Definitions
- the invention relates to a method for producing an individualized security document and to a method for producing an individualizable security document blank.
- the invention relates to a method for producing an individualized security document, wherein a colored, particularly preferably full-color customization information is introduced into a security document, and a method for producing a security document blank, which is color customizable.
- security documents with information which are individually associated with the respective security document.
- Such individual information which is also referred to as customization information, is, for example, a serial number of a document.
- customization information is, for example, a serial number of a document.
- the personalization information includes a name, a first name, a date of birth, a place of residence, information on biometric features such as a height, an eye color, or a fingerprint pattern or a face image to list some personalization features.
- Security documents are considered to be documents which have at least one feature which makes copying, duplicating and / or falsifying or the like considerably more difficult or impossible.
- Security documents include, for example, passports, identity cards, identity cards, access cards, driver's licenses, visas, credit cards, postage stamps, securities, but also security-enhanced tickets, seals of authenticity or counterfeit-protected packaging, to enumerate some by way of example. Common to all is that they include at least one, usually several security features or security elements that make it difficult or impossible falsification, imitation, duplication and / or unauthorized production.
- a portable data carrier such as a smart card known in which a security feature by introducing recesses, Filling the recesses is produced with a translucent material and curing of the translucent material, wherein the translucent material contains constituents that can be excited by luminescence and UV or IR irradiation.
- the DE 10 2010 023 218 A1 describes a method for producing a security document with a watermark.
- a plurality of recesses are introduced, which do not completely penetrate the at least one film or the stacked films.
- the recesses lead to a reduction in opacity. If the recesses have different depths, different opacities can be achieved in the region of the differently deep recesses.
- a method and a device for producing a security document and a security document are known.
- a substrate of a security document holes are introduced on the surface and applied in this an ink.
- This is preferably designed such that it comprises colorants which diffuse into the substrate.
- the ink applied by printing is introduced deeper into the document than an ink printed only on the surface and is thus better protected against adulteration and / or damage during use.
- these nowadays comprise in the majority of cases a lamination body produced from a plurality of plastic layers.
- a lamination body In such a lamination body, a plurality of different security features or security elements can be integrated. It is customary, for example, to partially or completely print the individual plastic layers prior to assembly by means of a lamination process and to store the individualization information in the security document via this.
- the patent document DE 10 2010 035 890 A1 discloses a method of making an individualized security document, comprising: providing a plurality of substrate layers; Gathering the substrate layers into a substrate layer stack and laminating the substrate layers gathered in the substrate layer stack to a lamination body.
- the individualization information is usually printed on an outer surface of a security document blank.
- the printing is usually done by thermal transfer printing or inkjet printing and can be done in color. It is also known to use UV-curing printing preparations for this purpose.
- the printed information is covered by another film or a lacquer layer. Such a further film is laminated, for example, to the document blank.
- the temperatures and pressures that would be necessary to bond such a film to the remaining security document blank to a monolithic body can not be achieved.
- a disadvantage of the known methods is that the protective layers can often be removed without destruction, so that subsequently the printed individualization information can be falsified or even completely removed and replaced. Subsequently, in many cases, the protective layer can either be replaced by an identical new protective layer or the previously removed protective layer can be applied again. Decentralized individualized security documents thus generally have a much lower level of security, especially with regard to subsequent falsification.
- the invention is therefore based on the object to provide an improved method for producing an individualized security document, in which preferably colored, particularly preferably full-color customization information can be stored in the security document, which improved protection against adulteration compared to printed on the surface Has security documents. Furthermore, the object of the invention is to provide a method for producing a security document blank with which such individualization is possible.
- the invention is based on the idea of providing or producing security document blanks in such a way that they comprise a lamination body in which a large number of security features are already integrated.
- the lamination body is formed and provided such that it has a plurality of recesses in an outer surface on an outer surface at least in a marking region.
- the individualization information is now applied to the outer surface in such a way that at least part of the individualization information penetrates into the recesses.
- a manipulation of the thus applied customization information is hardly possible, since in this case also at least the outer material layer, are embossed in the wells, damaged.
- the individualization information in the wells can not usually be completely overprinted by components of a forged and thus "new" customization information.
- a security feature is a feature that makes it difficult or impossible to falsify, imitate, or unauthorize an item.
- a security element is an entity that has at least one security feature. For the purpose of this definition, every security document also constitutes a security element.
- a monolithic lamination body is considered to be a body produced from a plurality of different layers, in which the individual substrate layers are joined together in such a way that, due to the chemical structure, the layer boundaries existing in front of the lamination can no longer be detected as phase transitions in the finished lamination body. It is obvious to a person skilled in the art that the originally present different substrate layers in the finished lamination body can be determined, for example, on the basis of the different admixtures of additives which contained the substrate layers used for producing the lamination body prior to lamination.
- a lamination body that composed of a plastic layer colored in color by means of color pigments in the volume and a transparent color-neutral plastic layer to form a monolithic lamination body, has in the finished lamination body different material layers which show different properties with respect to an interaction with light. With regard to the chemical polymer structure, however, a phase transition in a monolithic lamination body can not be detected.
- any information is individually associated with a security document to be produced. This means that this information differs for differently manufactured security documents.
- Personalization information is defined as such individualization information that is assigned to a person to whom the security document produced or to be produced is or will be assigned.
- a printing device As a digital printing device, a printing device is considered, which is provided for printing information in such a way that different information can be printed on successively manufactured plungers, without thereby a throughput of the printing device is significantly reduced or even setup times would be necessary.
- Inkjet printers or plotters are digital printing devices.
- the print image can be determined by a digital file.
- other digital printing devices print by a transfer printing process.
- As an information layer a plane inside a document body which has emerged from a printed surface of a substrate layer is referred to.
- the recesses are formed with opening dimensions on the outer surface in the range of 100 microns to 400 microns, preferably in the range of 150 microns to 300 microns and most preferably in the range of 200 microns +/- 10 microns.
- the diameters of the individual pits correspond approximately to the size of individual image pixels or a small number of image pixels when printing the customization information with a print resolution of about 600 dpi.
- a small number here is a natural number less than 10, preferably less than 5.
- the diameters of the depressions on the outer surface are thus selected so that they are of the order of a diameter of a pixel.
- a depth of the recesses is preferably in the range between 30 .mu.m and 200 .mu.m, more preferably between 50 .mu.m and 150 .mu.m.
- Lamination bodies have proven to be particularly suitable in which the multiplicity of depressions of a marking area are respectively introduced in a regular grid. This creates the possibility of storing almost any information in the security document to be produced solely by the proportion of the individualization information that is printed in the recesses. Similarly, almost any customization information may be printed such that one portion is stored on the outer surface and another portion is stored in the recesses. The prerequisite, however, is that the depressions form a grid in which the spacings of the depressions are small compared to the extent of the printed information structures.
- a grid is formed so that the centers of the recess on the outer surface have a distance from each other in the range of 1.2 times to 10 times the diameter of the recess on the outer surface, preferably in the region of the 1.3 times to 1.4 times the diameter, and most preferably 1.4 times the diameter.
- the recesses of a marking area all have the same geometric shape. This facilitates targeted printing in individual recesses when marking the security document blank. Furthermore, added and simulated pits can be more easily recognized because it is extremely difficult to accurately replicate pits of the same outer shape. This applies Especially when the individual wells also have the same dimensions in terms of their geometric shape in a plane of the outer surface.
- the recesses occupy about 40% of the outer surface in the region of the regular grid.
- Such an area ratio of the openings can be realized without impairing stability of the lamination body in the marking area.
- An area ratio of about 40% of the outer surface, the wells can accept even with an irregular arrangement of the wells.
- embodiments are also possible in which the recesses make up an area fraction of the outer surface which is in the range of 5% to 30%. As a result, stability and rigidity of the produced security document can be adjusted.
- the area fraction of the depressions, d. H. the openings, in the outer surface may be in a row in the range of 5% to 30%.
- the recesses are equidistant from one another in a row. If the rows, which have the same depression spacings and similar depressions, are oriented parallel to one another and have the same spacings to one another, this results in regular patterns.
- the area ratio of the recesses in the outer surface is preferably between 5% and 40%.
- a geometric shape of the recesses which has a polygonal cross-section in a plane of the surface of the security document blank or in a plane parallel to this surface.
- triangles, squares, rectangles, trapezoids, equilateral polygons, etc. are considered as angular cross-sectional shapes and shapes.
- Recesses with an angular cross-section are particularly difficult to replicate, so that such an angular cross-sectional shape or cross-sectional shape provides increased security against counterfeiting and counterfeiting.
- the area percentages of the apertures in the marking area may be 40%, but the cavities of the alternative embodiment have different geometrical shapes. Again, different angular cross-sectional shapes are preferred. However, it is also possible to use round, for example circular, oval cross-sectional shapes and forms. Also, a combination of angular and circular cross-sectional shapes and shapes is provided in some alternative embodiments.
- the depressions are imprinted by means of a laminating sheet during the lamination to the lamination body in a substrate layer forming the outer surface of the lamination body.
- the depressions can be embossed and formed in an already executed step.
- a lamination sheet is prepared or manufactured that contacts a contact surface which, when laminated, is brought into contact with a substrate layer forming the outer surface of the lamination body , a plurality of mutually separate structuring regions each having a plurality of bulges, wherein the contact surface is formed in each case circumferentially around each structuring region on the outside, and several marking areas are embossed during lamination by means of the plurality of structuring regions.
- the formation of the plurality of depressions may be effected by ultrasound being coupled into a sonotrode while it is in contact with at least a portion of the outer surface of the lamination body, thereby embossing the depressions.
- the sonotrode has a contact surface with a plurality of structuring regions formed separately from each other, each having a plurality of bulges and the contact surface in each case circumferentially around each Structuring region is formed just and by means of the sonotrode during the coupling of ultrasound into the outer surface of the lamination body a plurality of marking areas each having a plurality of depressions are impressed.
- a multiple benefit is divided into individual security document blanks prior to individualization. If individualization is carried out centrally, individualization can take place before separation.
- One embodiment thus provides for the lamination body to be divided into a plurality of security document blanks, each of which has at least one of the plurality of marking areas.
- the recesses of the marking area are impressed with different depths with respect to a flat smooth area of the outer surface, which surrounds the marking area with the plurality of recesses circumferentially.
- the proportion of information printed or to be printed in the recesses is thus introduced and stored at different levels or depths of the document relative to the outer surface of the security document blank. In the case of counterfeiting, this makes it particularly difficult to remove the old information that has to be manipulated.
- a depth of the recesses with respect to a flat smooth area of the outer surface, which circumferentially surrounds the marking area with the plurality of recesses is between 30 ⁇ m and 200 ⁇ m, more preferably between 50 ⁇ m and 150 ⁇ m.
- the marking area in the outer surface, wherein the projections against a level of the outer surface of the lamination body outside the marking area, which is formed flat and smooth and surrounding the marking area circumferentially, projecting.
- the marking area also includes the plurality of depressions that are recessed from the level of the outer surface of the lamination body outside the marking area, that is, project into the lamination body.
- protrusions can not be formed to a temperature close to the glass transition temperature of the plastic material of the outer material layer or even to a temperature above the glass transition temperature.
- cold-stamping methods and laser ablation methods for forming the pits have been eliminated since projections can not be realized with these methods.
- the portion of the individualizing information is printed pixel by pixel into the depressions by means of a preparation.
- the entire customization information can be printed pixel-precise in the wells.
- the outer material layer is preferably transparent and neutral in color.
- the individualization information may be applied over the entire area to the marking region, so that part of the individualization information is printed on the outer surface and a part of the individualization information is printed in the depressions.
- the individual information components for example components of a facial image, are then stored correlated to one another in different levels of the finished security document. This can be used for verification purposes of the security document. Even if the information portion applied to the outer surface, which is more easily accessible to manipulation, is distorted, it can be detected by the correlation between the proportion deposited on the outer surface and the proportion of the individualization information printed in the recesses , no longer completely exists.
- the individualization information can also be applied in part to the marking area in the manner that part of the individualization information is printed on the outer surface and a part of the individualization information is printed in the wells, but a part of the outer surface remains unprinted. In some embodiments, an information layer remains unprinted in the region of some depressions.
- the individualization information is printed by means of an inkjet printing process by means of one or more preparations.
- Inkjet printing devices are capable of selectively printing individual pixels in a preselected color by means of a formulation. This makes it possible, for example, to print the preparation in the individual wells with pixel accuracy.
- three preparations which each produce the color impression of a primary color in the printed state, full color individualization information, a color subtraction all color impressions in a spanned by the primary colors gamut for displaying the customization information can be used.
- inkjet printing devices are particularly preferred for printing, in which, in addition to the color preparations, which convey a color impression of a primary color, further preparations are used which, for example, produce a black color impression or additionally can cause further color impressions not lying in the gamut.
- the individualization information is combined with a security print which is applied to an information layer during the production of the lamination body.
- the document body is thus particularly preferably provided with a security print on an information layer, and the depressions are formed such that they have a depth which corresponds to the material layer thickness of the outer material layer.
- the proportion of the individualization information printed on the information layer through the pits is thus linked to the security print on the information layer. If a counterfeiter succeeds in removing portions of the individualization information printed on the information layer, this likewise leads to a change and / or damage to the security printing.
- preparations can be used which are translucent or transparent in the printed state, so that parts of the security print can still be perceived despite the overprinting by the individualization information.
- the individualization information is printed by means of at least one preparation which comprises a solvent which attacks the material of the outer material layer and / or the information layer so that the colorants of the preparation diffuse into the walls of the depressions in the outer material layer and / or or the information layer is favored.
- An inseparable connection between the printed individualization information and the respective material layer receiving the information can also be achieved by or in addition to the fact that the preparation is produced on the basis of the same plastic material from which the respective material layer or layers are made.
- preparations based on polycarbonate are suitable. Such preparations are for example in the DE 10 2007 052 947 A1 described.
- the DE 10 2007 052 947 A1 teaches the use of a preparation containing: A) 0.1 to 20% by weight of a binder with a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenylcycloalkane, B) 30 to 99.9% by weight of a preferably organic solvent or solvent mixture, C) 0 to 10% by weight, based on dry matter, of a colorant or colorant mixture, D) 0 to 10% by weight of a functional material or a mixture of functional materials, E) 0 to 30% by weight of additives and / or auxiliaries, or a mixture of such substances, the sum of components A) to E) always being 100% by weight, as an ink-jet printing ink.
- the wells are formed to conically extend from the outer surface of the lamination body to the information layer.
- the individualization information is printed in full color.
- the individualization information comprises a facial image of a user to whom the security document is or will be assigned.
- a cover layer or substrate layer is applied to the outer surface after printing the customization information printed at least partially in the recesses on the information layer inside the lamination body applied.
- This can be applied, for example, as a lacquer layer and be formed.
- a transparent color-neutral lacquer is used for this purpose.
- the recessed outer material layer additionally favors the bonding of the outer protective layer to the laminate body. Paint or glue can penetrate into the openings. This increases the connection area. The penetration of paint or adhesive in the wells prevents the subsequent overprinting of the customization information in the wells.
- a different geometry is also provided for the indentations.
- These recesses may have a cylindrical shape.
- the depressions may be circular, oval, triangular, square, polygonal, eg star-shaped, hexagonal, etc. be formed.
- the various cross-sectional shapes and geometries can be combined as desired. In a lamination body pits of different shapes can be combined.
- the individualized security documents produced in this way can be, on the one hand, security documents which are designed as plastic cards. Likewise, however, security documents can be personalized in this way, which are designed for example as passport book, in which a lamination body is integrated as a page.
- a stack 1 of substrate layers 2 is shown. These are assembled into a lamination body in a high pressure high temperature lamination process.
- the substrate layers 2 are preferably all made of the same plastic material, for example a polycarbonate material.
- the substrate layers may be made of another plastic material such as PVC, ABS, TPU, PET or the like.
- the substrate layers 2 are all made of the same plastic material.
- other embodiments may provide that the individual substrate layers 2 are also made of different plastic materials.
- the individual substrate layers 2 may have different colors and admixtures of additives.
- the surfaces can be individually printed. Furthermore, it is possible to insert further security elements (not shown) between the substrate layers and / or to emboss security features.
- An outer substrate layer 3 is preferably transparent and color-neutral at least in a region 7 provided for a later individualization.
- a so-called information substrate layer 5 Adjacent to the outer substrate layer 3, in the embodiment shown, a so-called information substrate layer 5 is arranged in the stack 1. This has a safety pressure 6 on an upper side 8.
- a security print 6 includes, for example, a guilloche pattern or the like. The security print 6 can be executed in full color.

- FIG. 2a Such is schematically in Fig. 2a shown.
- microstructuring having a plurality of depressions 14 is embossed into an outer surface 19 of the lamination body 11 to be formed.
- a contact surface 61 of the laminating sheet 60 which is in Fig. 1 is shown, has a plurality of bulges 63 in a structuring region 62 for this purpose. Surrounding the structuring area, the contact surface is smooth and flat. In the lamination body 11, this creates a smooth, flat area around the marking area 7.
- the recesses 14 in this case open to an outer surface 19 of a document body 11. In the illustrated embodiment, these penetrate an outer material layer 13 whose layer thickness 21 of the substrate layer thickness 27 of the outer substrate layer 3 (cf. Fig. 1 ) corresponds approximately.
- the recesses 14 completely penetrate the outer material layer 13, which has emerged from the outer substrate layer 3, as far as an information layer 15 on which the security printing 16 is formed.
- the security pressure is thereby preferably not changed or damaged.
- the information layer 15 has been formed from the information substrate layer 5.
- the security pressure 16 is shown as a dashed line. It is noted at this point that the individual substrate layers 2 (see FIG. Fig.
- the lamination body is not monolithic.
- the lamination body may be made of substrate layers made on the basis of different plastic materials.
- the depressions 14 preferably have a diameter 22 in the order of magnitude of 100 ⁇ m to 400 ⁇ m, particularly preferably in the range of 150 ⁇ m to 300 ⁇ m.

- an individualization information 18 is printed on an outer surface 19 of the lamination body 11. This is preferably done by means of a digital printing method, in particular an inkjet printing method. Individual pixels are printed on the outer surface 19 of the lamination body 11 with different formulations. A portion of the individualization information 18-1 is hereby printed on the information layer 15 through the depressions 14. This means that the preparation used penetrates into the depressions 14 and, for example, is guided to the information layer 15 by means of a capillary effect. There, a part 18-1 of the individualization information 18 thus connects to the security print 16. A further part 18-2 of the individualization information remains on the outer surface 19 virtually on the webs between the depressions 14. The individualization information 18 thus becomes in two different levels of the lamination body 11 stored.
- the one part 18-1 of the individualization information is printed in the recesses 14 with pixel precision. In one embodiment, it may be provided that only the one part 18-1, which is printed with pixel precision in the depressions 14, is used as individualization information 18. In this case, there are thus no information components which remain on the outer surface 19, ie the webs between the recesses 14.
- the preparations used may preferably be designed so that the resulting color impression of the entire customization information 18 is full-color.
- the preparations thus preferably comprise at least three preparations which, in the printed state, each produce a color impression of a primary color of a color system in a human observer.
- the preparations are preferably designed such that the formed pixels, in particular in the region of the recesses 14 are translucent, so that a part of the security print 16 also in the region of the recesses 14 remains recognizable by the part of the individualization information 18-1, which depends on the Information layer 15 is printed. As a result, an optimal connection of the individualization information 18 with the security pressure 16 is achieved.

- a lacquer layer 40 is applied to the outer surface 19, which are applied in this way can that the recesses 14 are filled with the paint. This results in a smooth surface of the finished document body 80.
- the document body 80 itself is the security document 90. In other embodiments, the document body 80 may be sewn into a passport that represents the finished security document.
- FIG. 2 is a schematic plan view of a security document 90 formed as a card. It can be seen that in a marking region 17, a facial image is formed, which is preferably formed in full color. Schematically indicated is a grid of recesses 14. A portion of the individualization information 18 in the form of the facial image is thus printed by the recesses 14 on an information layer on which a security print 16 is applied. The pits do not have to exist over the entire area to which customization information is applied. However, the depressions preferably extend over the entire area to which individualization information is printed in order to adequately protect all individualization information about the storage of an information component in the interior of the lamination body 11.
- FIG. 4a schematically a utility layout for a lamination body 11 is shown, which is designed as a 20-fold benefit for individual card-shaped security document blanks.

Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines individualisierten Sicherheitsdokuments sowie ein Verfahren zum Herstellen eines individualisierbaren Sicherheitsdokumentenrohlings. Insbesondere betrifft die Erfindung ein Verfahren zum Herstellen eines individualisierten Sicherheitsdokuments, wobei eine farbige, besonders bevorzugt vollfarbige Individualisierungsinformation in ein Sicherheitsdokument eingebracht wird, und einen Verfahren zum Herstellen eines Sicherheitsdokumentenrohlings, der farbig individualisierbar ist.The invention relates to a method for producing an individualized security document and to a method for producing an individualizable security document blank. In particular, the invention relates to a method for producing an individualized security document, wherein a colored, particularly preferably full-color customization information is introduced into a security document, and a method for producing a security document blank, which is color customizable.
Aus dem Stand der Technik ist es bekannt, Sicherheitsdokumente mit Informationen zu versehen, welche individuell dem jeweiligen Sicherheitsdokument zugeordnet sind. Eine solche individuelle Information, welche auch als Individualisierungsinformation bezeichnet wird, ist beispielsweise eine Seriennummer eines Dokuments. Bei einer Vielzahl von Sicherheitsdokumenten ist es darüber hinaus üblich, Informationen einer Person in dem Sicherheitsdokument als Individualisierungsinformationen zu speichern, der das Sicherheitsdokument zugeordnet ist. Bei einem Passdokument umfassen die Individualisierungsinformationen beispielsweise einen Namen, einen Vornamen, ein Geburtsdatum, einen Wohnort, Angaben über biometrische Merkmale wie eine Körpergröße, eine Augenfarbe oder auch ein Fingerabdruckmuster oder ein Gesichtsbild, um einige Personalisierungsmerkmale aufzuführen.From the prior art it is known to provide security documents with information which are individually associated with the respective security document. Such individual information, which is also referred to as customization information, is, for example, a serial number of a document. Moreover, in a variety of security documents, it is common to store information of a person in the security document as customization information associated with the security document. For example, in a passport document, the personalization information includes a name, a first name, a date of birth, a place of residence, information on biometric features such as a height, an eye color, or a fingerprint pattern or a face image to list some personalization features.
Als Sicherheitsdokumente werden Dokumente angesehen, die mindestens ein Merkmal aufweisen, welches ein Nachahmen, Duplizieren und/oder Verfälschen oder Ähnliches deutlich erschwert oder unmöglich macht. Sicherheitsdokumente umfassen beispielsweise Reisepässe, Personalausweise, Identitätskarten, Zugangskarten, Führerscheine, Visa, Kreditkarten, Postwertzeichen, Wertpapiere, aber auch mit Sicherheitsmerkmalen versehene Eintrittskarten, Echtheitssiegel oder gegen Fälschungen geschützte Verpackungen, um einige beispielhaft aufzuzählen. Gemeinsam ist allen, dass diese mindestens ein, in der Regel mehrere Sicherheitsmerkmale oder Sicherheitselemente umfassen, die eine Verfälschung, Nachahmung, Duplizierung und/oder unautorisierte Herstellung erschweren oder unmöglich machen.Security documents are considered to be documents which have at least one feature which makes copying, duplicating and / or falsifying or the like considerably more difficult or impossible. Security documents include, for example, passports, identity cards, identity cards, access cards, driver's licenses, visas, credit cards, postage stamps, securities, but also security-enhanced tickets, seals of authenticity or counterfeit-protected packaging, to enumerate some by way of example. Common to all is that they include at least one, usually several security features or security elements that make it difficult or impossible falsification, imitation, duplication and / or unauthorized production.

Um besonders fälschungssichere Sicherheitsdokumente zu erhalten, umfassen diese heutzutage in der Mehrzahl einen aus mehreren Kunststoffschichten hergestellten Laminationskörper. In einen solchen Laminationskörper kann eine Vielzahl unterschiedlicher Sicherheitsmerkmale oder Sicherheitselemente integriert werden. Üblich ist es beispielsweise die einzelnen Kunststoffschichten vor dem Zusammenfügen mittels eines Laminationsverfahrens teil- oder vollflächig zu bedrucken und hierüber die Individualisierungsinformation in das Sicherheitsdokument zu speichern.In order to obtain particularly tamper-proof security documents, these nowadays comprise in the majority of cases a lamination body produced from a plurality of plastic layers. In such a lamination body, a plurality of different security features or security elements can be integrated. It is customary, for example, to partially or completely print the individual plastic layers prior to assembly by means of a lamination process and to store the individualization information in the security document via this.
Das Patentdokument
Insbesondere bei Ausführungsformen, bei denen die einzelnen zusammengefügten Kunststoffschichten aus demselben thermoplastischen Kunststoffmaterial hergestellt sind, lassen sich auf diese Weise nahezu monolithische Laminationskörper schaffen, die eine Manipulation der gespeicherten Individualisierungsinformationen stark erschweren. Eine Voraussetzung hierfür ist jedoch, dass die Individualisierungsinformationen auf eine innere oder in eine innere Schicht gespeichert werden und anschließend eine sehr gute Verbindung zwischen den einzelnen Kunststoffschichten ausgebildet wird. Dies ist in der Regel nur in großen Produktionsanlagen möglich, so dass eine Herstellung solcher Sicherheitsdokumente zentralisiert in einer oder wenigen Fertigungsstätten zu erfolgen hat.In particular, in embodiments in which the individual assembled plastic layers are made of the same thermoplastic material, can be created in this way almost monolithic lamination body, the one Making manipulation of stored personalization information difficult. A prerequisite for this, however, is that the individualization information is stored on an inner or inner layer and then a very good connection between the individual plastic layers is formed. As a rule, this is only possible in large production plants, so that production of such security documents has to be carried out centrally in one or a few production plants.
Aus dem Stand der Technik sind jedoch auch Vorrichtungen bekannt, mit denen ein Einspeichern von Individualisierungsinformationen dezentral erfolgen kann. Hierbei werden die Individualisierungsinformationen in der Regel auf eine äußere Oberfläche eines Sicherheitsdokumentenrohlings aufgedruckt. Das Aufdrucken erfolgt in der Regel mittels Thermotransferdruck oder Inkjetdruck und kann farbig vorgenommen werden. Ebenso ist es bekannt, hierfür UV-härtende Druckzubereitungen zu verwenden. Um eine Manipulation der aufgedruckten Individualisierungsinformation zu erschweren, wird die aufgedruckte Information durch eine weitere Folie oder eine Lackschicht abgedeckt. Eine solche weitere Folie wird beispielsweise auf den Dokumentrohling auflaminiert. In einer dezentralen Einrichtung lassen sich jedoch nicht die Temperaturen und Drücke erreichen, die notwendig wären, um eine solche Folie mit dem restlichen Sicherheitsdokumentenrohling zu einem monolithischen Körper zu verbinden. Zusätzlich ist es bekannt, teil- oder ganzflächig Hologramme über die Individualisierungsinformationen anzubringen.However, devices are known from the prior art, with which a storage of customization information can be done locally. In this case, the individualization information is usually printed on an outer surface of a security document blank. The printing is usually done by thermal transfer printing or inkjet printing and can be done in color. It is also known to use UV-curing printing preparations for this purpose. To complicate a manipulation of the printed customization information, the printed information is covered by another film or a lacquer layer. Such a further film is laminated, for example, to the document blank. However, in a remote facility, the temperatures and pressures that would be necessary to bond such a film to the remaining security document blank to a monolithic body can not be achieved. In addition, it is known to install partial or full area holograms on the customization information.
Nachteilig an den bekannten Verfahren ist es jedoch, dass die Schutzschichten sich häufig zerstörungsfrei entfernen lassen, so dass anschließend die aufgedruckte Individualisierungsinformation verfälscht oder sogar vollständig entfernt und ersetzt werden kann. Anschließend kann in vielen Fällen die Schutzschicht entweder durch eine identische neue Schutzschicht ersetzt oder die zuvor abgenommene Schutzschicht erneut appliziert werden. Dezentral individualisierte Sicherheitsdokumente weisen somit in der Regel eine sehr viel geringere Sicherheit insbesondere gegenüber nachträglichen Verfälschungen auf.A disadvantage of the known methods, however, is that the protective layers can often be removed without destruction, so that subsequently the printed individualization information can be falsified or even completely removed and replaced. Subsequently, in many cases, the protective layer can either be replaced by an identical new protective layer or the previously removed protective layer can be applied again. Decentralized individualized security documents thus generally have a much lower level of security, especially with regard to subsequent falsification.
Der Erfindung liegt somit die Aufgabe zugrunde, ein verbessertes Verfahren zum Herstellen eines individualisierten Sicherheitsdokuments zu schaffen, bei dem vorzugsweise farbige, besonders bevorzugt vollfarbige Individualisierungsinformationen in das Sicherheitsdokument eingespeichert werden können, welches einen verbesserten Schutz gegen Verfälschungen im Vergleich zu an der Oberfläche bedruckten Sicherheitsdokumenten aufweist. Ferner liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Herstellen eines Sicherheitsdokumentenrohlings anzugeben, mit dem eine solche Individualisierung möglich ist.The invention is therefore based on the object to provide an improved method for producing an individualized security document, in which preferably colored, particularly preferably full-color customization information can be stored in the security document, which improved protection against adulteration compared to printed on the surface Has security documents. Furthermore, the object of the invention is to provide a method for producing a security document blank with which such individualization is possible.
Der Erfindung liegt die Idee zugrunde, Sicherheitsdokumentrohlinge in der Weise bereitzustellen oder herzustellen, dass diese einen Laminationskörper umfassen, in den bereits eine Vielzahl von Sicherheitsmerkmalen integriert ist. Der Laminationskörper wird so ausgebildet und bereitgestellt, dass dieser an einer Außenfläche zumindest in einem Markierungsbereich eine Vielzahl von Vertiefungen in einer Außenfläche aufweist. Die Individualisierungsinformation wird nun auf die Außenfläche in der Weise aufgebracht, dass zumindest ein Teil der Individualisierungsinformation in die Vertiefungen eindringt. Eine Manipulation der so aufgebrachten Individualisierungsinformation ist kaum möglich, da hierbei auch zumindest die äußere Materialschicht, in die Vertiefungen eingeprägt sind, beschädigt wird. Ferner können die Individualisierungsinformationen in den Vertiefungen in der Regel nicht vollständig durch Bestandteile einer gefälschten und somit "neuen" Individualisierungsinformation überdruckt werden.The invention is based on the idea of providing or producing security document blanks in such a way that they comprise a lamination body in which a large number of security features are already integrated. The lamination body is formed and provided such that it has a plurality of recesses in an outer surface on an outer surface at least in a marking region. The individualization information is now applied to the outer surface in such a way that at least part of the individualization information penetrates into the recesses. A manipulation of the thus applied customization information is hardly possible, since in this case also at least the outer material layer, are embossed in the wells, damaged. Furthermore, the individualization information in the wells can not usually be completely overprinted by components of a forged and thus "new" customization information.
Ein Sicherheitsmerkmal ist ein Merkmal, welches eine Verfälschung, Nachahmung oder unautorisierte Herstellung eines Gegenstands erschwert oder unmöglich macht.A security feature is a feature that makes it difficult or impossible to falsify, imitate, or unauthorize an item.
Ein Sicherheitselement ist eine Entität, die mindestens ein Sicherheitsmerkmal aufweist. Im Sinne dieser Definition stellt auch jedes Sicherheitsdokument ein Sicherheitselement dar.A security element is an entity that has at least one security feature. For the purpose of this definition, every security document also constitutes a security element.
Als monolithischer Laminationskörper wird ein aus mehreren unterschiedlichen Schichten hergestellter Körper angesehen, bei dem die einzelnen Substratschichten so miteinander verbunden werden, dass aufgrund der chemischen Struktur die vor der Lamination vorhandenen Schichtgrenzen in dem fertigen Laminationskörper nicht mehr als Phasenübergänge nachweisbar sind. Es versteht sich für den Fachmann, dass sich die ursprünglich vorhandenen unterschiedlichen Substratschichten im fertigen Laminationskörper beispielsweise anhand der unterschiedlichen Beimengungen von Zusatzstoffen ermitteln lassen, die die zur Erstellung des Laminationskörpers verwendeten Substratschichten vor der Lamination enthielten. Ein Laminationskörper, der aus einer mittels Farbpigmenten im Volumen durchgefärbten Kunststoffschicht und einer transparenten farbneutralen Kunststoffschicht zu einem monolithischen Laminationskörper zusammengefügt wird, weist im fertigen Laminationskörper unterschiedliche Materialschichten auf, die unterschiedliche Eigenschaften in Bezug auf eine Wechselwirkung mit Licht zeigen. Hinsichtlich der chemischen Polymerstruktur ist jedoch ein Phasenübergang bei einem monolithischen Laminationskörper nicht feststellbar.A monolithic lamination body is considered to be a body produced from a plurality of different layers, in which the individual substrate layers are joined together in such a way that, due to the chemical structure, the layer boundaries existing in front of the lamination can no longer be detected as phase transitions in the finished lamination body. It is obvious to a person skilled in the art that the originally present different substrate layers in the finished lamination body can be determined, for example, on the basis of the different admixtures of additives which contained the substrate layers used for producing the lamination body prior to lamination. A lamination body that composed of a plastic layer colored in color by means of color pigments in the volume and a transparent color-neutral plastic layer to form a monolithic lamination body, has in the finished lamination body different material layers which show different properties with respect to an interaction with light. With regard to the chemical polymer structure, however, a phase transition in a monolithic lamination body can not be detected.
Als farbig wird eine Substanz oder Zubereitung angesehen, die bei einem menschlichen Betrachter einen Farbeindruck hervorruft. Schwarz- und Graustufentöne werden in diesem Zusammenhang nicht als farbig angesehen. Als bunt wird ein Gegenstand angesehen, wenn dieser zwei unterschiedliche Farbeindrücke bei einem menschlichen Betrachter hervorruft. Als vollfarbig wird ein Gegenstand bezeichnet, der eine Vielzahl von Farbeindrücken aus einem aufgespannten Gamut umfasst, der von drei Primärfarben aufgespannt wird. Als vollfarbig werden beispielsweise Drucke angesehen, die mit einem Mehrfarbdrucksystem hergestellt sind, welches als primäre Farben beispielsweise die Farben Cyan, Gelb und Magenta umfasst. Voraussetzung ist selbstverständlich, dass die zu druckende Information selbst farbig ausgestaltet ist. Bei einem vollfarbig ausgebildeten Druck können auch Anteile mit einer schwarzen Farbe gedruckt sein. Es müssen aber auch farbige Anteile enthalten sein.As colored a substance or preparation is considered, which causes a color impression in a human observer. Black and gray tones are not considered colored in this context. An object is considered to be colored when it causes two different color impressions in a human observer. Full color is an article that contains a multitude of color impressions from a spanned gamut spanned by three primary colors. For example, prints that are made with a multicolor printing system comprising as primary colors, for example, the colors cyan, yellow and magenta are considered to be full-color. The prerequisite is, of course, that the information to be printed is itself colored. In the case of full-color printing, it is also possible for parts to be printed with a black color. But it must also be colored parts.
Als Individualisierungsinformation wird jede Information bezeichnet, die einem herzustellenden Sicherheitsdokument individuell zugeordnet ist. Dies bedeutet, dass sich diese Information für unterschiedlich hergestellte Sicherheitsdokumente unterscheidet. Als Personalisierungsinformation wird eine solche Individualisierungsinformation bezeichnet, die einer Person zugeordnet ist, der das hergestellte oder herzustellende Sicherheitsdokument zugeordnet ist oder wird.As customization information, any information is individually associated with a security document to be produced. This means that this information differs for differently manufactured security documents. Personalization information is defined as such individualization information that is assigned to a person to whom the security document produced or to be produced is or will be assigned.
Als digitale Druckeinrichtung wird eine Druckeinrichtung betrachtet, die für ein Drucken von Informationen in der Weise vorgesehen ist, dass auf nacheinander gefertigte Druckstücke jeweils unterschiedliche Informationen druckbar sind, ohne dass hierdurch ein Durchsatz der Druckeinrichtung deutlich verringert wird oder gar Einrüstzeiten von Nöten wären. Tintenstrahldrucker oder auch Plotter stellen digitale Druckeinrichtungen dar. Das Druckbild kann jeweils anhand einer digitalen Datei festgelegt werden. Weitere digitale Druckeinrichtungen drucken beispielsweise nach einem Transferdruckverfahren. Als eine Informationsschicht wird eine Ebene im Innern eines Dokumentkörpers bezeichnet, die aus einer bedruckten Oberfläche einer Substratschicht hervorgegangen ist.As a digital printing device, a printing device is considered, which is provided for printing information in such a way that different information can be printed on successively manufactured plungers, without thereby a throughput of the printing device is significantly reduced or even setup times would be necessary. Inkjet printers or plotters are digital printing devices. The print image can be determined by a digital file. For example, other digital printing devices print by a transfer printing process. As an information layer, a plane inside a document body which has emerged from a printed surface of a substrate layer is referred to.
Insbesondere wird ein Verfahren zum Herstellen eines individualisierten Sicherheitsdokuments vorgeschlagen, welches die Schritte umfasst:
- Bereitstellen von mehreren Substratschichten;
- Zusammentragen der Substratschichten zu einem Substratschichtenstapel;
- Laminieren der in dem Substratschichtenstapel zusammengetragenen Substratschichten zu einem Laminationskörper;
- Bereitstellen einer digitalen Druckeinrichtung;
- Bedrucken mindestens eines Markierungsbereichs einer Außenfläche des Laminationskörpers mittels der digitalen Druckeinrichtung zum Speichern von Individualisierungsinformationen;
- wobei
- in die eine Außenfläche des Laminationskörpers vor dem Bedrucken in dem mindestens einen Markierungsbereich eine Mikrostrukturierung mit einer Vielzahl von Vertiefungen eingeprägt wird und das Bedrucken so erfolgt, dass ein Teil der verdrucken Tinte in die Vertiefungen eindringt.
- Providing a plurality of substrate layers;
- Gathering the substrate layers into a substrate layer stack;
- Laminating the substrate layers gathered in the substrate layer stack to a lamination body;
- Providing a digital printing device;
- Printing at least one marking area of an outer surface of the lamination body by the digital printing means for storing customization information;
- in which
- into which an outer surface of the lamination body prior to printing in the at least one marking region is embossed with a microstructure having a plurality of depressions and the printing is carried out so that a part of the printed ink penetrates into the depressions.
Ferner wird ein Verfahren zum Herstellen eines Sicherheitsdokumentenrohlings, der an einer Außenfläche mindestens einen Markierungsbereich für ein Bedrucken aufweist, vorgeschlagen, welches die Schritte umfasst:
- Bereitstellen von mehreren Substratschichten;
- Zusammentragen der Substratschichten zu einem Substratschichtenstapel;
- Laminieren der in dem Substratschichtenstapel zusammengetragenen Substratschichten zu einem Laminationskörper;
- dadurch gekennzeichnet, dass
- in die eine Außenfläche des Laminationskörpers in dem mindestens einen Markierungsbereich eine Mikrostrukturierung mit einer Vielzahl von Vertiefungen eingeprägt wird.
- Providing a plurality of substrate layers;
- Gathering the substrate layers into a substrate layer stack;
- Laminating the substrate layers gathered in the substrate layer stack to a lamination body;
- characterized in that
- into which an outer surface of the lamination body in the at least one marking region is impressed microstructuring with a plurality of recesses.
Die Vertiefungen werden mit Öffnungsabmessungen an der Außenfläche im Bereich von 100 µm bis 400 µm, bevorzugt im Beriech von 150 µm bis 300 µm und am bevorzugtesten im Bereich von 200 µm +/- 10 µm ausgebildet. Bei einer solchen Wahl entsprechen die Durchmesser der einzelnen Vertiefungen in etwa der Größe einzelner Bildpixel oder einer geringen Anzahl von Bildpixeln, wenn das Drucken der Individualisierungsinformationen mit einer Druckauflösung von etwa 600 dpi vorgenommen wird. Eine geringe Anzahl ist hier eine natürliche Zahl kleiner 10, vorzugsweise kleiner 5. Bei einer bevorzugten Ausführungsform sind somit die Durchmesser der Vertiefungen an der Außenfläche so gewählt, dass diese in der Größenordnung eines Durchmessers eines Pixels liegen.The recesses are formed with opening dimensions on the outer surface in the range of 100 microns to 400 microns, preferably in the range of 150 microns to 300 microns and most preferably in the range of 200 microns +/- 10 microns. In such a choice, the diameters of the individual pits correspond approximately to the size of individual image pixels or a small number of image pixels when printing the customization information with a print resolution of about 600 dpi. A small number here is a natural number less than 10, preferably less than 5. In a preferred embodiment, the diameters of the depressions on the outer surface are thus selected so that they are of the order of a diameter of a pixel.
Eine Tiefe der Vertiefungen liegt vorzugsweise im Bereich zwischen 30 µm und 200 µm besonders bevorzugt zwischen 50 µm und 150 µm.A depth of the recesses is preferably in the range between 30 .mu.m and 200 .mu.m, more preferably between 50 .mu.m and 150 .mu.m.
Als besonders geeignet haben sich Laminationskörper erwiesen, bei denen die Vielzahl der Vertiefungen eines Markierungsbereichs jeweils in einem regelmäßigen Raster eingebracht wird. Hierdurch wird die Möglichkeit geschaffen, eine nahezu beliebige Information in dem herzustellenden Sicherheitsdokument allein durch den Anteil der Individualisierungsinformationen zu speichern, der in die Vertiefungen gedruckt wird. Ebenso kann nahezu jede beliebige Individualisierungsinformation so aufgedruckt werden, dass ein Anteil auf der Außenfläche gespeichert ist und ein anderer Anteil in den Vertiefungen. Voraussetzung ist jedoch, dass die Vertiefungen ein Raster bilden, in dem die Abstände der Vertiefungen klein gegen die Ausdehnung der gedruckten Informationsstrukturen sind.Lamination bodies have proven to be particularly suitable in which the multiplicity of depressions of a marking area are respectively introduced in a regular grid. This creates the possibility of storing almost any information in the security document to be produced solely by the proportion of the individualization information that is printed in the recesses. Similarly, almost any customization information may be printed such that one portion is stored on the outer surface and another portion is stored in the recesses. The prerequisite, however, is that the depressions form a grid in which the spacings of the depressions are small compared to the extent of the printed information structures.
Vorzugsweise ist ein Raster so ausgebildet, dass die Mittelpunkte der Vertiefung an der Außenfläche einen Abstand zueinander aufweisen, der im Bereich von dem 1,2-fachen bis zu dem 10-fachen des Durchmessers der Vertiefung an der Außenfläche, bevorzugt in dem Bereich von dem 1,3-fachen bis zum 1,4-fachen des Durchmessers liegt und am bevorzugtesten dem 1,4-fachen des Durchmessers entspricht.Preferably, a grid is formed so that the centers of the recess on the outer surface have a distance from each other in the range of 1.2 times to 10 times the diameter of the recess on the outer surface, preferably in the region of the 1.3 times to 1.4 times the diameter, and most preferably 1.4 times the diameter.
Ebenso wird es bevorzugt, dass die Vertiefungen eines Markierungsbereichs alle eine gleiche geometrische Gestalt aufweisen. Hierdurch wird ein gezieltes Drucken in einzelne Vertiefungen bei der Markierung des Sicherheitsdokumentenrohlings erleichtert. Ferner können zugefügte und nachgebildete Vertiefungen leichter erkannt werden, da es extrem schwer ist, Vertiefungen mit derselben äußeren Gestalt exakt nachzubilden. Dies gilt besonders dann, wenn die einzelnen Vertiefungen auch noch dieselben Abmessungen hinsichtlich Ihrer geometrischen Gestalt in einer Ebene der äußeren Oberfläche aufweisen.It is also preferred that the recesses of a marking area all have the same geometric shape. This facilitates targeted printing in individual recesses when marking the security document blank. Furthermore, added and simulated pits can be more easily recognized because it is extremely difficult to accurately replicate pits of the same outer shape. this applies Especially when the individual wells also have the same dimensions in terms of their geometric shape in a plane of the outer surface.
Bei einer solchen Ausführungsform nehmen die Vertiefungen etwa 40 % der Außenfläche in dem Bereich des regelmäßigen Rasters ein. Ein solcher Flächenanteil der Öffnungen lässt sich realisieren, ohne eine Stabilität des Laminationskörpers in dem Markierungsbereich zu beeinträchtigen.In such an embodiment, the recesses occupy about 40% of the outer surface in the region of the regular grid. Such an area ratio of the openings can be realized without impairing stability of the lamination body in the marking area.
Einen Flächenanteil von etwa 40 % der Außenfläche können die Vertiefungen auch bei einer unregelmäßigen Anordnung der Vertiefungen annehmen.An area ratio of about 40% of the outer surface, the wells can accept even with an irregular arrangement of the wells.
Des Weiteren sind ebenfalls Ausführungsformen möglich, bei denen die Vertiefungen einen Flächenanteil der Außenfläche ausmachen, der im Bereich von 5 % bis 30 % beträgt. Hierdurch kann eine Stabilität und Steifigkeit des hergestellten Sicherheitsdokuments eingestellt werden.Furthermore, embodiments are also possible in which the recesses make up an area fraction of the outer surface which is in the range of 5% to 30%. As a result, stability and rigidity of the produced security document can be adjusted.
Ebenso ist es möglich die Vertiefungen in Reihen anzuordnen. Der Flächenanteil der Vertiefungen, d. h. der Öffnungen, in der Außenfläche kann hierbei in einer Reihe im Bereich von 5 % bis 30 % betragen.It is also possible to arrange the depressions in rows. The area fraction of the depressions, d. H. the openings, in the outer surface may be in a row in the range of 5% to 30%.
Vorzugsweise sind die Vertiefungen in einer Reihe zueinander gleich beabstandet. Sind die Reihen, die dieselben Vertiefungsabstände und gleichartige Vertiefungen aufweisen, parallel zueinander orientiert und weisen diese zueinander gleiche Abstände auf, so ergeben sich regelmäßige Raster. Der Flächenanteil der Vertiefungen in der Außenfläche beträgt vorzugsweise zwischen 5 % und 40 %.Preferably, the recesses are equidistant from one another in a row. If the rows, which have the same depression spacings and similar depressions, are oriented parallel to one another and have the same spacings to one another, this results in regular patterns. The area ratio of the recesses in the outer surface is preferably between 5% and 40%.
Besonders bevorzugt wird eine geometrische Gestalt der Vertiefungen, welche einen eckigen Querschnitt in einer Ebene der Oberfläche des Sicherheitsdokumentenrohlings oder in einer Ebene parallel zu dieser Oberfläche aufweist. Als eckige Querschnittsformen und- gestalten kommen insbesondere Dreiecke, Quadrate, Rechtecke, Trapeze, gleichseitige Vielecke usw. in Betracht. Vertiefungen mit einem eckigen Querschnitt sind besonders schwer nachzubilden, so dass eine solche eckige Querschnittsform oder Querschnittsgestalt eine erhöhte Sicherheit gegen Fälschungen und Nachahmungen bietet.Particularly preferred is a geometric shape of the recesses, which has a polygonal cross-section in a plane of the surface of the security document blank or in a plane parallel to this surface. In particular, triangles, squares, rectangles, trapezoids, equilateral polygons, etc. are considered as angular cross-sectional shapes and shapes. Recesses with an angular cross-section are particularly difficult to replicate, so that such an angular cross-sectional shape or cross-sectional shape provides increased security against counterfeiting and counterfeiting.
Auch bei einer alternativen Ausführungsform können die Flächenanteile der Öffnungen im Markierungsbereich 40% betragen, die Vertiefungen der alternativen Ausführungsform weisen jedoch unterschiedliche geometrische Gestalten auf. Erneut werden unterschiedliche eckige Querschnittsformen bevorzugt. Es können jedoch auch runde, beispielsweise kreisförmige, ovale Querschnittsgestalten und -formen verwendet werden. Auch eine Kombination von eckigen und runden Querschnittsgestalten und -formen ist bei einigen alternativen Ausführungsformen vorgesehen.Also in an alternative embodiment, the area percentages of the apertures in the marking area may be 40%, but the cavities of the alternative embodiment have different geometrical shapes. Again, different angular cross-sectional shapes are preferred. However, it is also possible to use round, for example circular, oval cross-sectional shapes and forms. Also, a combination of angular and circular cross-sectional shapes and shapes is provided in some alternative embodiments.
Bei einer Ausführungsform ist vorgesehen, dass die Vertiefungen mittels eines Laminationsblechs während des Laminierens zu dem Laminationskörper in eine die Außenfläche des Laminationskörpers bildende Substratschicht eingeprägt werden. Hierdurch können die Vertiefungen in einem ohnehin ausgeführten Arbeitsschritt eingeprägt und ausgebildet werden.In one embodiment, it is provided that the depressions are imprinted by means of a laminating sheet during the lamination to the lamination body in a substrate layer forming the outer surface of the lamination body. As a result, the depressions can be embossed and formed in an already executed step.
Wenn die Herstellung in einem Mehrfachnutzen erfolgt oder mehrere getrennte Markierungsbereiche ausgebildet werden sollen, ist bei einer Ausführungsform vorgesehen, dass ein Laminationsblech bereit- oder hergestellt wird, das an einer Kontaktfläche, welche beim Laminieren mit einer die Außenfläche des Laminationskörpers bildenden Substratschicht in Kontakt gebracht wird, mehrere voneinander getrennte Strukturierungsgebiete mit jeweils einer Vielzahl von Auswölbungen aufweist, wobei die Kontaktfläche jeweils außen umlaufend um jedes Strukturierungsgebiet eben ausgebildet ist, und beim Laminieren mittels der mehreren Strukturierungsgebiete mehre Markierungsbereiche eingeprägt werden.In one embodiment, when the manufacturing is in a multiple use or multiple distinct marking areas are to be formed, it is provided that a lamination sheet is prepared or manufactured that contacts a contact surface which, when laminated, is brought into contact with a substrate layer forming the outer surface of the lamination body , a plurality of mutually separate structuring regions each having a plurality of bulges, wherein the contact surface is formed in each case circumferentially around each structuring region on the outside, and several marking areas are embossed during lamination by means of the plurality of structuring regions.
Alternativ kann das Ausbilden der Vielzahl von Vertiefungen erfolgen, indem in eine Sonotrode, während diese zumindest mit einem Teilbereich der Außenfläche des Laminationskörpers in Kontakt ist, Ultraschall eingekoppelt wird und hierdurch die Vertiefungen eingeprägt werden.Alternatively, the formation of the plurality of depressions may be effected by ultrasound being coupled into a sonotrode while it is in contact with at least a portion of the outer surface of the lamination body, thereby embossing the depressions.
Um erneut einen Mehrfachnutzen herzustellen oder mehrere Markierungsbereiche in einem Sicherheitsdokument oder Sicherheitsdokumentenrohling vorzusehen, ist bei einer Ausführungsform vorgesehen, dass die Sonotrode eine Kontaktfläche mit mehreren voneinander getrennt ausgebildeten Strukturierungsgebieten mit jeweils einer Vielzahl von Auswölbungen aufweist und die Kontaktfläche jeweils außen umlaufend um jedes Strukturierungsgebiet eben ausgebildet ist und mittels der Sonotrode während der Einkopplung von Ultraschall in die Außenfläche des Laminationskörpers mehrere Markierungsbereiche mit jeweils einer Vielzahl von Vertiefungen eingeprägt werden.In order to produce a multiple benefit again or to provide several marking areas in a security document or security document blank, in one embodiment it is provided that the sonotrode has a contact surface with a plurality of structuring regions formed separately from each other, each having a plurality of bulges and the contact surface in each case circumferentially around each Structuring region is formed just and by means of the sonotrode during the coupling of ultrasound into the outer surface of the lamination body a plurality of marking areas each having a plurality of depressions are impressed.
Bevorzugt wird ein Mehrfachnutzen vor dem Individualisieren in einzelne Sicherheitsdokumentenrohlinge zerteilt. Wird die Individualisierung zentral durchgeführt kann die Individualisierung vor dem Vereinzeln stattfinden. Eine Ausführungsform sieht somit vor, dass der Laminationskörper in mehrere Sicherheitsdokumentenrohlinge aufgeteilt wird, die jeweils mindestens einen der mehreren Markierungsbereiche aufweisen.Preferably, a multiple benefit is divided into individual security document blanks prior to individualization. If individualization is carried out centrally, individualization can take place before separation. One embodiment thus provides for the lamination body to be divided into a plurality of security document blanks, each of which has at least one of the plurality of marking areas.
Bei einer Ausführungsform werden die Vertiefungen des Markierungsbereichs mit unterschiedlichen Tiefen bezogen auf einen ebenen glatten Bereich der Außenfläche eingeprägt, welcher den Markierungsbereich mit der Vielzahl der Vertiefungen umlaufend umgibt. Der Anteil der in die Vertiefungen gedruckten oder zu druckenden Informationen, wird somit in Unterschiedlichen Ebenen oder Tiefen des Dokuments bezogen auf die Außenfläche des Sicherheitsdokumentenrohlings eingebracht und gespeichert. Dieses erschwert bei einer Fälschung insbesondere das Entfernen der alten, zu manipulierenden Informationen.In one embodiment, the recesses of the marking area are impressed with different depths with respect to a flat smooth area of the outer surface, which surrounds the marking area with the plurality of recesses circumferentially. The proportion of information printed or to be printed in the recesses is thus introduced and stored at different levels or depths of the document relative to the outer surface of the security document blank. In the case of counterfeiting, this makes it particularly difficult to remove the old information that has to be manipulated.
Bei einer Ausgestaltung ist vorgesehen, dass eine Tiefe der Vertiefungen bezogen auf einen ebenen glatten Bereich der Außenfläche, welcher den Markierungsbereich mit der Vielzahl der Vertiefungen umlaufend umgibt, zwischen 30µm und 200 µm, bevorzugter zwischen 50 µm und 150 µm beträgt.In one embodiment, it is provided that a depth of the recesses with respect to a flat smooth area of the outer surface, which circumferentially surrounds the marking area with the plurality of recesses, is between 30 μm and 200 μm, more preferably between 50 μm and 150 μm.
Besonders bevorzugt wird zumindest ein Teil der Vertiefungen mit einer Tiefe, bezogen auf einen ebenen glatten Bereich der Außenfläche, welcher den Markierungsbereich mit der Vielzahl der Vertiefungen umlaufend umgibt, eingeprägt, die größer oder gleich einer Substratschichtstärke der Substratschicht ist, aus welcher die äußere Oberfläche des Laminationskörpers gebildet wird. Hierdurch wird es erforderlich mindesten die gesamte äußere Materialschicht bei einer Manipulation erheblich zu beschädigen, oder ganz zu entfernen. Dieses erschwert eine Fälschung enorm.More preferably, at least a portion of the recesses having a depth, with respect to a flat smooth portion of the outer surface surrounding the marking region with the plurality of recesses, imprinted, which is greater than or equal to a substrate layer thickness of the substrate layer, from which the outer surface of the Laminating body is formed. This will require at least the entire outer layer of material to be significantly damaged during a manipulation, or completely removed. This hampers a fake enormously.
Um ein Nachbilden der äußeren Oberfläche des Sicherheitsdokuments oder des Sicherheitsdokumentenrohlings weiter zu erschweren, ist bei einer Ausführungsform vorgesehen, dass beim Einprägen der Mikrostrukturierung zusätzlich Vorsprünge in dem Markierungsbereich in der Außenfläche erzeugt werden, wobei die Vorsprünge gegenüber einem Niveau der Außenfläche des Laminationskörpers außerhalb des Markierungsbereichs, der eben und glatt ausgebildet ist und den Markierungsbereich umlaufend umgibt, vorspringen. Nach wie vor umfasst der Markierungsbereich auch noch die Vielzahl der Vertiefungen, die gegenüber dem Niveau der Außenfläche des Laminationskörpers außerhalb des Markierungsbereichs vertieft sind, das heißt, in den Laminationskörper hineinragen. Vorsprünge lassen sich beispielsweise ohne ein Erwärmen der äußeren Materialschicht zumindest im Bereich des Markierungsbereichs auf eine Temperatur nahe der Glastemperatur des Kunststoffmaterials der äußeren Materialschicht oder sogar auf eine Temperatur oberhalb der Glastemperatur nicht ausbilden. Insbesondere schieden Kaltprägeverfahren und Laserablationsverfahren zum Ausbilden der Vertiefungen aus, da mit diesen Verfahren keine Vorsprünge realisiert werden können.In order to further complicate replicating the outer surface of the security document or security document blank, in one embodiment provided that in the embossing of the microstructuring in addition projections are produced in the marking area in the outer surface, wherein the projections against a level of the outer surface of the lamination body outside the marking area, which is formed flat and smooth and surrounding the marking area circumferentially, projecting. As before, the marking area also includes the plurality of depressions that are recessed from the level of the outer surface of the lamination body outside the marking area, that is, project into the lamination body. For example, without heating the outer material layer at least in the region of the marking region, protrusions can not be formed to a temperature close to the glass transition temperature of the plastic material of the outer material layer or even to a temperature above the glass transition temperature. In particular, cold-stamping methods and laser ablation methods for forming the pits have been eliminated since projections can not be realized with these methods.
Bei einer Ausführungsform ist vorgesehen, dass zumindest der Anteil, der individualisierenden Informationen pixelgenau mittels einer Zubereitung in die Vertiefungen gedruckt wird. Bei einer solchen Ausführungsform kann die gesamte Individualisierungsinformation pixelgenau in die Vertiefungen gedruckt werden. In einem solchen Fall ist die äußere Materialschicht vorzugsweise transparent und farbneutral ausgebildet.In one embodiment it is provided that at least the portion of the individualizing information is printed pixel by pixel into the depressions by means of a preparation. In such an embodiment, the entire customization information can be printed pixel-precise in the wells. In such a case, the outer material layer is preferably transparent and neutral in color.
Ebenso ist es bei anderen Ausführungsformen möglich, dass die Individualisierungsinformation vollflächig auf den Markierungsbereich aufgebracht wird, so dass ein Teil der Individualisierungsinformationen auf die Außenfläche aufgedruckt wird und ein Teil der Individualisierungsinformationen in die Vertiefungen gedruckt wird. Die einzelnen Informationsbestandteile, beispielsweise Bestandteile eines Gesichtsbildes, sind dann korreliert zueinander in unterschiedlichen Ebenen des fertigen Sicherheitsdokuments gespeichert. Dies kann zu Verifikationszwecken des Sicherheitsdokuments genutzt werden. Selbst wenn der auf die Außenfläche aufgebrachte Informationsanteil, welcher einer Manipulation leichter zugänglich ist, verfälscht wird, ist dies dadurch feststellbar, dass die Korrelation zwischen dem Anteil, der auf der Außenfläche aufgebracht ist, und dem Anteil der Individualisierungsinformationen, der in die Vertiefungen gedruckt ist, nicht mehr vollständig existiert.Likewise, in other embodiments it is possible for the individualization information to be applied over the entire area to the marking region, so that part of the individualization information is printed on the outer surface and a part of the individualization information is printed in the depressions. The individual information components, for example components of a facial image, are then stored correlated to one another in different levels of the finished security document. This can be used for verification purposes of the security document. Even if the information portion applied to the outer surface, which is more easily accessible to manipulation, is distorted, it can be detected by the correlation between the proportion deposited on the outer surface and the proportion of the individualization information printed in the recesses , no longer completely exists.
Die Individualisierungsinformation kann auch in der Weise teilflächig auf den Markierungsbereich aufgebracht werden, so dass ein Teil der Individualisierungsinformationen auf die Außenfläche aufgedruckt wird und ein Teil der Individualisierungsinformationen in die Vertiefungen gedruckt wird, jedoch ein Teil der Außenfläche unbedruckt bleibt. Bei manchen Ausführungsformen bleibt auch eine Informationsschicht im Bereich einiger Vertiefungen unbedruckt.The individualization information can also be applied in part to the marking area in the manner that part of the individualization information is printed on the outer surface and a part of the individualization information is printed in the wells, but a part of the outer surface remains unprinted. In some embodiments, an information layer remains unprinted in the region of some depressions.
Besonders bevorzugt wird die Individualisierungsinformation mittels eines Tintenstrahldruckverfahrens mittels einer oder mehrerer Zubereitungen aufgedruckt. Tintenstrahldruckeinrichtungen sind in der Lage, gezielt einzelne Pixel in einer vorgewählten Farbe mittels einer Zubereitung zu drucken. Hierüber ist möglich, beispielsweise pixelgenau die Zubereitung in die einzelnen Vertiefungen zu drucken. Darüber hinaus ist es durch die Verwendung von drei Zubereitungen, welche jeweils im verdruckten Zustand den Farbeindruck einer Primärfarbe hervorrufen, möglich, vollfarbige Individualisierungsinformationen aufzudrucken, wobei über eine Farbsubtraktion sämtliche Farbeindrücke in einem durch die Primärfarben aufgespannten Gamut zur Darstellung der Individualisierungsinformationen nutzbar sind.Particularly preferably, the individualization information is printed by means of an inkjet printing process by means of one or more preparations. Inkjet printing devices are capable of selectively printing individual pixels in a preselected color by means of a formulation. This makes it possible, for example, to print the preparation in the individual wells with pixel accuracy. In addition, it is possible by the use of three preparations, which each produce the color impression of a primary color in the printed state, full color individualization information, a color subtraction all color impressions in a spanned by the primary colors gamut for displaying the customization information can be used.
Besonders bevorzugt werden zum Bedrucken jedoch Tintenstrahldruckeinrichtungen, in denen zusätzlich zu den Farbzubereitungen, welche einen Farbeindruck einer Primärfarbe vermitteln, weitere Zubereitungen genutzt werden, die beispielsweise einen schwarzen Farbeindruck hervorrufen oder zusätzlich weitere nicht in dem Gamut liegende Farbeindrücke hervorrufen können.However, inkjet printing devices are particularly preferred for printing, in which, in addition to the color preparations, which convey a color impression of a primary color, further preparations are used which, for example, produce a black color impression or additionally can cause further color impressions not lying in the gamut.
Besonders vorteilhaft ist es, wenn die Individualisierungsinformation mit einem Sicherheitsdruck kombiniert wird, der bei der Herstellung des Laminationskörpers auf eine Informationsschicht aufgebracht ist. Besonders bevorzugt wird somit der Dokumentkörper mit einem Sicherheitsdruck auf einer Informationsschicht bereitgestellt und die Vertiefungen so ausgebildet, dass diese eine Tiefe aufweisen, die der Materialschichtstärke der äußeren Materialschicht entspricht. Der Anteil der Individualisierungsinformationen, der durch die Vertiefungen hindurch auf die Informationsschicht aufgedruckt wird, wird somit mit dem Sicherheitsdruck auf der Informationsschicht verbunden. Sollte es einem Fälscher gelingen, Anteile der auf die Informationsschicht aufgedruckten Individualisierungsinformationen zu entfernen, so führt dies ebenfalls zu einer Veränderung und/oder Beschädigung des Sicherheitsdrucks. Um den Sicherheitsdruck im überdruckten Bereich erkennen zu können, können beispielsweise Zubereitungen verwendet werden, welche im verdruckten Zustand transluzent oder transparent sind, so dass Teile des Sicherheitsdrucks trotz einer Überdruckung durch die Individualisierungsinformationen hindurch nach wie vor wahrnehmbar ist.It is particularly advantageous if the individualization information is combined with a security print which is applied to an information layer during the production of the lamination body. The document body is thus particularly preferably provided with a security print on an information layer, and the depressions are formed such that they have a depth which corresponds to the material layer thickness of the outer material layer. The proportion of the individualization information printed on the information layer through the pits is thus linked to the security print on the information layer. If a counterfeiter succeeds in removing portions of the individualization information printed on the information layer, this likewise leads to a change and / or damage to the security printing. Around For example, preparations can be used which are translucent or transparent in the printed state, so that parts of the security print can still be perceived despite the overprinting by the individualization information.
Eine besonders gute Verbindung mit dem Sicherheitsdruck stellt sich ein, wenn Zubereitungen verwendet werden, deren Farbmittel zumindest teilweise in das Material eindiffundieren, auf welches diese aufgedruckt werden. Bei einer Ausführungsform werden daher die Individualisierungsinformationen mittels mindestens einer Zubereitung gedruckt, welche ein Lösungsmittel umfasst, welches das Material der äußeren Materialschicht und/oder der Informationsschicht angreift, so dass ein Eindiffundieren der Farbmittel der Zubereitung in die Wände der Vertiefungen in der äußeren Materialschicht und/oder die Informationsschicht begünstigt wird. Eine untrennbare Verbindung zwischen der aufgedruckten Individualisierungsinformation und der jeweiligen die Information aufnehmenden Materialschicht kann auch dadurch oder zusätzlich erreicht werden, dass die Zubereitung auf Basis desselben Kunststoffmaterials hergestellt ist, aus dem die jeweilige Materialschicht oder die Materialschichten hergestellt sind.A particularly good connection with the security printing arises when preparations are used whose colorants at least partially diffuse into the material on which they are printed. In one embodiment, therefore, the individualization information is printed by means of at least one preparation which comprises a solvent which attacks the material of the outer material layer and / or the information layer so that the colorants of the preparation diffuse into the walls of the depressions in the outer material layer and / or or the information layer is favored. An inseparable connection between the printed individualization information and the respective material layer receiving the information can also be achieved by or in addition to the fact that the preparation is produced on the basis of the same plastic material from which the respective material layer or layers are made.
Beispielsweise eignen sich bei einer Verwendung von Polycarbonaten für die Informationsschicht und die äußere Materialschicht Zubereitungen, die auf Basis von Polycarbonat hergestellt sind. Solche Zubereitungen sind beispielsweise in der
Die
Hinsichtlich der konkreteren Ausgestaltung wird auf die zitierte Offenlegungsschrift verwiesen, die hiermit vollumfänglich als Bestandteil dieser Anmeldung aufgenommen wird.With regard to the more concrete embodiment, reference is made to the cited published patent application, which is hereby incorporated in its entirety as part of this application.
Um ein Eindringen der Zubereitung in die Vertiefungen und hin zu der Informationsschicht zu begünstigen, sind die Vertiefungen bei einer Ausführungsform so ausgebildet, dass diese sich konisch von der Außenfläche des Laminationskörpers zu der Informationsschicht hin verfügen.In one embodiment, to promote penetration of the formulation into the wells and toward the information layer, the wells are formed to conically extend from the outer surface of the lamination body to the information layer.
Besonders bevorzugt wird die Individualisierungsinformation vollfarbig gedruckt. Besonders bevorzugt umfasst die Individualisierungsinformation ein Gesichtsbild eines Nutzers, dem das Sicherheitsdokument zugeordnet ist oder wird.Particularly preferably, the individualization information is printed in full color. Particularly preferably, the individualization information comprises a facial image of a user to whom the security document is or will be assigned.
Um die auf die Außenfläche aufgedruckte Individualisierungsinformation vor Manipulation und/oder Beschädigung zu schützen, wird bei einer bevorzugten Ausführungsform auf die Außenfläche nach dem Aufdrucken der Individualisierungsinformation, die zumindest teilweise in die Vertiefungen auf die Informationsschicht im Inneren des Laminationskörpers gedruckt wird, eine Abdeckschicht oder Substratschicht aufgebracht. Diese kann beispielsweise als Lackschicht aufgebracht werden und ausgebildet sein. Vorzugsweise wird hierfür ein transparenter farbneutraler Lack verwendet. Ebenso ist es möglich eine transparente Folie auf den Laminationskörper aufzulaminieren. In der Regel lassen sich jedoch nicht die Drücke oder Temperaturen erreichen, die notwendig wären, um eine monolithische Verbindung der äußeren Schutzschicht mit dem Rest des mittels des Dokumentrohlings bereitgestellten Laminationskörpers zu erreichen. Die mit Vertiefungen versehene äußere Materialschicht begünstigt zusätzlich die Verbindung der äußeren Schutzschicht mit dem Laminatkörper. Lack bzw. Kleber können in die Öffnungen eindringen. Dadurch vergrößert sich die Verbindungsfläche. Das Eindringen von Lack bzw. Kleber in die Vertiefungen verhindert das nachträgliche Überdrucken der Individualisierungsinformation in den Vertiefungen.In order to protect the customization information printed on the outer surface from tampering and / or damage, in a preferred embodiment, a cover layer or substrate layer is applied to the outer surface after printing the customization information printed at least partially in the recesses on the information layer inside the lamination body applied. This can be applied, for example, as a lacquer layer and be formed. Preferably, a transparent color-neutral lacquer is used for this purpose. It is also possible to laminate a transparent film on the lamination body. However, as a rule, the pressures or temperatures that would be necessary to achieve a monolithic bond of the outer protective layer to the remainder of the lamination body provided by the document blank can not be achieved. The recessed outer material layer additionally favors the bonding of the outer protective layer to the laminate body. Paint or glue can penetrate into the openings. This increases the connection area. The penetration of paint or adhesive in the wells prevents the subsequent overprinting of the customization information in the wells.
Neben den oben beschriebenen Vertiefungen, die sich konisch von der Außenfläche zur Informationsschicht hin verfügen, ist bei einigen Ausführungsformen auch eine andere Geometrie für die Vertiefungen vorgesehen. Diese Vertiefungen können eine zylindrische Form aufweisen. Im Hinblick auf eine Querschnittsform parallel zur Außenfläche können die Vertiefungen kreisrund, oval, dreieckig, quadratisch, vieleckig, z.B. sternförmig, sechseckig usw. ausgebildet sein. Die verschiedenen Querschnittsformen und Geometrien können beliebig miteinander kombiniert werden. In einem Laminationskörper können Vertiefungen unterschiedlicher Gestalt miteinander kombiniert werden.In addition to the indentations described above, which are tapered from the outer surface to the information layer, in some embodiments, a different geometry is also provided for the indentations. These recesses may have a cylindrical shape. With regard to a cross-sectional shape parallel to the outer surface, the depressions may be circular, oval, triangular, square, polygonal, eg star-shaped, hexagonal, etc. be formed. The various cross-sectional shapes and geometries can be combined as desired. In a lamination body pits of different shapes can be combined.
Bei den so hergestellten und individualisierten Sicherheitsdokumenten kann es sich einerseits um Sicherheitsdokumente handeln, welche als Kunststoffkarten ausgebildet sind. Ebenso können jedoch auch Sicherheitsdokumente auf diese Weise personalisiert werden, die beispielsweise als Passbuch ausgebildet sind, in welches ein Laminationskörper als eine Seite eingebunden ist.The individualized security documents produced in this way can be, on the one hand, security documents which are designed as plastic cards. Likewise, however, security documents can be personalized in this way, which are designed for example as passport book, in which a lamination body is integrated as a page.

Eine äußere Substratschicht 3 ist zumindest in einem für eine spätere Individualisierung vorgesehenen Bereich 7 vorzugsweise transparent und farbneutral.An
An die äußere Substratschicht 3 angrenzend ist in dem Stapel 1 ist bei der gezeigten Ausführungsform eine sogenannte Informationssubstratschicht 5 angeordnet.

Der Sicherheitsdruck 6 kann vollfarbig ausgeführt sein.Adjacent to the

Die Vertiefungen 14 weisen vorzugsweise Durchmesser 22 in der Größenordnung von 100 µm bis 400 µm auf, besonders bevorzugt im Bereich von 150 µm bis 300 µm. Die Vertiefungen 14 sind vorzugsweise in einem regelmäßigen bzw. bestimmten Raster angeordnet. Bei einigen Ausführungsformen sind die Vertiefungen so angeordnet, dass diese gemeinsam über ihre Anordnung ein Muster, z.B. ein Logo, Schriftzeichen oder Ähnliches darstellen. Die Abstände 23 von Mittelpunkten 24 liegen vorzugsweise im Bereich von 120 bis 1000 µm, besonders bevorzugt im Bereich von 500 µm, bei einem Durchmesser 22 der Vertiefungen 14 von 150 µm. Die dargestellten Öffnungsgrößen und Abstände sind nicht maßstabsgerecht. Eine Substratschichtstärke 27 der äußeren Substratschicht 3 liegt vorzugsweise im Bereich zwischen 50 µm und 200 µm, vorzugsweise im Bereich von etwa 50 µm bis 100 µm.The
In einem Markierungsbereich 17 wird auf eine Außenfläche 19 des Laminationskörpers 11 eine Individualisierungsinformation 18 aufgedruckt. Dies erfolgt vorzugsweise mittels eines Digitaldruckverfahrens, insbesondere eines Tintenstrahldruckverfahrens. Einzelne Bildpunkte werden mit unterschiedlichen Zubereitungen auf die Außenfläche 19 des Laminationskörpers 11 gedruckt. Ein Teil der Individualisierungsinformation 18-1 wird hierbei auf die Informationsschicht 15 durch die Vertiefungen 14 hindurchgedruckt. Dies bedeutet, dass die verwendete Zubereitung in die Vertiefungen 14 eindringt und beispielsweise mittels eines Kapillareffekts zu der Informationsschicht 15 hingeleitet wird. Dort verbindet sich somit ein Teil 18-1 der Individualisierungsinformation 18 mit dem Sicherheitsdruck 16. Ein weiterer Teil 18-2 der Individualisierungsinformation verbleibt auf der Außenfläche 19 quasi auf den Stegen zwischen den Vertiefungen 14. Die Individualisierungsinformation 18 wird somit in zwei unterschiedlichen Ebenen des Laminationskörpers 11 gespeichert.In a
Bei einer Ausführungsform wird der eine Teil 18-1 der Individualisierungsinformation pixelgenau in die Vertiefungen 14 gedruckt. Bei einer Ausführungsform kann vorgesehen sein, dass nur der eine Teil 18-1, welcher pixelgenau in die Vertiefungen 14 gedruckt wird, als Individualisierungsinformation 18 verwendet wird. Hierbei existieren somit keine Informationsanteile, die auf der Außenfläche 19, d.h. den Stegen zwischen den Vertiefungen 14 verbleibt.In one embodiment, the one part 18-1 of the individualization information is printed in the
Die verwendeten Zubereitungen können vorzugsweise so ausgestaltet sein, dass der sich ergebende Farbeindruck der gesamten Individualisierungsinformation 18 vollfarbig ist. Die Zubereitungen umfassen somit vorzugsweise mindestens drei Zubereitungen, die im verdruckten Zustand jeweils einen Farbeindruck einer Primärfarbe eines Farbsystems bei einem menschlichen Betrachter hervorrufen. Darüber hinaus sind die Zubereitungen vorzugsweise so ausgebildet, dass die ausgebildeten Bildpunkte, insbesondere im Bereich der Vertiefungen 14 transluzent sind, so dass ein Teil des Sicherheitsdrucks 16 auch im Bereich der Vertiefungen 14 durch den Teil der Individualisierungsinformation 18-1 erkennbar bleibt, der auf die Informationsschicht 15 gedruckt ist. Hierdurch wird eine optimale Verbindung der Individualisierungsinformation 18 mit dem Sicherheitsdruck 16 erreicht.The preparations used may preferably be designed so that the resulting color impression of the
Insbesondere ist es vorteilhaft, wenn die äußere Materialschicht 13 transparent und farbneutral ausgebildet ist, so dass der Sicherheitsdruck durch die Außenfläche 19 betrachtbar ist. Dieses gilt zumindest für die Bereiche, die nicht opak bedruckt sind.In particular, it is advantageous if the
Vorzugsweise werden Zubereitungen verwendet, die einen Lösungsmittelanteil enthalten, der den Kunststoff der äußeren Materialschicht 13 und/oder der Informationsschicht 15 anlöst. Hierdurch wird eine Diffusion von Farbmitteln der Zubereitung in das Material der äußeren Materialschicht 13, eventuell einschließlich der Wände 26 der Vertiefungen 14, und der Informationsschicht 15 unterstützt und/oder herbeigeführt.Preferably, preparations are used which contain a solvent portion which dissolves the plastic of the
Um eine gute Verbindung der Individualisierungsinformation 18, insbesondere mit dem Sicherheitsdruck 16, zu erreichen, sind die Zubereitungen vorzugsweise auf Basis des Kunststoffmaterials hergestellt, aus dem die äußere Materialschicht 13 und/oder die Informationsschicht 15 hergestellt wird.In order to achieve a good connection of the

Um die aufgebrachte Individualisierungsinformation 18, insbesondere den weiteren Teil 18-2, der auf der Außenfläche 19 des Laminationskörpers 11 gespeichert ist, vor mechanischer Beschädigung und/oder einer Manipulation zu schützen, wird auf die Außenfläche 19 eine Lackschicht 40 aufgebracht, welche so aufgebracht werden kann, dass die Vertiefungen 14 mit dem Lack verfüllt werden. Hierdurch ergibt sich eine glatte Oberfläche des fertigen Dokumentenkörper 80. In der dargestellten Ausführungsform ist der Dokumentenkörper 80 selbst das Sicherheitsdokument 90. Bei anderen Ausführungsformen kann der Dokumentenkörper 80 in ein Passbuch eingenäht sein, welches das fertige Sicherheitsdokument darstellt.In order to protect the applied
