Description

Field of the invention:

The present invention relates to a value or security product having a product body with two outer sides. Such products are usually equipped with at least one non-individualizing security printing and at least one individualizing security feature. Furthermore, the present invention also relates to a method for producing such a value or security product.

Prior art and background of the invention:

Value or security products, in particular securities or security documents, are used to verify the identity of a person, in particular when crossing a state border, or thing or claim, for example, on payment of a sum of money or on the release of a product or service. For this purpose, it must be ensured that the product can not be imitated, counterfeited or falsified with considerable effort. The product therefore contains security features whose imitation is extremely difficult or even practically impossible. For example, the product, such as banknotes, consists of a not readily available material. Additionally or alternatively, security features can be provided by special colors, for example luminescent or optically variable colors, optical elements such as holograms, tilt images, kinegraphic objects, lens or prism arrays, also guilloches (with visible colors / inks or luminescent colors / inks), mottled fibers, security threads and others, be formed.

The security features used in the value or security products, in particular securities or security documents, can only serve to prove the authenticity of the documents, regardless of their nature or by their user. Personalizing, for example, personalizing security features also contain in coded form or in plain text information about the type of document, about the user this document and / or an item to which the document is clearly assigned. Such information may be a facial image (photograph) of the user, his or her personal data such as name, date of birth, place of birth, address, or a personal identifier such as a membership number or his / her signature. Another security feature that individualizes the value or security product can be, for example, a serial number of the product or the chassis number of a motor vehicle to which the product is assigned.

Identification documents are generally initially produced in the form of non-individualized blanks (product bodies). This production section typically takes place in a central production site, since the blanks do not differ from each other and can therefore be mass produced. Individualization, for example personalization, of the blanks can also be carried out in the central production, for example by affixing the name, the address, the date of birth and the place of birth as well as a face image of the document holder in the document. However, the execution of this processing step in a central manufacturing plant is logistically disadvantageous. For this reason, it is preferred to decentralize the documents in order to be able to ensure rapid processing, for example in outlets for value or security documents.

It is usually assumed that security features and in particular individualization data are to be affixed to an internal level of the security or security product, since in this way it can be better ensured that the products are less susceptible to tampering attempts:
For example, it is off DE 10 2011 006 191 A1 a laminate formed from at least three laminate layers known, which can be used as a security and / or security document. The laminate body comprises at least two color fields, which are arranged one above the other and each of which lies in one of at least two color planes. The color fields are preferably printed with printing inks. The color planes are arranged inside the laminate body. It should be noted that the fact that the color planes are arranged inside the laminate body, a manipulation of lying in the color planes ink layer areas strong would be difficult because the ink layer areas extracted for manipulation and the laminate body would have to be delaminated at least in the range of these color layers.

Furthermore, in DE 10 2008 012 420 A1 a document with a security print described. In each case image information is introduced into a plurality of layers of the document, the image information being supplemented to form an overall image. The image information is generated by an ink-jet printing method. It should be noted that it is advantageous to arrange the printed layers on internal layers of the composite. In this case, a forgery or falsification of printing layers serving as security features is made difficult or even impossible.

An introduction of customization data in a blank is possible in a decentralized manufacturing plant only with special manufacturing processes. For example, personalization data may be written to a card inlay by means of a laser beam ( DE-PS 29 07004 B1 ).

An individualization of a value or security product by means of laser engraving, as in DE-PS 29 07 004 B1 Although it is possible to generate the individualization data in an internal level in the product, they are largely secured against manipulation. However, a black-and-white reproduction of the individualization data is possibly possible with this method. However, a multi-color rendering of, for example, personalized information, such as a facial image of a person uniquely associated with the product, would be desirable as it would allow, for example, better recognizability and more generally a safer assessment of the authenticity of the value or security product.

Out EP 0 273 348 A2 Furthermore, a high security identification card is known, which is formed according to the preamble of claim 1.

The objects underlying the invention:

It is therefore the object of the present invention to generate individualization data in a decentralized production site even in multicolored representation on a value or security product. The multicolored representation should be able to be formed in photo quality. Accordingly, it should not be readily possible to manipulate the data distort). In addition, the manipulation should be made easy to see them easily recognize the value or security product can.

definitions:

As far as used in the description and in the claims of the present application, the term, value or security product ', which may be in particular a valuable or security document or a security element is used, for example, a passport, identity card, driver's license, an access control card or a other ID card, a vehicle registration document, vehicle registration document, visa, check, means of payment, in particular a banknote, a check, bank, credit or cash card, customer card, health card, chip card, a company card, proof of entitlement, membership card, gift or purchase voucher, Bill of lading or other proof of entitlement, tax stamp, postage stamp, ticket, token or other document to understand. A product according to the invention may also be a security element, for example a sticker, adhesive label (for example for article surveillance), patch or the like, having the security feature according to the invention and having a precursor of a security or security document or another article, for example with one to be marked An article whose authenticity is to be guaranteed can be permanently connected to form the value or security document or this marked article. For example, this item may be a copy of a limited series of similar items whose uniqueness is documented by numbering. This numbering can be realized by the individualization of the security element provided with the security feature. The value or security product can also be a smartcard, for example. The value or security document may be in ID 1, ID 2, ID 3, or any other normalized or non-normalized format, such as in a booklet form, such as a passport-like item, or, for example, in card form. A value or security product is generally a laminate of several document layers, which are connected in register under the action of heat and under increased pressure. These products should meet the standardized requirements, for example according to ISO 10373, ISO / IEC 7810, ISO 14443. The product layers consist for example of a carrier material that is suitable for a lamination.

The value or security product may be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate, polyethylene terephthalate (PET), their derivatives such as glycol modified PET (PETG), polyethylene naphthalate (PCT). PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS), polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and their derivatives, or paper or cardboard or glass or metal or ceramic. In addition, the product can also be made of several of these materials. It preferably consists of PC or PC / TPU / PC. The polymers may be either filled or unfilled. In the latter case they are preferably transparent or translucent. If the polymers are filled, they are opaque. The product is preferably prepared from 3 to 12 films, preferably 4 to 10 films. The films may also carry print layers. In any case, according to the present invention, there is a security pressure on the side of at least one of the outer foils which lies on the outside in the laminated value or security product.

Broad features of the invention and preferred embodiments:

According to a first aspect of the present invention, the above objects are achieved by the value or security product according to the invention. The value or security product is formed by a product body (non-individualized blank) with two outer sides. The value or security product has at least one non-individualizing security print and at least one individualizing security feature. The at least one non-individualizing security print and the at least one individualizing security feature are printed overlapping on at least one of the outer sides of the product body in the same printing plane. At least one of the outer sides of the value or security product is covered with a structured protective layer.

1. (a) Herstellen des Produktkörpers, der zwei Außenseiten aufweist, wobei sich auf mindestens einer der zwei Außenseiten mindestens ein nichtindividualisierender Sicherheitsdruck befindet;
2. (b) zumindest auf die den mindestens einen nichtindividualisierenden Sicherheitsdruck aufweisende Außenseite des Produktkörpers wird mindestens ein individualisierendes Sicherheitsmerkmal in derselben Druckebene überlappend aufgedruckt, wobei das Wert- oder Sicherheitsprodukt gebildet wird; und
3. (c) zumindest die den mindestens einen nichtindividualisierenden Sicherheitsdruck und das mindestens eine individualisierende Sicherheitsmerkmal aufweisende Außenseite des Produktkörpers wird mittels einer Schutzschicht überzogen. Die Schutzschicht wird strukturiert oder strukturiert aufgebracht.

According to a second aspect of the present invention, the above-mentioned objects are also achieved by the inventive method for producing the value or security product with decentralized individualization, in particular personalization. The method comprises the following method steps:

1. (a) producing the product body having two outer sides, at least one non-individualizing security print being located on at least one of the two outer sides;
2. (b) at least on the outside of the product body having the at least one non-individualizing security pressure, at least one individualizing security feature is printed overlapping in the same printing plane, the value or security product being formed; and
3. (C) at least the outside of the product body having the at least one non-individualizing security print and the at least one individualizing security feature is coated by means of a protective layer. The protective layer is applied structured or structured.

With the value or security product according to the invention and the method for producing the value or security product, the possibility of multicolored production of an individualizing mark in a decentralized manufacturing facility is opened up. Because the product body can be made without difficulty with conventional technologies with this mark on the outside by the license plate is printed, for example, in a conventional manner.

Furthermore, it is ensured with the inventive value or security product that a falsification of the value or security product is easily recognizable. This is achieved by making an intimate connection of the ink / ink for the individualizing security feature with the ink / ink of the non-individualizing security print because that security feature and security print are overlapping on the outside of the product body in the same print plane. If a counterfeiter tries to remove the distinguishing marks from the value or security product so that subsequently a changed individualizing mark can be attached, the non-individualizing security print is removed at the same time and without the counterfeiter being able to prevent this. Since the security pressure generally extends over a larger area of the surface of the valuable or security product and also overlaps, for example, with still other security features, a replacement of the security pressure with reasonable effort is not possible. Therefore, such a manipulation of the value or security product remains recognizable on the basis of the at least partial destruction of the security pressure.

Another advantage of the present invention is that a value or security product with a small thickness, in particular in the form of a thin card, can be produced, since for the at least one individualizing security feature and the at least one non-individualizing security print, which are created in a common printing layer, only one slide must be claimed.

The individualizing security feature may be any common identifier for individualization, in particular personalization, of the value or security product, for example the personal data of a document holder, such as name, date and place of birth, address or root number of the document holder, or a serial number of the document or another identification mark. This data can be reproduced with alphanumeric characters, for example. Furthermore, the individualizing security feature can be formed by biometric data, such as a fingerprint, a face image, the hand-line structure, iris or retina, or by its own handwritten reproduction of the name of the cardholder (signature). The biometric data as well as the signature can all be reproduced in pictorial representations.

The non-individualizing security printing can be formed by any pattern or other representation of a non-individualizing the value or security product image, for example, by guilloches, a wallpaper, carpet or fabric pattern, a visual representation of visual art or other graphic design.

Both the at least one individualizing security feature and the at least one non-individualizing security printing can either be applied only to an outer side of the product body, or at least one individualizing security feature and at least one non-individualizing security print can be located on both outer sides of the product body.

Both the non-individualizing security printing and the individualizing security feature can be formed with printing inks / inks that produce a visually recognizable printed image. For this purpose, the printing inks / inks used for this purpose contain suitable pigments and / or dyes which absorb in the visible spectral range. Such pigments and dyes are well known and common in the art. Alternatively or additionally, the printing inks / inks may also contain luminescent pigments and / or luminescent dyes (luminescence = fluorescence, phosphorescence) which again absorb in the visible spectral range and therefore are visually recognizable and / or not absorb in the visible spectral range, but in another spectral range, for example in the IR or UV spectral range. The latter pigments and dyes can luminesce, for example, in the visible spectral range, so that they give a visually detectable luminescence after excitation with electromagnetic radiation, for example in the IR or UV spectral range. The inks / inks for the at least one individualizing security feature and the at least one non-individualized security print may be different with respect to the above alternatives.

In a preferred embodiment of the present invention, the individualizing security feature is printed with a polycarbonate based ink / ink. Such ink / ink accordingly contains a binder formed by a polycarbonate. By using this ink / ink there is the advantage that the ink / ink with the material on the outside of the product body firmly connects and thus can not be easily removed, especially if the material of the product body is also made of polycarbonate or contains this , at least on its outer sides. Suitable polycarbonate binders are in principle all conventional polycarbonate materials, for example polycarbonates, which are obtained using bisphenol A. Particular preference is given to polycarbonates as binders for printing inks / inks, which are prepared by using a geminally disubstituted dihydroxydiphenylcycloalkane, preferably monomers such as 4,4 '- (3,3,5-trimethylcyclohexane-1,1-diyl) -diphenol, 4,4 '- (3,3-dimethylcyclohexane-1,1-diyl) diphenol or 4,4' - (2,4,4-trimethylcyclopentane-1,1-diyl) diphenol. Such polycarbonates are in DE 10 2007 052 947 A1 (Local component A) described. The disclosure of this document, at least with respect to the starting materials and preparation conditions for polycarbonates, is hereby incorporated by reference into the present application.

In a further preferred embodiment of the present invention, the product body is made of a polycarbonate or contains at least one of the outer sides or sides printed with the at least one non-individualizing security print and the at least one individualizing security feature. Of course, the entire product body may be made of or contain polycarbonates. For the purposes of the present invention, it is sufficient if only the outer sides of polycarbonate exist or at least contain this. For example, only arranged on the outer sides of film layers of a laminated product body may consist of polycarbonate or contain this. Or it can also be more film layers, which are arranged between the outer layers of film, made of polycarbonate or contain this. By using polycarbonate-containing outer sides, at least on the outer side, on which the at least one non-individualizing security print and the at least one individualizing security feature are arranged, an even firmer connection is established between the printing ink / ink for forming the individualizing security feature and the product body , This is especially true when the ink / ink is formed to form the individualizing security feature in the manner explained above based on a polycarbonate.

In yet another preferred embodiment of the present invention, the at least one individualizing security feature has penetrated into the outside of the product body, for example by diffusion. With this measure it can be achieved that the printing ink / ink of the individualizing security feature is less easily removable from an outer side of the product body than the printing ink / ink of the non-individualizing security print. If a falsification of the value or security product is therefore attempted, the security pressure arranged there is at least damaged before the individualizing mark is removed.

In order for the ink / ink of the individualizing security feature to penetrate into an exterior of the product body, the ink / ink can be matched to the material of the exterior to which it is printed.

One way of such a vote is in a preferred embodiment of the present invention is to select for the ink / ink on the one hand and the material of the product body on the other hand, chemically similar materials, ie materials that each consist at least substantially of the same polymer. It is very particularly preferred if both the printing ink and the outer side material of the product body consist of or contain polycarbonates.

A further alternative or additional possibility of such a coordination of the materials to one another according to a further development of the present invention is to select the composition of the printing ink / ink in such a way that it contains a solvent that is compatible with the material of the outer sides of the product body. The solvent is believed to have the effect of dissolving the material on the outside of the product body so that the ink / ink can penetrate into the material. For a binder based on polycarbonate suitable solvents in DE 10 2007 052 947 A1 indicated (local component B). The disclosure of this document, at least with respect to the solvents for the ink composition, is hereby incorporated by reference into the present application.

In order for the printing ink / ink for the at least one individualizing security feature to penetrate into the outer side (s) of the product body, in particular according to a further development of the present invention, it can additionally or alternatively also be provided that the product body is printed during the printing of the individualizing security feature ( Process step (b)) is heated to a temperature above room temperature, for example to a temperature of at least 40 ° C, more preferably of at least 50 ° C, even more preferably of at least 60 ° C and even more preferably of at least 65 ° C. The maximum temperature which should not be exceeded in order to prevent the material of the product body from being deformed, excessively expanded or subjected to other adverse influences under the action of heating, depends on the nature and composition of the product body and the ink / ink dependent. Therefore, the maximum temperature is preferably not more than 120 ° C, more preferably not more than 110 ° C, still more preferably not more than 100 ° C, even more preferably not more than 90 ° C, and most preferably not more than 80 ° C. If the temperature is too high, there is a risk that the position accuracy of the pressure can no longer be guaranteed. The product body is therefore most preferably heated to about 70 ° C during printing with the at least one individualizing security feature.

In a further preferred embodiment of the present invention, the non-individualizing security pressure extends over the entire outside of the product body. Alternatively, the non-individualizing security pressure can also cover only a partial area of the outside of the product body, for example in a surface area of maximum 25%, more preferably at most 50% and most preferably at most 75%. This area coverage is preferably at least 10% and more preferably at least 15% and most preferably at least 20%. As a result of this planar expansion, preferably over the entire surface of at least one of the outer sides of the product body, it is achieved that a reconstruction of the non-individualizing security print after its damage due to a manipulation on the individualizing security feature is particularly difficult, if not impossible.

This reconstruction is particularly difficult according to yet another preferred embodiment of the present invention, when the non-individualizing security printing extends over an area on the outside of the product body in which there is another security feature of the value or security product, i. overlaps with this further security feature, and even more preferred if this further security feature is also arranged in the same plane in the value or security product in which the non-individualizing security printing is arranged. Because in this case, this further security feature would also be affected in a reconstruction of non-individualizing security printing. It is further preferred if this further security feature is likewise a printing feature. Most preferably, this further security feature is a printing feature located in the same printing plane as the non-individualizing security print.

In a further preferred embodiment of the present invention, the non-individualizing security printing may first be printed on the films which are provided for the production of the product body by lamination, and not on at least one of the outer sides of the finished laminated product body. This approach offers the advantage of simpler printing technology, since the films can be easily processed in a roll-to-roll process, while the laminates are available only in one piece and thus a continuous print production is not possible. In addition, because of their greater thickness, the laminates are less flexible and thus can not readily be processed by conventional printing techniques.

To produce the at least one non-individualizing security printing, customary printing processes can be used, such as offset printing, flexographic printing and screen printing. Preferably, a web offset printing process is used.

The laminate may, in addition to the non-individualizing security print and individualizing security feature printed on the at least one outer side of the product body, also have print layers on surfaces lying in the laminate. These inner print layers are printed on the films prior to lamination, which are then laminated together. As well as the non-individualizing security printing and the individualizing security feature, the inner printing layers can be produced with conventional printing inks / inks. Again, these inks / inks contain suitable pigments and / or dyes which absorb in the visible spectral region and are well known and conventional in the art. Alternatively or additionally, these printing inks / inks may also contain luminescent pigments and / or luminescent dyes which may have the spectral properties mentioned in connection with the non-individualizing security printing and the individualizing security feature.

In a further preferred development of the present invention, at least one internal design pressure can furthermore be provided as the printing layer. The at least one design print and the at least one non-individualizing security print are in each case in the form of at least one security mark passergenau and complementary to each other arranged so that the at least one security mark only by a manipulation of the value or security product is recognizable and is present without manipulation only latent ie is imperceptible. Design printing is the negative to the non-individualizing security printing or vice versa. Free areas in design printing thus encounter pressure areas in non-individualizing security printing, and open spaces in non-individualizing security printing encounter printing areas in design printing, ie the free areas and pressure areas of the two prints are preferably one above the other when viewed vertically from the value or security product. Alternatively, the free areas or pressure areas of both prints can also be viewed at a certain angle relative to the surface normal of the value or security product, for example at an angle in a range of over 0 ° to 80 ° to the surface normal, complement, so that the security indicator is then imperceptible (latent), if the non-individualizing security printing is undamaged, but then becomes noticeable when the non-individualizing security pressure is at least partially removed by a manipulation, so then only by the design print formed part of the safety mark is recognizable. The design print can be designed in the form of a security print, for example in the form of guilloches.

In order that the non-individualizing security printing on the outside of the film stack provided for the lamination during lamination does not contaminate the laminating sheets, in a further preferred embodiment of the present invention separating layers can be arranged between the laminating sheets and an external non-individualizing security printing. Such release liners can be formed for example by films of polyimide, polyethylene, polyethylene terephthalate or an acrylate-epoxy-modified polyester. These films do not bond with the outer sides of the product body and can therefore be removed again after lamination.

For the lamination several stacks of films are processed, for example, either simultaneously in a platen press or sequentially in a continuous system under pressurization and heat input. In particular, when the films are formed of polycarbonate, the lamination typically in a hot / cold laminating press in a first step at 170 ° C to 200 ° C and a pressure of 50 N / cm ² to 600 N / cm ² and in a second step, with cooling to about room temperature and carried out under the same pressure.

Since the laminates are preferably produced in the form of multiple benefits (cards, sheets, pages), the individual benefits after lamination of the multiple benefits are available by dicing. For this purpose, for example, a punching method can be used. The individual benefits have the desired format, for example the ID 1, ID 2 or ID 3 format according to ISO / IEC 7810.

To produce the at least one individualizing security feature, the printing ink is preferably printed by a digital printing method (non-impact printing method), since this offers the required flexibility for the purposes of individualization. All Particularly preferred is an inkjet printing process (inkjet printing process), since with this the printing inks required for the formation of the desired printing quality are available. For the purpose of producing the individualizing security feature, it is possible to use all available ink-jet printing methods and the inkjet printing devices (printers) available for this purpose, for example drop-on-demand methods and continuous inkjet methods. For example, a suitable printing ink based on polycarbonate in DE 10 2007 052 947 A1 described. The disclosure of this document, at least in relation to the description of the composition of the preparation as printing ink, the starting materials required therefor and the conditions of production of the ink, is hereby incorporated by reference into the present application.

Since the individualizing security feature is generated in the same plane as and overlapping with the non-individualizing security print and printed on at least one outer side of the product body, the ink for the individualizing security feature strikes areas on the outside in which already ink / ink of the non-individualizing security pressure. The ink / ink for the individualizing security feature settles over the already solidified ink / ink of the non-individualizing security print and preferably penetrates, in particular diffused, into the material on the outside of the product body where the solidified non-individualized ink / ink is located , As a result, the already solidified ink / ink of non-individualizing security printing is surrounded on almost all sides by the ink / ink of the individualizing security feature. This configuration protects the individualizing security feature against adulteration, since the close interpenetration of the printing inks / inks of both security features makes isolated manipulation of the individualizing security feature impossible. A manipulation is made immediately visible, possibly after excitation (for example with 365 nm radiation) of printing inks / inks, which are otherwise visually imperceptible in the visible spectral range.

The finished laminate can finally be coated on one or both sides with the protective layer, for example with a protective or topcoat or with a film after singulation in single-use. The film may in particular be a patch, hologram, a kinegraphic element or a scratch-resistant film. Protective layers formed in this way secure a security feature arranged underneath, giving the document the required abrasion resistance and protect it against scratches and other damage as well as against environmental influences, such as moisture and chemicals, so that the value or security product has the long-term stability required, for example, according to ICAO. For this purpose, at least the non-individualizing security printing and the individualizing security feature having outside of the value or security product in a preferred embodiment of the present invention is coated with a protective layer.

The protective or topcoat can be formed by UV-curing printing inks / inks, for example based on acrylic resin, which are optionally filled with nanopigments to increase the scratch resistance. It is preferably transparent, but at least translucent and in any case so transparent that the underlying non-individualizing security printing and the individualizing security feature are visually perceptible. The protective layer preferably covers at least the area which is occupied by the individualizing security feature on the at least one outer side of the valuable or security product. In particular, the protective layer preferably extends over a larger area of the at least one outer side than the area occupied by the at least one individualizing security feature, namely preferably over an area of not more than 25%, more preferably not more than 50% and even more preferably not more than 75% respective outside of the value or security product. This area coverage is at least 10% and more preferably at least 15% and most preferably at least 20% of the respective outside of the security or value product. It is most preferred if the protective layer completely covers the at least one outer side of the valuable or security product, wherein it is further preferred if both outer surfaces are coated over the entire surface with the protective layer.

According to the invention, the protective layer is structured. For example, according to a predetermined (lateral, ie extending parallel to the outside of the product body) structure, the protective layer may have regions which are thinner or alternatively thicker than the remaining regions of the protective layer. For this purpose, either an already produced protective layer is structured (either by further application of lacquer material or by partial removal of the protective layer), or the protective layer is applied in a structured manner to the outside.

The structuring of the protective layer can be in the form of an individualizing or non-individualizing characteristic. In a preferred embodiment of the present invention, the structuring is in the form of an individualizing security feature, for example in the form of a biometric feature of the owner of the valuable or security product. Alternatively or additionally, the structuring may also be in the form of a non-individualizing mark, for example in the form of a logo. Most preferably, the structuring is in the form of a feature which already exists in another form, for example by the individualizing security feature according to the present invention, on the valuable or security product. These two security features (individualizing security feature according to the present invention and individualizing structuring of the protective layer) can be arranged in overlapping regions on the outside or in non-overlapping regions. Alternatively, these two security features can also be arranged in register one above the other.

The structuring may extend over the entire surface of the protective layer or only over a part of this surface, for example over at most 25%, more preferably at most 50% and most preferably at most 75% of this surface. The area coverage of the patterning feature in the protective layer is at least 10% and more preferably at least 15% and most preferably at least 20% of the area of the protective layer.

In a further preferred embodiment of the present invention, the protective layer can be applied in the form of a lacquer layer by means of a printing method, preferably with a digital printing method, for example with an inkjet printing method. This results in the possibility that the structuring of the lacquer layer is formed in the form of an individualizing security feature, since the digital printing process has the flexibility required for this purpose. Since the individualizing security feature according to the present invention is preferably also produced with a digital printing method, the protective layer can, if it is applied in the form of a lacquer layer by means of a digital printing method, be produced and structured with the same printing device, with which also the individualizing security feature according to the present Invention is generated. This achieves a very efficient individualization of the value or security product.

To produce an individualizing structuring of the protective layer in the form of an image representation, an electronically stored original can be rastered and converted into a halftone image. The bright and dark areas of the halftone image can be formed as elevations or depressions in the protective layer. In the case of a halftone image with two gray values (black / white), these gray values can be converted into two different levels of the protective layer surface (thicknesses of the protective layer). In the case of a halftone image with more than two gray levels, for example four gray levels (black / dark gray / light gray / white), the protective layer surface can be formed with a corresponding number of levels. For example, such a relief can be optically scanned and reproduce the original halftone image in a reproduction. Therefore, this structuring can also be designed as a complex and difficult-to-adjust security feature.

For the production of relief-like structured protective layers, printable inks / inks can be applied several times onto the surface to be printed with an ink-jet printing process, so that the laterally differently thick layer regions are formed. For this purpose, suitable printing inks / inks are available, for example the in EP 2 161 313 B1 described UV curable phase change inks.

1. (i) der Produktkörper wird mit dem mindestens einen nichtindividualisierenden Sicherheitsdruck in einer zentralen Fertigungsstätte hergestellt;
2. (ii) der mit dem mindestens einen nichtindividualisierenden Sicherheitsdruck versehene Produktkörper wird dann zu einer dezentralen Fertigungsstätte überführt; und
3. (iii) das mindestens eine individualisierende Sicherheitsmerkmal wird in der dezentralen Fertigungsstätte auf den mit dem mindestens einen nichtindividualisierenden Sicherheitsdruck bedruckten Produktkörper aufgedruckt.

While the product body is produced with the at least one non-individualizing security print on the at least one outer side, preferably in a central manufacturing facility, the individualizing security feature and optionally the protective layer are produced in a decentralized production facility, for example in a dispensing location for security documents. Thus, the additional additional process steps result for the production of the value or security product:

1. (i) the product body is manufactured with the at least one non-individualizing security print in a central manufacturing facility;
2. (ii) the product body provided with the at least one non-individualizing security print is then transferred to a decentralized manufacturing facility; and
3. (iii) the at least one individualizing security feature is printed in the decentralized production facility on the product body printed with the at least one non-individualizing security print.

Thus, the product body produced in the central manufacturing facility is a not yet individualized blank. Such blanks can be produced in large numbers in identical form. For customization, these blanks are transferred to the decentralized manufacturing facilities and there customized by attaching the individualizing security feature.

In the figures, like reference numerals designate elements having the same function or like elements.

The value or security product 100 according to the invention can in particular be a value or security document, for example an identification card. A schematic cross-sectional view through such a card is shown in FIG Fig. 1 shown. This view is not to scale. The card 100 is formed of a product / document body 150. The product body is in Fig. 2 is reproduced, and a cutout on the surface of the product body is in Fig. 2A shown. The card 100 is manufactured from the document body.

The document body 150 in the present example is made of a core 110 formed by laminating multiple layers (not shown) and two overlay plies 120. Both the film layers of the core and those of the overlay layers preferably consist of a polycarbonate, for example bisphenol A polycarbonate. The layers of which the core is made are preferably opaque and, for example, colored with a white pigment. The two overlay layers, however, are unfilled and therefore transparent. On both outer sides 115 of the core design prints 118 are applied over the entire surface, such as guilloches. For this purpose, a customary used for the roll offset ink / ink was used. On both outer sides 125 of the overlay layers prints in the form of a security print 128 are printed, for example also in the form of guilloches. For this purpose, for example, a web offset printing method was used.

The document body 150 is made by laminating. For this purpose, the films of the core 110 and the films for the overlay layers 120 are first provided with the respective prints, namely the design print 118 and the security print 128. Subsequently, the films of the core and the films for the overlay layers are assembled into a stack and arranged between laminating. In addition, to prevent external security printing from contaminating the lamination sheets, release liners of, for example, Pacothane (acrylate-epoxy modified polyester from Pacothane Technologies, U.S.A.) are interposed between the lamination sheets and the outer sheets for the overlay plies (not shown). This stack is then subjected to conventional lamination conditions (in a hot / cold laminating press, for example in a first step at 170 ° C to 200 ° C and a pressure of 50 N / cm ² to 600 N / cm ² and in a second step under cooling at room temperature and under the same pressure) to form a laminate.

The blank thus obtained is not yet individualized or personalized and can therefore be produced in a central production site.

Subsequently, the document body (blank) 150 is printed with an individualizing security feature 200, for example the facial image of the person to whom the document is to be assigned. For this purpose, the blank can first be transported to a decentralized production facility where this production step is undertaken. The individualizing security feature should be multi-colored to meet the requirements for high-quality authentication of the security document. For its production printing inks / inks are printed in the central manufacturing plant in the form of a facial image on both sides of the blank. The printing ink / ink contains, for example, a polycarbonate binder based on a geminally disubstituted dihydroxydiphenylcycloalkane. A typical composition for such ink / ink is in DE 10 2007 052 947 A1 described. This ink / ink may contain pigments or dyes that are visible when illuminated with white light. The ink / ink may alternatively or additionally also contain a fluorescent dye which, for example, is not visible when illuminated with white light, but is visually detectable when illuminated with a UV light source, for example at 365 nm wavelength. By printing with this ink / ink in the form of the face image, the blank is personalized, whereby the value or security document is produced.

To produce the facial image of the blank 150 is heated to a temperature of about 70 ° C by this rests flat on a heated surface. The heated blank is then printed with the ink / ink, for example, multi-colored with an inkjet printing process. This method is flexible, so that from blank to blank different print motifs (facial images 200) can be imprinted on the blanks. The print layers for producing the facial images, like the security print 128, are printed on the outsides 125 of the blank so that both prints lie in the same print plane 126. In addition, both prints are printed overlapping each other.

In Fig. 2A the superimposition of the non-individualizing security print 128 by the individualizing security feature 200 is shown in a cross-sectional view: the individualizing security feature is printed on the surface 125 of the product body 150 already printed with the non-individualizing security print. For this purpose, the For this purpose used ink / ink of the individualizing security feature, for example, be printed with an inkjet printing process. This ink penetrates, in particular diffuses, into the surface of the material of the product body and also coats the pre-existing ink of the non-individualizing security print.

To protect the document against mechanical or environmental influences, protective layers 300 are additionally applied to the outer sides 125 of the blank 150 and thus to the security print 128 and the facial images 200. These protective layers are formed, for example, by lacquer layers which, like the facial images, can be produced by means of ink jet printing. These paint layers are also structured (in Fig. 1 only indicated schematically). In the present case, the structuring 310 of the two lacquer layers in the form of the facial image is formed by producing the facial image representing dark image parts (generated from halftone halftone images) in the form of thickened (or alternatively thinner) locations in the lacquer layers.

The facial image 200 and the protective layers 300 may preferably be applied to the blank 150 in a remote manufacturing facility. For this purpose, non-personalized blanks from the central manufacturing facility in the decentralized manufacturing facilities, such as issuing points for the value or security documents, transported. There, the personalizing security print layer and the protective layer can be printed on the blank.

The personalizing security print layers 200 can not be manipulated without necessarily being noticed. For if it is attempted to remove the personalizing security printing layer (personalizing security feature), for example by means of a chemical solvent, so that another security feature, for example the face image of another person, can subsequently be attached, the one in contact with the security printing layer will also be in contact Security pressure 128 attacked. In Fig. 3 Examples of such manipulation attempts are shown:
In 3a, 3b views of identification cards 100 are shown, each having a passport photograph 200 as an individualizing security feature and a security print 128 overlapping therewith.

Starting from the polycarbonate card 100 and the polycarbonate-based ink / ink for the facial image in the passport photo 200, an attempt is made to remove the ink / ink of the passport photo with acetone for the purpose of manipulation. It turns out that it is inevitable that the printing ink / ink of the security print 128 is removed. This is readily apparent. In the Fig. 3a, 3b the positions are indicated by arrows (x) on which such attempts to remove the ink / ink have been made. In these areas, along with the ink / ink of the passport photo, the ink / ink of the security print is also removed, so that tampering becomes obvious.

In Fig. 4 another embodiment of the present invention is shown:
The product body formed by the core 110 and overlay layers 120 is as in FIG Fig. 2 constructed and has on the outer sides 125 on a non-individualizing security printing 128, such as guilloches on. In addition, an individualizing security feature 200, in the present case a serial number, for example by means of a numbering device is printed on the outside in accordance with the invention. In addition, located in the product body between the overlay layer 120 and the core 110, a design pressure 118, which may also be formed in the form of guilloches.

Unlike the in Fig. 2 In the embodiment shown, non-individualizing security print 128 and design print 118 are each in the form of the same tag 180, in the form of the word representation 'VOID'. For this purpose, both prints 118, 128 each have free areas and pressure areas which are designated by the reference numbers 160, 170 ( Fig. 4a ). When the product body is viewed perpendicular to the outer side 125 of the product body, ie parallel to the surface normal 190, the free areas of the non-individualizing security print are exactly, ie register-accurate, over the print areas of the design print (in the areas 160) and the print areas of the non-individualized security print exactly over the free areas of the print shop Design print (in the ranges 170). As the outdoor areas and printing areas of both prints have the same shape, size and arrangement, they are complementary to each other. The registration accuracy of both prints is achieved by exact lateral and angular alignment.

As long as the non-individualizing security print 128 is undamaged, both prints 118, 128 complement each other so that the security feature 180 is imperceptible to a viewer ( Fig. 4b ). Only when the non-individualizing security printing is damaged, the security indicator becomes visible ( Fig. 4c : complete removal of non-individualizing security printing). In the present case, a part of the individualizing security feature 200 has also been removed together with the non-individualizing security print, specifically the number '0'. This is the result of the overlap of the non-individualizing security print and the individualizing security feature in the same print layer 126.
