Definitions
- the present invention relates to a value or security product, in particular an identity card, and a method for its production.
- value or security documents can be, for example, an ID document, a check card, a non-personalized authorization pass, such as a ticket or a means of payment, or a value or security element intended for product protection.
- Valuable or security products in particular valuable or security documents, are used to verify the identity of a person or thing or a claim, for example for the payment of a sum of money or for the surrender of an item or the provision of a service. To this end, it must be ensured that the value or security product cannot be imitated, counterfeited or falsified, or only with considerable effort.
- the valuable or security product therefore contains security elements or security features which are extremely difficult or even practically impossible to imitate.
- the value or security product such as banknotes, consists of a material that is not readily available.
- security features can be formed by special colors, for example luminescent or optically variable colors, optical elements such as holograms, tilting images, kinegrams, lens or prism arrays, also guilloches, mottled fibers, security threads and others.
- One way to secure the portrait image of an identity card is to not pre-publish it DE 10 2019 124 762 A1 to be taken from the applicant. This has proven itself well. From the DE 10 2018 106 430 A1 the applicant is aware of a value or security product according to the preamble of claim 1, which comprises a security element with a micro- or nanostructure whose structure is formed as a function of personal data present on the document. This security document has proven itself well and is very forgery-proof.
- the value or security product according to the invention in particular the identity card, has in particular a multi-layer structure which has at least one printed layer with personal data in the form of text elements and/or graphic elements and/or laser markings and at least one micro- or nanostructured security element with a structure includes, which is selected depending on at least one piece of information from the personal data.
- the structure itself and/or a shape of the structure of the security element is selected as a function of at least one further parameter.
- the resilience of the value or security product, in particular its surface is improved, since the linking of a first basic structure and a further personalized and/or non-personalized basic structure can limit areas with a high density of structural elements . Furthermore, there is an improvement in the perceptibility and inspectability of the security element formed by the microstructure or nanostructure.
- the value or security product is in ID 1, ID 2, ID 3 or any other format, for example in booklet form, like a passport-like item.
- the value or security product is generally a laminate of several document layers, which are connected to one another with a precise fit under the action of heat and increased pressure. These products should meet the standardized requirements, for example ISO 10373, ISO/IEC 7810, ISO 14443.
- the product layers preferably consist of a carrier material that is suitable for lamination.
- the product of value or security can preferably be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminally disubstituted bis(hydroxyphenyl)cycloalkane, polyethylene terephthalate (PET), their derivatives such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS) , polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and derivatives thereof
- the valuable or security product can also be made from several of these materials. It preferably consists of PC, PVC and PET.
- the polymers can be either filled or unfilled. In the latter case, they are preferably transparent or translucent. If the polymers are filled, they are opaque.
- the above information relates both to films to be bonded together and to liquid formulations that are applied to a preliminary product, such as a protective coating or top coat.
- the valuable or security product is preferably produced from three to twelve, preferably four to ten, films.
- the films can also carry printed layers. A laminate formed in this way can finally be coated on one or both sides with the protective or top coat or with a film.
- the foil can in particular be a volume hologram, a foil with a surface hologram (for example a kinegraphic element) or a scratch protection foil.
- Overlay layers formed in this way protect a security feature arranged underneath and/or give the document the required abrasion resistance.
- the security element is formed areally with a high density of structural elements of more than 500 DPI ("dots per inch"), preferably of at least 900 DPI to 1200 DPI.
- the structure is present in particular as hatching, which is configured very precisely.
- surfaces can be formed which have a very high density of structural elements, but which can be sharply delimited by superimposing the information from the at least one further parameter.
- This limitation can be caused, for example, by the structure of the security element being determined from the logical combination of the personal data and the at least one further parameter.
- a large part of the document surface is advantageously provided with the structure of the security element. This can be done, for example, by a sinusoidal or sine wave-shaped, in particular planar design in the form of a Beat as a result of an algorithm, in particular an algorithm with at least two parameters.
- the security against counterfeiting is additionally increased if not only personal text elements are used to protect the value or security document with the structural element, but if the structure contains at least one piece of information from a graphic element, which comes from the portrait of the owner of the valuable or security product, for example .
- the complete facial image alternatively just the shape of the head, can also be used as the basis for forming the structure of the security element.
- Improved protection against counterfeiting of the value or security product can also be achieved in that the additional parameter flowing into the structure is formed by additional personal information from the at least one printed layer and/or laser markings.
- additional personal information from the at least one printed layer and/or laser markings.
- the security element is introduced into a cover layer in such a way that the structured areas contrast strongly with the structure-free areas when viewing reflected light, especially when reflected at the glancing angle, and the structures introduced are thus clearly recognizable.
- the security element is introduced into a cover layer in such a way that the structured areas contrast strongly with the structure-free areas when viewing transmitted light and the structures introduced are thus clearly recognizable. This improves the visibility and verifiability of the security feature.
- the value or security document can also have a number of micro- or nanostructured security elements.
- the structure or part of the structure of the security element is thus continued, as a result of which increased visibility and greater coverage or protection of the document surface can be achieved.
- personalized data is linked to data from another structure in such a way that the resulting security element produced by micro- or nanostructuring retains the resilience of the document surface concerned and the visibility and verifiability of the security element or security feature is improved.
- the security element is preferably formed areally with a high structure element density of more than 500 DPI ("dots per inch"), with the structure of the security element preferably being determined from a logical combination of the personal data and the at least one other parameters.
- the personal data and the at least one further parameter run through an algorithm, by which, for example, a beat is formed from the personal data and the at least one further parameter on which the structure of the security element is based.
- the resulting "envelope” thus forms a "sharp" boundary between a structured area and an unstructured area.
- the structure is preferably in the form of hatching, which is designed very precisely and thus covers a larger area.
- the information flowing into the structure is a graphic element in the form of a portrait image, in particular a portrait image of the owner. Protection against forgery is also increased by the fact that the additional parameter flowing into the structure is formed by additional personal information from the at least one printed layer and/or laser markings, for which personal data of a text element can be used, for example. Personal text elements such as the date of birth, the name, the place of residence or the like can therefore be used for the further parameter.
- the security element is introduced into a cover layer, whereby the structured areas have a stronger contrast when viewing reflected light, especially when reflected in the glancing angle, compared to the unstructured areas and thus the introduced areas structures are clearly visible.
- the structured areas have a stronger contrast when viewing transmitted light compared to the structure-free areas and the introduced structures are thus clearly recognizable.
- the logical linking of the personalized data and the further parameter also creates a "sharp" boundary between the structured and unstructured area, which means that the security feature can be checked more easily.
- a laser can be used to form the structure.
- a frequency-multiplied solid-state laser for example, can be used as a laser, although excimer lasers and fiber lasers can also be used. These lasers are characterized by their positive property of being able to be operated in a very wide range of possible outputs, so that a desired energy input into the irradiated material can be specified or freely selected.
- a pulsed mode of the laser powerful but short-term energy pulses can be introduced into the material so that it is removed without burning and without leaving traces of smoke.
- the use of a picosecond laser or a femtosecond laser is particularly preferred for the introduction of powerful laser pulses with a low heat input into the material.
- the value or security document 100 can be a personal document such as a passport, an identity card, an access card or the like, a check card or a banknote or something else document, be. All of the following examples are described using such a card as representative of other document types.
- the value or security product 100 is shown in the form of an identity card, which has been assembled, for example, as a laminate of a plurality of internal polymer layers 140.
- the polymer layers can consist of PC and/or PET.
- the individual layers can be unfilled or filled with fillers. In the latter case they are opaque, otherwise transparent.
- the plies may preferably be bonded together to form a monolithic block that is practically impossible to split.
- the card's optional outer layers 150 may be formed as a final protective plastic film or consist of a protective varnish applied to the card after lamination.
- the plastic protective film or the protective varnish is transparent so that the information underneath is visible from the outside.
- one or more printed layers 142 for example of a portrait image 110, remain visible, which is or are preferably arranged directly next to or behind the optional outer layer 150.
- the valuable or security product 100 has an upper side 101 and an underside 102 .
- the facial or portrait image 110 of the owner of the card and data fields namely for example a first data field 120 and a second data field 130 with card and owner data in plain text, are located on the upper side 101 .
- the data in the first and second data fields 120, 130 is produced by printing layers and/or laser markings lying on an outer layer of the document but immediately below the optional outer protective layer 150.
- a security feature or security element 500 is assigned to the portrait image 110 for its protection, which comprises a microstructured or nanostructured structure 502 that was introduced by means of a laser, for example.
- this security element 500 is formed in an areal manner with a high structure density of more than 500 DPI ("dots per inch").
- this planar construct is preferably present with a structural element density of 900 dpi to 1200 dpi. An even higher resolution is also possible.
- the structure 502 of the security element 500 has the special feature that it is selected on the one hand depending on at least one piece of information from the personal data.
- the structure 502 itself and/or a shape of the structure 502 of the security element 500 is selected as a function of at least one other parameter, so that there is an overlay of information that influences the shape and/or the dimensions of the structure 502, whereby increased protection against counterfeiting for the value or security product 100 results.
- the structure 502 has thus been determined from a logical combination of the personal data and the at least one further parameter.
- FIG 3 clarifies this superimposition even more clearly.
- personal information of a graphic element in the form of the portrait image 110 flows into the structure 502 on the one hand.
- at least one piece of additional information flows into the structure 502 , for example in the form of an overlay structure 506 obtained from additional personal data of the value or security product 100 .
- This additional personal information can be, for example, the date of birth, place of residence, name, etc. of the owner of the identity card.
- an algorithm is used, for example, which generates the structure 502 in the form of a beat from the portrait image 110 and the at least one other parameter, which then forms the security element 500, which can then be applied, or which can then be laser-inserted into the cover layer 150 registered becomes.
- This logical linking (overlaying) of a first personalized basic structure and a further personalized or non-personalized basic structure not only allows areas with a high density of structural elements to be produced, but also to delimit them.
- the structure is preferably in the form of very precise hatching, which forms a surface as it were.
- the security element 500 is introduced into a cover layer 150 or is attached thereto in such a way that the structured areas contrast strongly with the structure-free areas when viewing transmitted light and the structures introduced are thus clearly recognizable.
- the structured surfaces also contrast strongly when looking at reflected light, especially with reflection in the glancing angle, compared to the structure-free areas and are therefore easily recognizable as introduced structures.
- the portrait image 110 is more clearly visible in those with structure 502 provided areas than is the case for areas not provided with structure 502.
- the security element 500 can also be continued, for example in the form of a beat, and thus the continuation 504 covers or secures a large part of the surface.
- a method for verifying the authenticity of the security element 500 and thus of the value or security product 100 is disclosed—only by way of example.
- the structure 502 to be checked is overlaid with a control structure 602 which also results from the (adapted) algorithm for generating the structure 502 . It can also be a "negative" of the structure 502 to be tested. If the structure 502 to be checked is unadulterated, then the logical combination of the structure 502 with the control structure 602 of the test element 600 results in an area without residues (shown on the bottom left). If the structure 502 to be checked is a forgery or modification, the overlay with the control structure 602 results in easily recognizable residues (shown at the bottom right).
- Security element 500 can also be formed by individualizing, personal data, the control structure 602, whereby the protection against forgery is additionally increased.

Beispielsweise besteht das Wert- oder Sicherheitsprodukt , wie Banknoten, aus einem nicht ohne weiteres verfügbaren Material. Zusätzlich oder alternativ können Sicherheitsmerkmale durch spezielle Farben, beispielsweise lumineszierende oder optisch variable Farben, optische Elemente, wie Hologramme, Kippbilder, Kinegramme, Linsen- oder Prismenarrays, ferner Guillochen, Melierfasern, Sicherheitsfäden und andere gebildet sein.Valuable or security products, in particular valuable or security documents, are used to verify the identity of a person or thing or a claim, for example for the payment of a sum of money or for the surrender of an item or the provision of a service. To this end, it must be ensured that the value or security product cannot be imitated, counterfeited or falsified, or only with considerable effort. The valuable or security product therefore contains security elements or security features which are extremely difficult or even practically impossible to imitate. For example, the value or security product, such as banknotes, consists of a material that is not readily available. Additionally or alternatively, security features can be formed by special colors, for example luminescent or optically variable colors, optical elements such as holograms, tilting images, kinegrams, lens or prism arrays, also guilloches, mottled fibers, security threads and others.
Obwohl viele zur Anwendung kommende Sicherheitsmerkmale oder Sicherheitselemente existieren, sind noch immer viele Fälschungen von Wert- oder Sicherheitsprodukten erfolgreich; insbesondere solche, bei denen ein auf dem Wert- oder Sicherheitsprodukt angebrachtes Portrait nachträglich gefälscht oder verfälscht worden ist. Die teilweise oder vollständige Manipulation des vorhandenen Portraits, geschieht durch nachträgliche Übermalung auf einer dünnen Folie, welche über das Wert- und Sicherheitsprodukt aufgezogen wird, um die Fälschung für das menschliche Auge - zumindest weitgehend - unsichtbar zu machen.Although there are many security features or security elements in use, many counterfeiting of value or security products are still successful; in particular those in which a portrait attached to the value or security product has subsequently been forged or falsified. The partial or complete manipulation of the existing portrait is done by subsequent overpainting on a thin foil, which is pulled over the valuable and security product in order to make the forgery invisible to the human eye - at least to a large extent.
Eine Möglichkeit zur Absicherung des Portraitbilds einer Identitätskarte ist der nicht vorveröffentlichten
Es ist die Aufgabe der vorliegenden Erfindung, ein Wert- oder Sicherheitsprodukt sowie ein Verfahren zu dessen Herstellung anzugeben, die zu einer Verbesserung der Widerstandsfähigkeit sowie zu einer erhöhten Fälschungssicherheit führen.It is the object of the present invention to specify a valuable or security product and a method for its production, which lead to an improvement in resistance and to increased security against forgery.
Diese Aufgabe wird mit einem Wert- oder Sicherheitsprodukt mit dem Merkmalsbestand des Anspruchs 1 sowie einem Verfahren mit dem Merkmalsbestand des Anspruchs 9 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved with a value or security product having the features of claim 1 and a method having the features of claim 9 . Advantageous configurations with expedient developments of the invention are specified in the dependent claims.
Das erfindungsgemäße Wert- oder Sicherheitsprodukt, insbesondere die Identitätskarte, weist insbesondere einen mehrschichtigen Aufbau auf, der wenigstens eine Druckschicht mit personenbezogenen Daten in Form von Textelementen und/oder Grafikelementen und/oder Lasermarkierungen sowie wenigstens ein mikro- oder nanostrukturiertes Sicherheitselement mit einer Struktur umfasst, welche in Abhängigkeit wenigstens einer Information aus den personenbezogenen Daten gewählt ist. Außerdem ist die Struktur selbst und/oder eine Formgebung der Struktur des Sicherheitselements in Abhängigkeit von wenigstens einem weiteren Parameter gewählt.The value or security product according to the invention, in particular the identity card, has in particular a multi-layer structure which has at least one printed layer with personal data in the form of text elements and/or graphic elements and/or laser markings and at least one micro- or nanostructured security element with a structure includes, which is selected depending on at least one piece of information from the personal data. In addition, the structure itself and/or a shape of the structure of the security element is selected as a function of at least one further parameter.
Aufgrund der gewählten, aus zwei unterschiedlichen Parametern gebildeten, Struktur wird die Widerstandsfähigkeit des Wert- oder Sicherheitsprodukts, insbesondere dessen Oberfläche, verbessert, da sich durch die Verknüpfung einer ersten Grundstruktur und einer weiteren personalisierten und/oder nicht personalisierten Grundstruktur, Flächen hoher Strukturelementdichte begrenzen lassen. Ferner ist eine Verbesserung der Wahrnehmbarkeit und der Inspizierbarkeit des durch die Mikro- oder Nanostruktur gebildeten Sicherheitselements gegeben.Due to the selected structure, formed from two different parameters, the resilience of the value or security product, in particular its surface, is improved, since the linking of a first basic structure and a further personalized and/or non-personalized basic structure can limit areas with a high density of structural elements . Furthermore, there is an improvement in the perceptibility and inspectability of the security element formed by the microstructure or nanostructure.
Vorzugsweise liegt das Wert- oder Sicherheitsprodukt in ID 1-, ID 2-, ID 3- oder in irgendeinem anderen Format vor, beispielsweise in Heftform, wie bei einem passähnlichen Gegenstand. Das Wert- oder Sicherheitsprodukt ist im Allgemeinen ein Laminat aus mehreren Dokumentenlagen, die passgenau unter Wärmeeinwirkung und unter erhöhtem Druck flächig miteinander verbunden sind. Diese Produkte sollen den normierten Anforderungen genügen, beispielsweise ISO 10373, ISO/IEC 7810, ISO 14443.Preferably, the value or security product is in ID 1, ID 2, ID 3 or any other format, for example in booklet form, like a passport-like item. The value or security product is generally a laminate of several document layers, which are connected to one another with a precise fit under the action of heat and increased pressure. These products should meet the standardized requirements, for example ISO 10373, ISO/IEC 7810, ISO 14443.
Vorzugsweise bestehen die Produktlagen aus einem Trägermaterial, das sich für eine Lamination eignet. Das Wert- oder Sicherheitsprodukt kann aber vorzugsweise aus einem Polymer gebildet sein, das ausgewählt ist aus einer Gruppe, umfassend Polycarbonat (PC), insbesondere Bisphenol A-Polycarbonat oder ein Polycarbonat, gebildet mit einem geminal disubstituierten Bis-(hydroxyphenyl)-cycloalkan, Polyethylenterephthalat (PET), deren Derivate, wie Glykol-modifiziertes PET (PETG), Polyethylennaphthalat (PEN), Polyvinylchlorid (PVC), Polyvinylbutyral (PVB), Polymethylmethacrylat (PMMA), Polyimid (PI), Polyvinylalkohol (PVA), Polystyrol (PS), Polyvinylphenol (PVP), Polypropylen (PP), Polyethylen (PE), thermoplastische Elastomere (TPE), insbesondere thermoplastisches Polyurethan (TPU), Acrylnitril-Butadien-Styrol-Copolymer (ABS) sowie deren Derivate, und/oder Papier und/oder Pappe und/oder Glas und/oder Metall und/oder Keramik.The product layers preferably consist of a carrier material that is suitable for lamination. However, the product of value or security can preferably be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminally disubstituted bis(hydroxyphenyl)cycloalkane, polyethylene terephthalate (PET), their derivatives such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS) , polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and derivatives thereof, and/or paper and/or cardboard and/or glass and/or metal and/or ceramic.
Außerdem kann das Wert- oder Sicherheitsprodukt auch aus mehreren dieser Materialien hergestellt sein. Bevorzugt besteht es aus PC, PVC und PET. Die Polymere können entweder gefüllt oder ungefüllt vorliegen. Im letzteren Falle sind sie vorzugsweise transparent oder transluzent. Falls die Polymere gefüllt sind, sind sie opak. Die vorstehenden Angaben beziehen sich sowohl auf miteinander zu verbindende Folien als auch auf Flüssigformulierungen, die auf ein Vorprodukt aufgebracht werden, wie einen Schutz- oder Decklack. Bevorzugt wird das Wert- oder Sicherheitsprodukt aus drei bis zwölf, vorzugsweise vier bis zehn Folien, hergestellt. Die Folien können ferner Druckschichten tragen. Ein solcherart gebildetes Laminat kann abschließend ein- oder beidseitig mit dem Schutz- oder Decklack oder mit einer Folie überzogen werden. Die Folie kann insbesondere ein Volumenhologramm, eine Folie mit einem Oberflächenhologramm (beispielsweise einem kinegraphischen Element) oder eine Kratzschutzfolie sein. Derart gebildete Overlaylagen schützen ein darunter angeordnetes Sicherheitsmerkmal und/oder verleihen dem Dokument die erforderliche Abriebfestigkeit.In addition, the valuable or security product can also be made from several of these materials. It preferably consists of PC, PVC and PET. The polymers can be either filled or unfilled. In the latter case, they are preferably transparent or translucent. If the polymers are filled, they are opaque. The above information relates both to films to be bonded together and to liquid formulations that are applied to a preliminary product, such as a protective coating or top coat. The valuable or security product is preferably produced from three to twelve, preferably four to ten, films. The films can also carry printed layers. A laminate formed in this way can finally be coated on one or both sides with the protective or top coat or with a film. The foil can in particular be a volume hologram, a foil with a surface hologram (for example a kinegraphic element) or a scratch protection foil. Overlay layers formed in this way protect a security feature arranged underneath and/or give the document the required abrasion resistance.
Es ist die vorteilhafte Möglichkeit gegeben, dass das Sicherheitselement flächenartig mit einer hohen Strukturelementdichte von mehr als 500 DPI ("dots per inch"), vorzugsweise von mindestens 900 DPI bis 1200 DPI gebildet ist. Die Struktur liegt dabei insbesondere als eine Schraffur vor, die sehr präzise ausgestaltet ist. Damit lassen sich quasi Flächen bilden, die eine sehr hohe Strukturelementdichte besitzen, die aber durch die Überlagerung mit der Information aus dem wenigstens einen weiteren Parameter scharf begrenzt werden können.There is the advantageous possibility that the security element is formed areally with a high density of structural elements of more than 500 DPI ("dots per inch"), preferably of at least 900 DPI to 1200 DPI. In this case, the structure is present in particular as hatching, which is configured very precisely. In this way, surfaces can be formed which have a very high density of structural elements, but which can be sharply delimited by superimposing the information from the at least one further parameter.
Diese Begrenzung kann beispielsweise dadurch hervorgerufen werden, dass die Struktur des Sicherheitselements ermittelt ist aus der logischen Verknüpfung der personenbezogenen Daten und dem wenigstens einen weiteren Parameter.This limitation can be caused, for example, by the structure of the security element being determined from the logical combination of the personal data and the at least one further parameter.
Vorteilhafterweise wird ein Großteil der Dokumentenoberfläche mit der Struktur des Sicherheitselements versehen. Dies lässt sich beispielsweise durch eine sinusartige oder sinuswellenförmige, insbesondere flächenartige Gestaltung in Form einer Schwebung als Ergebnis eines Algorithmus, insbesondere eines Algorithmus mit wenigstens zwei Parametern erreichen.A large part of the document surface is advantageously provided with the structure of the security element. This can be done, for example, by a sinusoidal or sine wave-shaped, in particular planar design in the form of a Beat as a result of an algorithm, in particular an algorithm with at least two parameters.
Die Fälschungssicherheit wird zusätzlich dadurch erhöht, wenn nicht nur personenbezogene Textelemente zur Absicherung des Wert- oder Sicherheitsdokuments mit dem Strukturelement herangezogen werden, sondern wenn in die Struktur wenigstens eine Information aus einem Grafikelement ist, das beispielsweise dem Portraitbild des Inhabers des Wert- oder Sicherheitsprodukts entstammt. Vorzugsweise kann auch das vollständige Gesichtsbild, alternativ auch nur die Form des Kopfes, als Grundlage für die Bildung der Struktur des Sicherheitselements herangezogen werden.The security against counterfeiting is additionally increased if not only personal text elements are used to protect the value or security document with the structural element, but if the structure contains at least one piece of information from a graphic element, which comes from the portrait of the owner of the valuable or security product, for example . Preferably, the complete facial image, alternatively just the shape of the head, can also be used as the basis for forming the structure of the security element.
Eine verbesserte Absicherung gegen Fälschungen des Wert- oder Sicherheitsprodukts lässt sich außerdem dadurch erreichen, dass der in die Struktur einfließende weitere Parameter durch eine weitere personenbezogene Information aus der wenigstens einen Druckschicht und/oder Lasermarkierungen gebildet ist. Somit liegt bei der Festlegung der Struktur des Sicherheitselements also eine Überlagerung von wenigstens zwei personenbezogenen Informationen des Inhabers vor, die ein Fälschen des Wert- oder Sicherheitsprodukts noch schwieriger macht.Improved protection against counterfeiting of the value or security product can also be achieved in that the additional parameter flowing into the structure is formed by additional personal information from the at least one printed layer and/or laser markings. Thus, when determining the structure of the security element, there is a superimposition of at least two pieces of personal information about the owner, which makes counterfeiting of the value or security product even more difficult.
Vorteilhafterweise wird das Sicherheitselement derart in eine Decklage eingebracht, dass die strukturierten Flächen bei Betrachtung von reflektiertem Licht vor allem bei Reflektion im Glanzwinkel gegenüber den strukturfreien Bereichen stark kontrastieren und somit die eingebrachten Strukturen gut erkennbar sind.Advantageously, the security element is introduced into a cover layer in such a way that the structured areas contrast strongly with the structure-free areas when viewing reflected light, especially when reflected at the glancing angle, and the structures introduced are thus clearly recognizable.
Zudem ist die vorteilhafte Möglichkeit gegeben, dass das Sicherheitselement derart in eine Decklage einbracht ist, dass die strukturierten Flächen bei Betrachtung von transmittiertem Licht gegenüber den strukturfreien Bereichen stark kontrastieren und somit die eingebrachten Strukturen gut erkennbar sind. Hierdurch werden die Sichtbarkeit und Verifizierbarkeit des Sicherheitsmerkmals verbessert.In addition, there is the advantageous possibility that the security element is introduced into a cover layer in such a way that the structured areas contrast strongly with the structure-free areas when viewing transmitted light and the structures introduced are thus clearly recognizable. This improves the visibility and verifiability of the security feature.
Das Wert- oder Sicherheitsdokument kann auch eine Reihe aus mehreren mikro- oder nanostrukturierten Sicherheitselementen aufweisen. Somit wird also die Struktur oder ein Anteil der Struktur des Sicherheitselements fortgesetzt, wodurch eine erhöhte Sichtbarkeit und eine größere Abdeckung bzw. Absicherung der Dokumentenoberfläche erreicht werden kann.The value or security document can also have a number of micro- or nanostructured security elements. The structure or part of the structure of the security element is thus continued, as a result of which increased visibility and greater coverage or protection of the document surface can be achieved.
Die in Verbindung mit dem erfindungsgemäßen Wert- oder Sicherheitsprodukt erwähnten Vorteile, vorteilhaften Gestaltungen und Wirkungen gelten in gleichem Maße für das erfindungsgemäße Verfahren zur Herstellung eines solchen Wert- oder Sicherheitsprodukts. Es umfasst insbesondere die folgenden Schritte:
- A) Bereitstellen eines Trägermaterials,
- B) Anbringen einer oder mehrerer Druckschichten und Ausbildung von personenbezogen Daten in Form von Textelementen und/oder Grafikelementen auf das Trägermaterial,
- C) Formen oder Berechnen eines mikro- oder nanostrukturierten Sicherheitselements mit einer Struktur, die in Abhängigkeit wenigstens einer Information aus den personenbezogenen Daten sowie in Abhängigkeit von wenigstens einem weiteren Parameter gewählt ist,
- D) Anbringen, Aufbringen oder Einbringen des Sicherheitselements an, auf oder in eine der Druckschichten oder eine die Druckschichten bedeckenden Decklage.
- A) providing a carrier material,
- B) applying one or more layers of print and forming personal data in the form of text elements and/or graphic elements on the carrier material,
- C) forming or calculating a micro- or nanostructured security element with a structure that is selected depending on at least one piece of information from the personal data and depending on at least one other parameter,
- D) Attaching, applying or introducing the security element to, on or in one of the printed layers or a top layer covering the printed layers.
Auch beim erfindungsgemäßen Verfahren werden folglich personalisierte Daten mit Daten einer weiteren Struktur derart verknüpft, dass das resultierende durch Mikro- oder Nanostrukturierung erzeugte Sicherheitselement die Widerstandsfähigkeit der betroffenen Dokumentenoberfläche erhält und die Sichtbarkeit und Verifizierbarkeit des Sicherheitselements bzw. des Sicherheitsmerkmals verbessert wird.In the method according to the invention, too, personalized data is linked to data from another structure in such a way that the resulting security element produced by micro- or nanostructuring retains the resilience of the document surface concerned and the visibility and verifiability of the security element or security feature is improved.
Hierbei wird das Sicherheitselement vorzugsweise flächenartig mit einer hohen Strukturelementdichte von mehr als 500 DPI ("dots per inch") gebildet, wobei vorzugsweise die Struktur des Sicherheitselements ermittelt wird aus einer logischen Verknüpfung der personenbezogenen Daten und dem wenigstens einen weiteren Parameter. Hierzu ist vorzugsweise vorgesehen, dass die personenbezogenen Daten und der wenigstens eine weitere Parameter einen Algorithmus durchlaufen, durch den beispielsweise eine Schwebung aus den personenbezogenen Daten und dem wenigstens einen weiteren Parameter gebildet wird, die der Struktur des Sicherheitselements zugrunde gelegt wird. Die hierbei entstehende "Einhüllende" bildet damit eine "scharfe" Grenze zwischen einem strukturierten Bereich und einem unstrukturierten Bereich aus. Die Struktur liegt vorzugsweise aber als eine Schraffur vor, die sehr präzise ausgestaltet ist und damit eine größere Fläche abdeckt.The security element is preferably formed areally with a high structure element density of more than 500 DPI ("dots per inch"), with the structure of the security element preferably being determined from a logical combination of the personal data and the at least one other parameters. For this purpose, it is preferably provided that the personal data and the at least one further parameter run through an algorithm, by which, for example, a beat is formed from the personal data and the at least one further parameter on which the structure of the security element is based. The resulting "envelope" thus forms a "sharp" boundary between a structured area and an unstructured area. However, the structure is preferably in the form of hatching, which is designed very precisely and thus covers a larger area.
Eine verbesserte Absicherung lässt sich erzielen, wenn die in die Struktur einfließende Information ein Grafikelement in Form eines Portraitbilds, insbesondere eines Portraitbilds des Besitzers, ist. Die Fälschungssicherheit wird außerdem dadurch erhöht, dass der in die Struktur einfließende weitere Parameter durch eine weitere personenbezogene Information aus der wenigstens einen Druckschicht und/oder Lasermarkierungen gebildet ist, wozu beispielsweise personenbezogene Daten eines Textelements genutzt werden können. Für den weiteren Parameter können also personenbezogene Textelemente, wie bspw. das Geburtsdatum, der Name, der Wohnort oder dergleichen herangezogen werden.Improved security can be achieved if the information flowing into the structure is a graphic element in the form of a portrait image, in particular a portrait image of the owner. Protection against forgery is also increased by the fact that the additional parameter flowing into the structure is formed by additional personal information from the at least one printed layer and/or laser markings, for which personal data of a text element can be used, for example. Personal text elements such as the date of birth, the name, the place of residence or the like can therefore be used for the further parameter.
Zur Verbesserung der Verifizierung des Wert- oder Sicherheitsprodukts ist es sinnvoll, wenn das Sicherheitselement in eine Decklage einbracht wird, wodurch die strukturierten Flächen bei Betrachtung von reflektiertem Licht, insbesondere bei Reflektion im Glanzwinkel, gegenüber den strukturfreien Bereichen eine stärkere Kontrastierung aufweisen und somit die eingebrachten Strukturen gut erkennbar sind. Zudem ist die vorteilhafte Möglichkeit gegeben, dass die strukturierten Flächen bei Betrachtung von transmittiertem Licht gegenüber den strukturfreien Bereichen eine stärkere Kontrastierung aufweisen und somit die eingebrachten Strukturen gut erkennbar sind. Durch die logische Verknüpfung der personalisierten Daten und dem weiteren Parameter entsteht auch eine "scharfe" Grenze zwischen strukturiertem und unstrukturiertem Bereich, wodurch eine vereinfachte Überprüfung des Sicherheitsmerkmals gegeben ist.In order to improve the verification of the value or security product, it makes sense if the security element is introduced into a cover layer, whereby the structured areas have a stronger contrast when viewing reflected light, especially when reflected in the glancing angle, compared to the unstructured areas and thus the introduced areas structures are clearly visible. In addition, there is the advantageous possibility that the structured areas have a stronger contrast when viewing transmitted light compared to the structure-free areas and the introduced structures are thus clearly recognizable. The logical linking of the personalized data and the further parameter also creates a "sharp" boundary between the structured and unstructured area, which means that the security feature can be checked more easily.
Um die Struktur herauszubilden, kann ein Laser Verwendung finden. Als Laser kommt beispielsweise ein frequenzvervielfachter Festkörperlaser in Betracht, wobei auch Excimerlaser und Faserlaser Einsatz finden können. Diese Laser zeichnen sich durch ihre positive Eigenschaft aus, in einem sehr breiten Bereich von möglichen Leistungen betrieben werden zu können, so dass deshalb ein gewünschter Energieeintrag in das bestrahlte Material vorgebbar oder frei wählbar ist. Durch einen gepulsten Modus der Laser können leistungsstarke aber kurzzeitige Energiepulse in das Material eingebracht werden, so dass dieses abgetragen wird ohne zu verbrennen und ohne Schmauchspuren zu hinterlassen. Für den Eintrag leistungsstarker Laserpulse mit einem geringen Wärmeeintrag in das Material ist besonders der Einsatz eines Pikosekundenlasers oder eines Femtosekundenlasers bevorzugt.A laser can be used to form the structure. A frequency-multiplied solid-state laser, for example, can be used as a laser, although excimer lasers and fiber lasers can also be used. These lasers are characterized by their positive property of being able to be operated in a very wide range of possible outputs, so that a desired energy input into the irradiated material can be specified or freely selected. With a pulsed mode of the laser, powerful but short-term energy pulses can be introduced into the material so that it is removed without burning and without leaving traces of smoke. The use of a picosecond laser or a femtosecond laser is particularly preferred for the introduction of powerful laser pulses with a low heat input into the material.
