wherein the foil area and the further visually perceptible image elements together form an image, or enhance the visual attention to each other. As a result the mutual positioning of the various parts, that are provided in several operations, becomes critical, which ensures an extra security that is visually easy to verify. In addition the user's attention is drawn to an important area, and it entices further inspection, which is beneficial to the security. Further, as the composition as a whole is visually "correct" and shows coherence, the authenticity can be assessed even without direct comparison with a specimen of which one is sure that it is authentic.
- The invention further regards a security document provided with a foil area provided with at least two visually distinguishable areas, wherein the first area at a first angle of observation has a first colour, and the second area at a second angle of observation that differs from the first angle of observation has a second colour that is different from the first colour and is visually distinguishable therefrom.
- In an embodiment further public characteristics may be incorporated in one of either areas and in the second area further security characteristics or authenticity characteristics. Further characteristics described in this description may if so desired be combined therewith for an additional security.
- The invention further regards a foil area, intended and suitable as foil area on a security document as described above.

Due to the colour the foil area can be divided into twocolour areas area 4 surrounding it. Moreover by providing security characteristics in the metal foil, such as holograms, high resolution structures, such as micro lines, micro diffraction structures, nano structures, small to very small texts, high-reflection structures that may or may not be combined with low-reflection structures, small perforations, transparent areas, and by distributing them over these areas, the possibility is created of verifying whether or not the foil area is indeed authentic. For instance one or more of the said security characteristics can be provided in themid-area 3 only. Some security characteristics may also be provided in themid-area 3, and others in thearea 4 surrounding it. - By providing areas with text wherein the metal layer has been removed, such as for instance the currency symbol of the Euro or the like or incorporating small images or flags such as stars, music, signs, and autographs in one of either coloured parts, and optionally a characteristic that is easily perceptible by the public, such as for instance a hologram or the like, in the second colour part, two clearly distinguishable areas are created that are easily perceptible to the public. The public can therefore address one of either colour areas when verifying, as the security characteristics important to the public have been incorporated therein. The security characteristics that are not intended for the public may be incorporated in the second colour area.
- Figure 2 shows an alternative embodiment of a
foil area 2 according to the invention, wherein again a firstmid-colour area 3 is present, and surrounding itseveral colour areas transparent edge 5. - In each distinguishable colour area for instance another security characteristic can be incorporated, which may or may not be a public characteristic or a further security characteristic. In addition metal foil may be provided underneath the entire colour area, or parts or areas thereof. In an embodiment the colour areas have been provided on the metal foil, and over it a colourless, transparent synthetic protective foil has been provided that extends beyond the metal foil and as a result forms the transparent colourless edge.
- Figure 3 shows an alternative embodiment of a
security document 1 provided with afoil area 2. In this case thefoil area 2 extends over a small part of the longitudinal axis, and over the full width of the security document. - The
foil part 2 again is provided with afirst colour area 3, asecond colour area 4 and colourless,transparent parts 5 along the edges. - Figure 4 shows an alternative embodiment of the foil part of figure 3, wherein this time the colourless, transparent edge extends around the foil area. The overall foil area here extends over the overall width of the security document. The metal foil area here has a
first colour area 3 and further colour areas adjacent thereto and extending to the transparent edge. Said colour areas are indicated with thenumbers - Figure 5 shows various possible shapes of the foil area. The various areas may have the same contour. The contours may also differ to such an extent that two or more areas together emphasise the contour or form a depiction therewith.
- Figures 6A-F show more alternative embodiments of a foil area extending over the full width of a security document. The edges are not straight in that case, and in some embodiments they are not even continuous.
- Figure 7 shows a security document according to the invention provided with a
foil area 2 having afirst colour area 3, asecond colour area 4 and a colourless,transparent edge 5 around thefoil area 2. Aprint 6 has been provided on the security document extending over both the security document surface and over thefoil area 2. Preferably saidoverprint 6 is provided such that it extends continuously from thesecurity document 1 over thefoil area 2. - Figure 8 shows an alternative embodiment of the
security document 1 of figure 7, wherein thefoil area 2 extends over almost the full width of thesecurity document 1. Again anoverprint 6 is provided that runs over thesecurity document 1 where it is not provided with a foil area as well as over thefoil area 2. One of theoverprint parts 6 here runs over thefull foil area 2 such that it extends at both sides of thefoil area 2 on the surface of thesecurity document 1 where thefoil area 2 does not extend. - Figure 9 shows an embodiment of a
security document 1 provided with afoil area 2. Thefoil area 2 is provided here with afirst colour area 3, asecond colour area 4 and a colourlesstransparent edge 5, as has already been described before. Atactile element 7 has been provided on thefoil area 2. Suchtactile areas 7 in a banknote can be felt better on a smooth basis such as thefoil area 2. Optionally the tactile element or elements may extend over thefoil area 2 and over a part of thedocument 1 where there is no foil area, preferably continuously. As a result thetactile areas 7 are better perceptible to the general public as well as to the visually handicapped. The transition from a surface of thesecurity document 1 to thefoil area 2 and from thefoil area 2 to thetactile element 7 is after all better perceptible. - Figure 10 shows an alternative embodiment of figure 9, wherein the
foil area 2 extends over (almost the full) width of thesecurity document 1. Thefoil area 2 in this case is provided with afirst colour area 3, asecond colour area 4 and colourlesstransparent strips 5 which extend along thefoil area 2 and indicate the transition from thefoil area 2 to the rest of thesecurity document 1. - One of either colour areas is provided with
tactile elements 7 on thefoil area 2. If so desired either the one or the other colour area may be provided with atactile element 7, or bothcolour areas tactile elements 7. If so desired thetactile elements 7 may also extend over thefull foil area 2 and if so desired continue on a part of thesecurity document 1 that has not been provided with such afoil area 2. - Under the coloured areas metal foil may be provided, even several metal foil areas, even of different metals.
- Figure 11 shows a further exemplary embodiment of a security characteristic according to the invention, wherein again a
security document 1 is provided with afoil area 2. An indication has been provided over thefoil area 2 by means ofprinting 6. In case of a banknote said indication may for instance be the denomination in print. Thefoil area 2 is provided with an area having afirst colour 3, and an area having asecond colour 4. Thecolour area 4 furthermore has been given a clearly distinguishable shape so that it strikes even more with respect to thecolour area 3. In thiscolour area 4 for instance the public characteristics may be incorporated that are easy to perceive by the public. An example of such public characteristics may for instance be a hologram image or another technical characteristic that is easy to perceive by the public such as for instance a characteristic wherein an image changes colour or something like that. Such security characteristics are generally known per se in the art. Thefoil web 2 is further provided with atransparent part 5 through which the underlying print of the security document can be seen. Furthermore anindication 8 has been incorporated in the foil web, whichindication 8 corresponds to theindication 6 printed over the foil, theindication 6 provided by means of printing. As a result the public can again easily verify whether the foil web is authentic and whether the foil web is belongs to the document. - A security document may furthermore be provided with a security characteristic of which for instance the colour changes when the viewing angle changes. At the start of the introduction to the description a number of such characteristics were mentioned, such as for instance holograms, interference coating layers, metal foils on which various treatments have been performed such as changes in thickness and the like. There are various possibilities to make the various images or depictions visible, for instance by tilting the
document 1 about a longitudinal axis (north-south, N,S) or moving it north-south (shown in figure 12A), or reciprocally moving or rotating it about a latitudinal axis (W, E, figure 12B), or rotating it anticlockwise (+, figure 12C) or clockwise (-, figure 12D). - Tests proved that the general public prefers tilting a banknote about the longitudinal axis as shown in figures 13A and 13B, wherein the public usually first looks at the normal viewing angle, indicated with B, subsequently tilts +60°, indicated with C, and then tilts -30° indicated with indication A.
- The security against counterfeiting by means of three holographic depictions in the foil, that can each be made individually visible in the manner as shown in figure 13 is furthermore considerably increased when each of the depictions is based on one or more different holographic techniques. A selection can among others be made from:
- holographic image elements based on either a symmetrical or asymmetrical line structure;
- holographic image elements based on either a line or dot grid;
- parallel line structures and cross gratings;
- variation of line orientation in both horizontal and vertical or azimuth direction;
- variation of the resolution of the line and/or dot grids, for instance 600 lines/nm for image A, 1000 lines/nm for image B and 1400 lines/nm for image C;
- so-called lenticular? structures (such as the Fresnel lens);
- so-called 'pumping effects';
- combinations of the above-mentioned techniques in a single holographic image or depiction.
- Tests showed that the public considers a combination of three different holographic depictions or images rather much. When two depictions have to suffice, the mid position, depiction B of figure 13A and 13B has to be cancelled. For that matter it is recommendable that the 2 or 3 depictions do not overlap too much, that means that the public can clearly perceive the various holographic images individually at the different angles of perception. The different depictions preferably are provided at the same position on the document.
- Designs for the public part can be made based on structures (pixels and lines) and based on colour. An interplay between these two affords the most protection, figure 14 and 15 are examples of this.
- Figures 14A-14C show a foil security characteristic provided with three
areas - Figure 14A corresponds to a viewing angle of approximately +60° of figure 13A, position C and shows a green traffic light. Figure 14B corresponds to a normal viewing angle of approximately 0° of figure 13A (position B) and shows a yellow traffic light. Figure 14C shows the foil element at a viewing angle of approximately -30° of figure 13A, that means position A, and shows a red traffic light. Due to the playful nature of the series of depictions the foil element entices further inspection.
- The characteristic shown may optionally be combined with other characteristics described herein.
- Figures 15A-15C like figure 14 show a foil security characteristic provided with three
areas areas - Figure 16 shows, as considered from the rear side of the document, a
foil area 2 on asecurity document 1, wherein thefoil area 2 is provided with atransparent part 5 and afirst colour area 4, in this case a piece of a jig-saw puzzle, and asecond area 3, in this case having the shape of a little human figure with raised hands. A transparent contour is left free around the little human figure. When the note or security document is held against the light, thefull area 3 is visible, for instance because with transparent parts, for instance in the form of little circles, the shape of the little human figure is cut away. - The
first colour area 4, in this case a piece of a jig-saw puzzle, in which thesecond colour area 3 is provided, are in register and form a see-through register. When the note orsecurity document 1 is held against the light thefull area 4 becomes visible, otherwise only a part thereof, namelycolour area 3 having the transparent frame. - Figure 17 shows yet another embodiment of the foil characteristic according to the invention, wherein a
security document 1 is provided with afoil area 2 provided with atransparent part 5, afirst colour area 4 in the shape of a piece of a jig-saw puzzle in which further public characteristics can be incorporated, a second colour area (in this case formed by thetransparent part 5 that is provided over a basis having a certain colour or which has a colour itself), and afoil element 7 as further colour area that continues in theprint elements 6. Thefoil area 2 thus forms a visually continuing unity with the elements ofprint parts 6. Moreover theparts 6 provided by means of printing, due to their shape and order emphasise thecolour area 4 that is provided for the public. As a result the public's attention is drawn to thecolour area 4.Colour area 7 of figure 17 can either be incorporated as a foil element or as a print element (part of print parts 6). - Figure 18 shows another embodiment in which a
security document 1 is provided with afoil part 2 provided with atransparent part 4 and afirst colour area 3 in the shape of a piece of a jig-saw puzzle. The foil is partially overprinted bycolour area 5, which is designed as a tactile characteristic. - Figure 19 shows a laminate of a
print layer 1 provided underneath for instance by means of offset or screen printing, or a combination thereof, also called base print. Over it afoil layer 2 is provided in which the characteristics according to the invention or other characteristics have been provided. Over saidfoil layer 2 yet afurther print layer 3 has been provided. Thefoil layer 3 is thus clamped in between twoprinting courses - Figure 20 shows a foil as shown before in figure 11, used here on a Euro banknote, the
overprint 6 in this case being a value number of 10 Euro and the base print being the usual printing course of a Euro note. In between, between theoverprint 6, for instance intaglio, and the standard base print of a banknote, usually a combination of offset technique, afoil web 2 is provided which is provided with the characteristics as already discussed above. - It will be clear that the above description is included to illustrate the functioning of preferred embodiments of the invention and not to limit the scope of the invention. Starting from the above explanation many variations that fall within the spirit and the scope of the present invention, will be evident to an expert.
