Description

Valuable or secure products and methods for making valuable or secure products using decentralized personalization product method

technical field

The invention relates to a value or security product having a product body with two outer sides. The product is usually equipped with at least one non-personalized security imprint and at least one personalized security feature. Furthermore, the invention also relates to a method for manufacturing said valuable or safe product.

Background technique

Value or security products, in particular value or security documents, are used to verify the identity of individuals, especially when crossing national borders, or to verify facts or claims such as payment or delivery of a product or provision of a service. This ensures that the product cannot, or can only be imitated, counterfeited or falsified with great effort. The product thus contains security features whose counterfeiting is extremely difficult or indeed impossible. For example, said products, such as banknotes, consist of materials that are not readily available. Additionally or alternatively, the security features may be implemented with specific inks such as luminescent or optically variable inks, optical elements such as holograms, oblique images, dynamic graphic objects, focusing arrays or refractive arrays, additionally (with visible inks/inks or Luminous ink/ink's) guilloche, speckled fibers, security threads and others.

A security feature used in a value or security product, in particular a value or security document, can only be used to prove the authenticity of the document independently of the type of the security feature or the user of the security feature. Personalized, e.g. personalized security features also contain information about the type of document, about the user of this document and/or about the object uniquely assigned to the document in coded form or also in the form of an identifiable mark . The information may be the user's profile picture (photo), the user's personal data such as name, date of birth, place of birth, address or personal logo such as membership number, or the user's signature. Further security features that personalize a value or security product can be, for example, the product serial number or the chassis number of the motor vehicle assigned to the product.

The identification document is generally first produced in the form of a non-individualized blank (product body). This part of the production is typically carried out in a central production station, since the blanks can be produced indistinguishably from one another and thus in series production. Personalization of the blank, for example personalization, can also be carried out in the central production by, for example, placing in the document the name, address, date of birth and place of birth of the document holder, as well as a portrait. However, carrying out the processing steps in a central production station is disadvantageous in terms of production availability. For this reason, the personalization of the documents is preferably performed decentralized, so that rapid processing can be ensured, for example at the point of issue of the value or security document.

As a rule, security features and in particular personalization data should be accommodated on an integrated surface of a value or security product, since in this way it can be better ensured that the product is less susceptible to tampering attempts:

Laminates consisting of at least three laminate layers are known, for example, from DE 10 2011 006 191 A1, which can be used as value and/or security documents. The laminated body comprises at least two color regions, the color regions are arranged one above the other, and the color regions are respectively located on one of the at least two color planes. The colored areas are preferably printed with printing ink. The color planes are arranged internally in the laminate. It should be pointed out that the integrated arrangement of the color planes in the laminate makes tampering with color layer regions lying on the color planes extremely difficult, since for tampering the color layer regions must be extracted and must be located at least in all The laminate is layered in the area of the color layer described above.

Furthermore, a document with a security stamp is described in DE 10 2008 012 420 A1. The photo information is respectively introduced in several layers of the file, wherein the photo information complements the entire photo. Photo information is produced by the inkjet printing method. It is pointed out that the printing layer is advantageously arranged on the built-in layer of the composite structure. Forgery or falsification of the printed layer used as a security feature is made difficult or even ruled out in this case.

In a decentralized manufacturing station, individual data can be added to the blank only by a specific manufacturing method. For example, personal data can be written into card scrim with the aid of a laser beam (DE-PS 29 07 004 B1).

Personalization of valuable or security products by means of laser engraving, as described in DE-PS 29 07 004 B1, opens up the possibility of generating personalization data on a built-in surface in the product, so that the personalization Data is largely protected against tampering. However, at most the personalization data can be reproduced in black and white by means of the described method. However, it is desirable to reproduce, for example, personalized information in color, such as a profile picture of an individual uniquely assigned to the product, since the color reproduction enables, for example, better identification and a very general A more reliable judgment of authenticity.

Contents of the invention

It is therefore the object of the invention to generate individualization data on value or security products in a decentralized production station, also in color. A color display should be able to be produced at image quality. Tampering (falsifying) the data should therefore not be easily possible. Furthermore, the falsification should be easily visible in order to be able to detect such falsifications on value or security products without problems.

definition:

As long as the concept "valuable or secure product" is used in the description and claims of this application, said valuable or secure product may in particular be a valuable or secure document or a security element, said valuable or secure product is understood For example passports, identity cards, driving licenses, access control documents or other ID cards, vehicle licenses, vehicle factory certificates, visas, cheques, means of payment, especially banknotes, check cards, bank cards, credit or cash payment cards, customer cards , health card, smart card, company certificate, certificate of entitlement, membership card, gift certificate or purchase receipt, manifest or other credential, revenue stamp, postage stamp, admission ticket, chip or other document. A product according to the invention can also be a security element, such as a label, an adhesive label (for example for commodity security), a patch or the like, which security element can have the security features according to the invention and which can An intermediate product or other commodity of the value or security document, for example a commodity to be marked whose authenticity can be guaranteed, is non-detachably connected in order to form the value or security document or said marked commodity. The article can, for example, be a sample of a limited series of objects of the same kind whose uniqueness is indicated by means of a number. Said numbering can be achieved by personalizing the security element provided with the security feature. The value or security product can also eg be a smart card. The value or security document can exist in ID1, ID2, ID3 or some other standardized or non-standardized format, eg in the form of a booklet as in a passport-like object, or eg in the form of a card. A value or security product is generally a laminate consisting of a plurality of document layers which are joined to each other flatly in register precisely under the action of heat and under increased pressure. The products should meet the requirements of standardization, for example according to ISO 10373, ISO/IEC 7810, ISO 14443. The product layer consists, for example, of a substrate material suitable for lamination.

Valuable or safe products may consist of polymers selected from the group consisting of polycarbonate (PC), especially polycarbonate of the bisphenol A type, polyethylene terephthalate Glycol ester (PET), its derivatives such as ethylene glycol modified polyethylene terephthalate (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyethylene Alcohol butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS), polyvinyl phenol (PVP), polypropylene ( PP), polyethylene (PE), thermoplastic elastomer (TPE), especially thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and its derivatives, or the Valuable or secure products may consist of paper or cardboard or glass or metal or ceramics. Furthermore, the product may also be manufactured from a plurality of the materials. It is preferably composed of PC or PC/TPU/PC. The polymers can be present either filled or unfilled. In the latter case of being unfilled, the polymer is preferably transparent or translucent. If the polymer is filled, the polymer is opaque. Preferably, the product is made of 3 to 12 layers of film, preferably 4 to 10 layers of film. The film may also have a printed layer. In any case, according to the invention the security print is present on the outer side of at least one outer film in the laminated value or security product.

Basic feature of the present invention and preferred embodiment:

According to a first aspect of the invention, the aforementioned tasks are solved by a valuable or security product according to the invention. The product of value or security consists of a product body with two outer sides. The value or security product has at least one non-personalized security imprint and at least one personalized security feature. At least one non-personalized security mark and at least one personalized security feature are printed overlappingly on at least one of the outer sides of the product body on the same printing plane.

According to a second aspect of the invention, the aforementioned object is also solved by the method according to the invention for the production of valuable or secure products by decentralized personalization, in particular personalization. The method comprises the following method steps:

(a) manufacturing a product body having two outer sides, wherein at least one non-personalized security imprint is located on at least one of said two outer sides; and

(b) at least one individualized security feature is printed superimposed on the same printing plane at least on the outer side of the product body with at least one non-individualized security imprint, wherein a value or security product is formed.

The value or security product and the method for producing the value or security product according to the invention open up the possibility of producing individual markings in color in a decentralized production station. This is because the product body with the logo on the outside of the product body can be produced without difficulty by conventional techniques in that the logo is printed, for example, in a conventional manner.

Furthermore, counterfeiting of value or security products can be detected without problems by means of the security of value or security products according to the invention. This is achieved by creating a tight connection of the printing ink/ink for the personalized security feature with the printing ink/ink of the non-personalized security imprint, since the security feature and the security imprint are on the same printing plane The upper overlap is located on the outer side of the product body. If a counterfeiter attempts to remove the personalized marking from a value or security product, so that a changed personalized marking can then be installed, then at the same time and said forgery cannot prevent the removal of the non-personalized security stamp as well. Since the security print usually extends over a relatively large area of the surface of the value or security product and also overlaps, for example, further security features here, the security print cannot be replaced at an acceptable cost. As a result, identification of such manipulations of the value or security product by at least partially destroying the security stamp can be maintained.

A further advantage of the invention is that the value or security product can be produced with a small thickness, in particular in the form of a thin card, because for at least one individualized security feature and at least one non-identical Only a foil is necessary for the individual security stamp.

The personalized security feature may be any usual sign for personalizing, in particular personalizing, a valuable or security product, for example a record of personal data of the document holder such as the document holder's name, date of birth and Place of birth, residential address or fixed number, or serial number of a document or another identification mark. The data may be described, for example, in alphanumeric characters. In addition, individualized security features can be formed by biometric data, such as fingerprints, portraits, handprint structures, irises or retinas, or by an own handwritten reproduction (signature) of the cardholder's name. Biometric data as well as signatures can all be reproduced graphically.

A non-personalized security imprint may be constituted by any pattern or any other reproduction of a non-personalized representation of a value or security product, for example by guilloche, patchwork, carpet or fabric patterns, The image reproduction or other graphic structure composition of artworks.

Either both the at least one personalized security feature and the at least one non-personalized security print can be applied only to one outer side of the product body, or the at least one personalized security feature and the at least one non-personalized security print can each be located on On both outer sides of the product body.

Both non-personalized security prints and personalized security features can be formed by printing inks/inks which produce a visually recognizable printed image. Furthermore, the printing inks/inks used for this contain suitable pigments and/or pigments which absorb in the visible spectral range. Such pigments and pigments are generally known and common in the art. Alternatively or additionally, the printing inks/inks can also contain luminescence pigments and/or luminescence pigments (luminescence=fluorescence, phosphorescence), which in turn absorb in the visible spectral range and are thus also visually visible. Recognize, and/or not absorb in the visible spectral range, but absorb for this purpose in another spectral range, for example in the IR or UV spectral range. The latter pigments and pigments can emit, for example, in the visible spectral range, so that they fluoresce visually recognizable after excitation by electromagnetic radiation, for example, in the IR or UV spectral range. The printing inks/inks for the at least one personalized security feature and the at least one non-personalized security imprint can be different with respect to the aforementioned alternatives.

In a preferred embodiment of the invention, at least one individualized security feature is printed with a polycarbonate-based printing ink/ink. Thus, the printing ink/ink contains a binder composed of polycarbonate. The advantage achieved by using the printing ink/ink is that, in particular when the material of the product body is also composed of polycarbonate or contains polycarbonate at least on its outer side, the printing ink/ink is firmly connected to the on the outside of the product body and thus cannot be easily removed. In principle, all common polycarbonate materials are conceivable as polycarbonate binders, for example polycarbonates obtained using bisphenol A. The following polycarbonates are particularly preferred as binders for printing inks/inks in the presence of disubstituted dihydroxydiphenylcycloalkanes, preferably monomers such as 4,4'-(3 ,3,5-trimethylcyclohexane-1,1-substituent) dihydric phenol, 4,4'-(3,3-dimethylcyclohexane-1,1-substituent) dihydric phenol or obtained in the case of 4,4'-(2,4,4-trimethylcyclopentane-1,1-substituent) dihydric phenol. Said polycarbonates are described in DE 10 2007 052 947 A1 (part A there). The disclosure content of this publication at least with regard to the raw materials and production conditions for polycarbonates is hereby incorporated by reference into the present application document.

In a further preferred embodiment of the invention, the product body consists of polycarbonate or contains polycarbonate on at least this or all outer sides on which at least one non-personalized security stamp and at least one personalized security feature are imprinted. ester. Of course, the entire product body can be made of polycarbonate or contain polycarbonate. However, it is sufficient according to the invention for this purpose if only the outer side consists of polycarbonate or at least contains polycarbonate. For example, only the film layer arranged on the outer side of the laminated product body can consist of polycarbonate or at least contain polycarbonate. Alternatively, further film layers arranged between the outer film layers can also consist of polycarbonate or at least contain polycarbonate. By using a polycarbonate-containing outer side, at least on the outer side on which at least one non-personalized security imprint and at least one personalized security feature are arranged, a printing ink/ink for forming a personalized security feature and a product body are produced stronger connections. This is especially true when the printing ink/ink for forming the individual security feature is based on polycarbonate in the manner described above.

In yet another preferred embodiment of the invention, at least one individual security feature is introduced into the outer side of the product body, for example by diffusion. This measure achieves that the printing ink/ink of the personalized security feature can be detached less easily than a non-personalized security imprint. If there is thus an attempt to falsify a product of value or security, at least the security imprint arranged there is destroyed before the individualized marking is removed.

In order that the printing ink/ink of the personalized security feature can enter into the outside of the product body, the printing ink/ink can be matched to the material of the outside on which the printing ink/ink is printed.

In a preferred refinement of the invention, the possibility of such an adaptation consists in selecting similar chemical materials for the printing ink/ink on the one hand and for the product body on the other hand, i.e. each at least essentially consisting of the same polymer Material. Particularly very preferably, both the printing ink/ink and the material on the outside of the product body consist of polycarbonate or contain polycarbonate.

According to a further refinement of the invention, an alternative or additional possibility of this mutual adaptation of the materials consists in selecting the composition of the printing ink/ink in such a way that the printing ink/ink contains the same The material on the outside of the product body is compatible with solvents. The solvent presumably has the effect of dissolving the material on the outside of the product body so that the printing ink/ink can penetrate into said material. For polycarbonate-based adhesives, suitable solvents are described in DE 10 2007 052 947 A1 (part B there). The disclosure content of this publication at least with regard to solvents for ink formulations is hereby incorporated by reference into the present application document.

In order to allow printing ink/ink for at least one individualized security feature to penetrate, in particular diffuse, into the outer side of the product body, according to a further development of the invention, it can also be provided additionally or alternatively that the product body is printed with the individuality During the safety feature of tl (method step (b)) is heated to a temperature higher than room temperature, for example a temperature of at least 40°C, more preferably at least 50°C, even more preferably at least 60°C and even more preferably at least 65°C. The maximum temperature, which is related to the type and composition of the product body and the printing ink/ink, should not be exceeded in order to avoid deformation, excessive expansion or other adverse effects of the material of the product body under the action of heat. Thus, 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, still more preferably not more than 90°C and most preferably not more than 80°C. In the case of excessively high temperatures there is the danger that the positional accuracy of the print can no longer be ensured. Therefore, the product body is most preferably heated to about 70° C. when printing the at least one personalized security feature.

In a further preferred embodiment of the invention, the non-personalized security imprint extends over the entire outer side of the product body. Alternatively, the non-individualized security stamp can also cover only a partial area of the outer side of the product body, for example over a maximum of 25%, further preferably of a maximum of 50% and most preferably of a maximum of 75% of the surface area. Said face coverage is preferably at least 10% and further preferably at least 15% and most preferably at least 20%. This ground extension, preferably over the entire surface of at least one outer side of the product body, makes it possible, if not impossible, to reconstruct the non-personalized security feature after the non-personalized security feature has been damaged by tampering. is extremely difficult.

According to yet another preferred embodiment of the invention, when the non-individualized security imprint extends on the outer side of the product body to an area in which an additional security feature of the value or security product is located, namely Such reconfiguration is particularly difficult when the non-personalized security imprint overlaps the further security feature, and it is still further preferred that the further security feature is also provided with a non-personalized security feature. Imprinted valuable or security products are also arranged on the same plane. Because in this case the additional security features are also compromised when the non-personalized security imprint is reconstructed. It is further preferred that the further security feature is likewise a printed feature. Most preferably, the further security feature is a printed feature arranged on a printed plane like a non-personalized security imprint.

In a further preferred embodiment of the invention, the non-personalized security stamp can first be printed on the film which is intended to be laminated to manufacture the product body, rather than on the finished laminated product body on at least one outer side of the . The processing method described offers the advantage of easier processing in printing technology, since the film can be easily processed in the roll-to-roll method, whereas the laminate is only available piece by piece and thus cannot be produced continuously in print. Furthermore, the laminate is less flexible due to its greater thickness and thus cannot be processed without problems by conventional printing methods.

Conventional printing methods, such as offset printing, flexographic printing and screen printing, can be used to produce the at least one non-personalized security stamp. Preferably a web offset printing method is used.

In addition to the non-individualized security print and the individualized security features printed on at least one outer side of the product body, the laminate can also have a printed layer on the face embedded in the laminate. The built-in print layer is printed onto the films prior to lamination, and the films are then laminated to each other. The integrated printing layer can likewise be produced by conventional printing inks/inks, just like the non-personalized security imprint and the personalized security feature. In this case the printing inks/inks also contain suitable pigments and/or pigments which absorb in the visible spectral range and are generally known and common in the technical field. Alternatively or additionally, the printing inks/inks may also contain luminescent pigments and/or luminescent pigments, which may have the spectral properties.

In a further preferred embodiment of the invention, at least one integrated design imprint can also be provided as a printed layer. At least one design imprint and at least one non-individualized security imprint are arranged precisely and complementary to each other in the form of at least one security feature in the preferred refinement, so that at least one security feature due to tampering with the valuable Or security products can only be identified, and only exist hidden in the absence of tampering, that is, invisible. For this purpose, the design imprint forms a negative side relative to the non-personalized security imprint or vice versa. Thus, the free area in the design imprint touches the printed area in the non-personalized security imprint, and the free area in the non-personalized security imprint touches the printed area in the design imprint, that is, the difference between the two imprints The free area and the printed area are preferably placed one above the other in precise register when viewing the value or security product vertically. Alternatively, the free or printed areas of the two imprints can also be at an angle determined relative to the surface normal of the value or security product, for example at an angle in the range of greater than 0° to 80° relative to the surface normal Complementary under the observation that the security feature is invisible (hidden) when the non-personalized security imprint is not damaged, whereas when the non-personalized security imprint is at least partially removed due to tampering, then becomes visible, so that then only the part of the security marking which consists of the design imprint becomes recognizable. The design inscription can be formed in the form of a security inscription, for example in the form of a guilloche.

In a further preferred embodiment of the invention, in order to prevent the non-personalized security imprint on the outside of the film stack provided for lamination from contaminating the laminate during lamination, a A separation layer is arranged between the non-personalized security imprints provided. The separating layer can be formed, for example, by a film of polyimide, polyethylene, polyethylene terephthalate or epoxy acrylate resin-modified polyester. This film is not connected to the outer sides of the product body and can therefore be removed again after lamination.

For lamination, a plurality of stacked films are processed, for example, either simultaneously in a multilayer press or one after the other in a continuous system with the application of pressure and input of heat. Especially when the film consists of polycarbonate, then the lamination is typically in a hot/cold lamination press in a first step at 170°C to 200°C and 50N/ ^cm2 to 600N/ ^cm2 and at the same pressure in the second step with cooling to about room temperature.

Since the laminate is preferably produced in the form of overlapping active parts (card, sheet, page), the individual active parts are obtained from the overlapping active parts by separation after lamination. For this purpose punching methods can be used, for example. A single payload has a desired specification, for example ID1, ID2 or ID3 according to ISO/IEC7810.

In order to produce at least one individualized security feature, printing by digital printing methods (non-impact-printing methods) consumes printing inks, since this method provides the required flexibility for the purpose of personalization. Inkjet printing methods (Inkjet printing methods) are especially highly preferred because the printing inks required to achieve the desired print quality are provided by this method. All available inkjet printing methods and inkjet printing devices (presses) available for this purpose can be used for producing individual security features, for example drop-on-demand and continuous inkjet methods. Suitable polycarbonate-based printing inks are described, for example, in DE 10 2007 052 947 A1. The disclosure content of this publication at least with regard to the components formulated as inks, the raw materials and production conditions of the inks required for this purpose is hereby incorporated by reference into the present application documents.

Since the personalized security feature is produced on the same plane and overlapping with the non-personalized security imprint and is printed onto at least one outer side of the product body, the printed ink/ink for the personalized security feature comes into contact with The area on the outside in which the printing ink/ink of the non-personalized security imprint has been located. The printing ink/ink level for the personalized security feature lays on the solidified printing ink/ink of the non-personalized security imprint and enters, in particular diffuses, into the material on the outside of the product body, solidified non-personalization Chromized printing ink/ink is located on the outside. As a result, the solidified printing ink/ink of the non-personalized security signature is surrounded almost completely by the printing ink/ink of the personalized security feature. This configuration ensures that the individualized security feature is protected against forgery, since the tight penetration of the printing ink/ink through the two security features makes it impossible to falsify the individualized security feature in isolation. Immediately visible is tampering, if necessary after excitation (for example by 365 nm radiation), otherwise visually invisible printing inks/inks in the visible spectral range.

After separation into individual effective parts, the resulting laminate can be finally coated on one or both sides with a protective layer, for example with a protective lacquer or topcoat or with a film. The film may in particular be a patch, a hologram, a dynamic graphic element or a scratch-resistant film. The protective layer thus constituted protects the underlying security features, gives the document the required abrasion resistance and protects said security features from scratches and other damage as well as from the environment, such as moisture and chemicals, thereby effectively Valuable or safe products have long-term stability, eg according to ICAO requirements. For this purpose, in a preferred embodiment of the invention at least the outer side of the value or security product which has the non-personalized security imprint and the personalized security features is coated with a protective layer.

The protective lacquer or topcoat can consist of UV-curing printing inks/inks based, for example, on acrylic resins, which are optionally filled with nanopigments to increase the scratch resistance. The protective varnish or topcoat is preferably transparent, but at least translucent and in any case so light-transmissive that non-personalized security imprints and personalization located underneath the protective varnish or topcoat The security features are visually visible. The protective layer preferably covers at least the area occupied by the individualized security feature on at least one outer side of the value or security product. Particularly preferably, the protective layer extends over at least one outer surface that is larger than the area occupied by the at least one individualized security feature, ie preferably a maximum of 25% of the corresponding outer surface of the product of value or security. %, more preferably a maximum of 50% and still more preferably a maximum of 75% of the surface extension. Said face covering is at least 10% and further preferably at least 15% and most preferably at least 20% of the respective outer side of the value or safety product. Most preferably, the protective layer completely covers at least one outer side of the product of value or security, wherein it is further preferred that the two outer sides are completely coated with the protective layer.

In a preferred embodiment of the invention, the protective layer is structured. For example, according to a predetermined (lateral, ie running parallel to the outside of the product body) structure, the protective layer can have regions that are thinner or alternatively thicker than the remaining regions of the protective layer. Furthermore, either the already produced protective layer is structured (either by further application of the varnish material or by partial removal of the protective layer) or the protective layer is applied to the outside in a structured manner.

The structuring of the protective layer can be embodied in the form of individualized or non-individualized markings. In a preferred embodiment of the invention, the structuring is formed in the form of an individual security feature, for example in the form of a biometric feature of the owner of the value or security product. Alternatively or additionally, the structuring can also be formed in the form of a non-individualized symbol, for example in the form of an icon. Particularly preferably, the structuring is formed in the form of a feature that is already present on the value or security product in another form, for example by means of the individual security feature according to the invention. The two security features (the individualized security feature according to the invention and the individualized structuring of the protective layer) can be arranged on the outside in overlapping regions or in regions that do not overlap one another. Alternatively, the two security features can also be arranged one above the other in precise register.

The structuring can extend over the entire surface of the protective layer or only over a part of the surface, for example over a maximum of 25%, further preferably a maximum of 50% and most preferably a maximum of 75% of the surface. The area coverage of the structured features in the protective layer is at least 10% and further preferably at least 15% and most preferably at least 20% of the area of the protective layer.

In a further preferred embodiment of the invention, the protective layer can be applied in the form of a lacquer layer by means of printing methods, preferably digital printing methods, for example inkjet printing methods. This enables the possibility of structuring the lacquer layer in the form of individual security features, since the digital printing method has the flexibility required for this. Since the personalized security features according to the invention are also preferably produced by digital printing methods, when the protective layer is applied in the form of a lacquer layer by means of digital printing methods, the protective layer can then be produced by the same printing device and hereby Being structured, the same printing unit also produces the individual security features according to the invention. This enables a very efficient personalization of valuable or secure products.

In order to produce the individual structuring of the protective layer in the illustrated form, the electronically stored original can be textured and converted into continuous tone. The shallow and deep regions of the sequential tone can be configured as protrusions and depressions of the protective layer. In the case of contone with two grayscale values (black/white), said grayscale values can be converted into two different levels of the surface of the protective layer (thickness of the protective layer). In the case of continuous tone with more than two grayscale values, for example four grayscale values (black/dark gray/light gray/white), the protective layer surface is configured with a corresponding number of levels. Formal structures of this type can be scanned, for example optically, and the original continuous mapping can be reproduced in reproduction. As a result, the structuring can also be designed as a complex and hardly adjustable security feature.

In order to produce a protective layer in the form of a structured structure, printing inks that can be printed by means of inkjet printing methods can be applied to the surface to be printed multiple times, so that layer regions of different lateral thicknesses are produced. Suitable printing inks/inks are available for this purpose, for example the UV-curable phase transition inks described in EP 2 161 313 B1.

The product bodies with at least one non-individualized security stamp on at least one outer side of the product bodies are preferably produced in a central production station, whereas they are produced in a decentralized production station, for example at the issuing place of the value or security document Personalized security features and layers of protection where necessary. The following additional further method steps are thus carried out for producing a valuable or safe product:

(i) manufacture in a central manufacturing station a product body with at least one non-personalized security imprint;

(ii) subsequently transferring the product body provided with at least one non-personalized security stamp to a decentralized manufacturing station; and

(iii) Printing at least one individualized security feature in a decentralized manufacturing station onto a product body already imprinted with at least one non-individualized security stamp.

The product bodies produced at the central production station are thus blanks which have not yet been individualized. The blanks can be manufactured in large numbers in the same form. For the individualization, the blanks are transferred to a decentralized production station, where they are individualized by applying individual security features.

The value or security product 100 according to the invention may in particular be a value or security document, for example an identification card. A schematic cross-sectional view of such a card is shown in FIG. 1 . The views are not to scale. The card 100 consists of a product/document body 150 . The product body is depicted in Figure 2 and a partial view on the upper surface of the product body is shown in Figure 2A. The card 100 is manufactured starting from the document body.

The document body 150 is produced in the present example from a core 110 , which is generally composed of several layers (not shown), and two covering layers 120 . Both the film layer of the inner core and the covering layer preferably consist of polycarbonate, for example bisphenol A polycarbonate. The layer forming the inner core is preferably opaque and for this purpose is colored, for example, with white pigment. However, the two cover layers are not filled and are therefore transparent. A design imprint 118 , for example guilloche, is applied all over to the two outer sides 115 of the inner core. For this purpose printing inks/inks are used which are customary, for example, for web offset printing. An inscription in the form of a security stamp 128 is printed, for example likewise in the form of a guilloche, onto the two outer sides 125 of the cover layer. For this purpose likewise the web offset printing method is used, for example.

The document body 150 is manufactured by lamination. To this end, the film of the inner core 110 and the film for the cover layer 120 are firstly provided with corresponding inscriptions, namely the design inscription 118 and the security inscription 128 . Next, the films for the inner core and the films for the cover layer are stacked into a stack and arranged between the laminates. In order that the external security print does not contaminate the laminate, a separation layer is additionally arranged between the laminate and an external film (not shown) for the cover layer, for example made of a release film (release film technology of epoxy acrylate resin modified polyester, USA). The stack is then subjected to normal lamination conditions (in a hot/cold lamination press, for example at 170° C. to 200° C. and a pressure of 50 N/cm ² to 600 N/cm ² in the first step and in the second step The laminate is joined in two steps with cooling to about room temperature and under the same pressure).

The blanks obtained in this way have not yet been individualized or individualized and can thus be produced in the central production station.

Subsequently, a personalized security feature 200 is printed on the document body (blank) 150 , for example a personal portrait which is to be assigned to the document. For this purpose, the blanks can first be transported to a decentralized production station, where the production steps are carried out. The individual security features should be in color, thereby meeting the requirements for high-quality certification of security documents. To manufacture the security document, printing ink/ink is printed on both sides of the blank in the form of a head portrait at a central manufacturing station. Printing inks/inks comprise for example polycarbonate binders based on disubstituted dihydroxydiphenylcycloalkanes. Typical compositions of such printing inks/inks are described in DE 10 2007 052 947 A1. The printing inks/inks may contain pigments and pigments which are visible under illumination with white light. The printing inks/inks may alternatively or additionally also contain fluorescent pigments, which, although not visually recognizable, for example, when irradiated with white light, appear in the visually identifiable. The blank is personalized by printing with said printing ink in the form of a portrait, wherein a value or security document is produced.

To produce the large head, the blank 150 is heated to a temperature of approximately 70° C. by laying it flat on a heated base plate. The heated blank is then printed, for example in color, with printing inks by means of an inkjet printing method. The method is flexible so that a blank-to-blank different printing theme (major portrait 200) can be printed onto the blank. The printing layer for producing the head portrait is printed on the outer side 125 of the blank as is the security stamp 128 , so that both stamps lie on the same printing plane 126 . Furthermore, the two prints are printed on top of each other.

In FIG. 2A the overlapping of the non-personalized security stamp 128 through the personalized security feature 200 is shown in cross-section: the personalized security feature is printed onto the product body 150 that has been imprinted with the non-personalized security stamp. on the surface 125 . Furthermore, the printing inks/inks used for this purpose can be imprinted with individualized security features, for example by means of inkjet printing methods. This printing ink/ink penetrates, in particular diffuses, into the surface of the material of the product body and also coats the already existing printing ink/ink of the non-personalized security stamp.

If the document is to be additionally protected against mechanical or environmental influences, a protective layer 300 can also be applied to the outer side 125 of the blank 150 and thus to the security print 128 and the mugshot 200 . The protective layer consists, for example, of a lacquer layer which is also produced like a portrait by inkjet printing. Furthermore, the paint layer is structured (shown only schematically in FIG. 1 ). In this case, the structuring 310 of the two paint layers is structured in the form of a portrait, in that the dark image parts representing the portrait (produced by the textured continuum) are formed with a thickened ( Or alternatively thinner) the form of the site is produced in the paint layer.

The portrait 200 and the protective layer 300 can preferably be applied to the blank 150 in a decentralized manufacturing station. For this purpose, the unpersonalized blanks are transported from the central production station to a decentralized production station, for example for the issuance of value or security documents. There, individual security prints and protective layers can be printed onto the blanks.

The personalized security print layer 200 cannot be tampered with necessarily without being detected. Because when attempting to remove the personalized security print layer (personalized security feature), for example by means of chemical solvents, so that other security features can then be placed, such as another person's head portrait, then also act on the security. The security imprint 128 of the printed layer contacts. An example of such a tampering attempt is shown in Figure 3:

FIGS. 3a, 3b show views of identification cards 100 each having a passport photograph 200 as an individualized security feature and a security imprint 128 superimposed on the individualized security feature.

Based on the card 100 made of polycarbonate and the polycarbonate-based printing ink/ink for the portrait in the passport photo 200 , the passport photo printing ink/ink is removed with acetone for the purpose of tampering. It has been shown here that it is unavoidable that the printing ink/ink of the security print 128 is also removed. This can be easily identified. In FIGS. 3 a , 3 b , arrows (x) mark the points at which such an attempt to remove the printing ink/ink takes place. The printing ink/ink of the security stamp is also removed together with the printing ink/ink of the passport photo in said area, so that said tampering becomes apparent.

A further embodiment of the invention is shown in FIG. 4:

The product body consisting of inner core 110 and cover layer 120 is constructed as in FIG. 2 and has a non-individualized security imprint 128 , for example guilloche, on the outer side 125 . Furthermore, an individualized security feature 200 , in this case a serial number, is printed on the outer side, for example by means of a numbering device, in a manner according to the invention. Furthermore, a design imprint 118 is located in the product body between the cover layer 120 and the inner core 110 , said design imprint 118 , which can likewise be configured in the form of a guilloche.

In contrast to the embodiment shown in FIG. 2 , non-personalized security imprint 128 and design imprint 118 are each produced in the form of the same logo 180 , ie in the form of the text "VOID". For this purpose, the two markings 118 , 128 each have a free area and a printed area, which are designated with reference numerals 160 , 170 ( FIG. 4 a ). When the product body is viewed perpendicular to the outer side 125 of the product body, i.e. parallel to the normal 190 of the face, the free area of the non-individualized security imprint is located exactly above the printed area of the design imprint (in the area 160 middle), and the printing area of the non-personalized security stamp is located exactly above the free area of the design stamp (in area 170). Since the free and printed areas of the two imprints have the same shape, size and arrangement, the free and printed areas of the two imprints complement each other. The precision of matching of the two prints to one another is achieved by the exact angular orientation of the sides.

As long as the non-personalized security stamp 128 is not damaged, the two stamps 118 , 128 complement each other so that the security feature 180 is not perceptible to a viewer ( FIG. 4 b ). Only when the non-personalized security imprint is damaged, the security emblem can be recognized (Fig. 4c: non-personalized security imprint completely removed). In this case, a part of the personalized security feature 200 , ie the number "0", is also removed together with the non-personalized security imprint. This is the result of the overlapping of the non-personalized security imprint and the personalized security feature in the same printing plane 126 .
