Definitions
- Identification document system arrangement and method for producing an identification document
- the invention relates to an identification document and a system arrangement and a method for protecting a personalized identification document from subsequent manipulation attacks.
- Identification documents are an important part of modern societies, enabling people to be identified and/or granting specific permissions to their owners.
- an identification document can be a card or a data carrier and designed as a passport, an identity card, a driver's license, a bank card such as a credit card or cash card, a label and/or an access pass. Due to their great importance for everyday life, for example for business interactions and access restrictions, the counterfeit security of identification documents is particularly important.
- identification documents can have one or more security features, by means of which the authenticity of the identification document can be checked and which make the forgery and/or manipulation of identification documents more difficult.
- an identification document can be personalized, for example, with an image applied to the surface or incorporated or embedded deep into the identification document.
- EP 0537484 A1 discloses an identification document in the form of a data carrier for colored or colored image information.
- the identification document consists of a card insert acting as a light-scattering background and a transparent film arranged thereon, on which an ink-receptive layer is arranged.
- the transparent film serves as a substrate into which optically recognizable information can be written for personalization by blackening the film material using fiber radiation.
- the color-receiving layer can be printed in color by applying or incorporating dyes or color pigments for personalization. In the following, color pigments are always meant when talking about dyes.
- the image information of an image to be recorded is first broken down into a light/dark component and at least one color value extract as the colored component.
- the light/dark portion is written into the transparent film using a fiber jet pen, resulting in more or less blackened areas of a gray tone image.
- the color value extract(s) of the image information is then superimposed on the gray tone image as a color image by applying or introducing appropriate dyes onto or into the color-receptive layer.
- an identification document is not falsified as a whole, but that an existing, real identification document is falsified in such a way that only individual data on the identification document, such as e.g. B. an image brought onto the document, for example of the owner, can be manipulated.
- a form of attack known as a face morphing attack aims to present a facial reference image that is automatically and successfully matched to more than one person by human experts. Such an attack can pose a critical security vulnerability when an identification document has an image manipulated by morphing.
- Such a forged (“morphed") identification document may allow more than one unique person to verify their identity with the one associated with the identification document.
- Such false association of subjects with the document identity may enable a variety of illegal activities , such as financial transactions, illegal immigration, human trafficking and circumventing legal black identity lists.
- the above face morphing attack is carried out on an identification document that has already been linked to the document identity by a photo of the document holder, ie has been personalized.
- image information could be added to the existing photo in such a way that the identification document presents a facial reference image that is automatically and successfully compared with another person by human experts.
- additional light/dark information could be inscribed into the transparent film by means of a laser beam writer in order to manipulate the gray tone image according to the principles of the face morphing attack.
- color information could be added to the color image on the identification document, which is superimposed on the gray tone image, by adding appropriate dyes to or in the color-receiving layer, so that the colored image information is also manipulated using the principles of a face-morphing attack. It is an object of the present invention to create a manipulation-proof identification document and a method for protecting a personalized identification document from subsequent manipulation, in particular a face-morphing attack. In particular, progress in the manipulation of identification documents can be countered by improving the protection against manipulation compared to already known identification documents.
- the personalized image data of the identification document could be protected against subsequent falsification (for example through morphing) or if such an attack could at least be made more difficult.
- an identification document has a carrier element with a surface that has a personalization area.
- a first personalization layer is integrated or embedded in the carrier element at a depth below the surface in the personalization area.
- a second layer of personalization is on and/or in the surface in the personalization area.
- a laser-sensitive additive is contained in the second personalization layer or in a protective layer arranged over the second personalization layer.
- the protective layer can be omitted or, alternatively, still be present, in which case the protective layer can then contain the laser additive, but need not contain it.
- Below the surface at a depth can in principle mean that the first personalization layer is located directly below the surface and thus below the second personalization layer, the depth then being essentially zero.
- “below the surface at a depth” means that the first personalization layer is integrated or embedded in the interior of the carrier element at a distance from the surface and thus at a distance from the second personalization layer.
- On the surface means that the second personalization layer can in principle be arranged on the surface, so that the surface is the boundary layer between the carrier element and the second personalization layer.
- “On the surface” means that the material and/or the surface of the carrier element and/or the material of the second personalization layer can be designed in such a way that components of the second personalization layer can penetrate from the surface into the depth of the carrier element or the second personalization layer can penetrate over an area from the surface into the carrier element, for example due to a structuring of the surface, first can ck. It is of course also possible for the second personalization layer to be designed in such a way that it is located both on and in the surface.
- the first personalization layer can preferably present an achromatic color component or black component and the second personalization layer can present a colored component of an image or a logo.
- the first personalization layer and the second personalization layer can be aligned with one another in an overlapping, register-accurate manner in the direction of a normal to the surface of the carrier element. This has the advantage that when viewed from above, i.e. in the direction normal to the surface of the carrier element, they form a color image for a human observer with particularly pronounced black components because the black component is contributed as a real grayscale image or black image by the first personalization layer .
- the first personalization layer and the second personalization layer together present a colored image or photo of the face of the owner of the identification document to which the document identity is linked.
- the first personalization layer is preferably a laser engraving embedded in or integrated into the carrier element.
- Laser engraving is to be understood here as “marking by means of a laser", ie there does not have to be any material removal. Rather, the first personalization layer can preferably be formed by at least partially carbonizing the material of the carrier element.
- the first personalization layer presents the black portion of an image or a logo and is formed by an integrated laser engraving in the material of the carrier element. In this case, the black component is integrated in particular in the interior of the carrier element in such a way that the surface of the carrier element is mechanically unimpaired.
- the laser engraving integrated in the carrier element in this way can be produced in particular by adding a laser, for example particles that are designed to absorb energy from a laser beam, into a material of the carrier element at least at the location or in the area during manufacture of the carrier element the first layer of personalization.
- the laser additive can be formed, for example, as soot particles and/or nanoscalar metal oxide particles.
- the integrated laser engraving is preferably introduced into the carrier element by a laser.
- the integrated engraving can be an engraving according to the so-called LPI principle (laser protected image).
- LPI engraving is particularly precise and very durable. This is advantageous because LPI engraving makes at least the contour or the black parts of a color image more stable over the long term, since in this way the black part of the personalization information is shifted to the interior of the carrier element and is therefore better protected from environmental influences.
- the material of the carrier element is preferably at least light, for example white, or transparent in the area of the first personalization layer and in the non-engraved, ie non-personalized, state. Likewise the material of the carrier element in the area between the first personalization layer and the second personalization layer is transparent at least for visible light.
- the laser-sensitive particles of the laser additive that are integrated into the material of the carrier element, in particular dispersed therein, can be heated with a laser. At least part of the thermal energy absorbed in the process is given off by the particles of the laser additive to the surrounding material of the carrier element.
- the material of the carrier element is preferably selected, at least in this area, so that it changes its color as a result of the heating, and thus becomes darker, in particular black, in order to be able to present the black portion of the image or logo.
- the material of the carrier element carbonizes in the area of heating during the integrated laser engraving and consequently assumes a darker, in particular black, color there.
- the first personalization layer in the form of the integrated engraved black portion is advantageous because it is particularly resistant to aging, weathering and abrasion.
- the integrated engraving enables a particularly precise and consistent design of the black component. An integrated engraving of the carrier element is difficult to produce in a sufficient quality, ie not recognizable as fake, in particular for a manual forgery.
- the second personalization layer is preferably a color layer with colorful color particles made of color pigments or dyes.
- the second personalization layer can also contain black particles. It is preferably provided that the second personalization layer consists only of colored paint particles. "Only from colorful color parts no" means in particular that the second personalization layer does not contain any black particles.
- a laser additive can be integrated or dispersed in the color particles manipulation protection can be integrated into the identification document before the second personalization layer is applied, which protects the identification document against subsequent addition of black components by means of laser engraving in the first personalization layer This laser engraving of the second layer of personalization can be seen by the naked human eye or even be felt haptically on the surface.
- a protective layer in which a laser additive is also integrated, can be arranged over the second personalization layer in line with the important idea mentioned above.
- the same or even additional protection against manipulation, as explained above in connection with the second personalization layer, can be achieved with the protective layer.
- the protective layer can be applied over the entire surface of the carrier element; this is advantageous since the protective layer can be attached to the carrier element as a closed surface in one step.
- the protective layer can be applied partially on the surface, but at least over the entire area over the personalization area, ie the second personalization layer; this is beneficial when applying the protective layer is to be applied at the same time as or immediately after the second personalization layer is produced line by line, possibly also line by line or in sections, with the same device with which the second personalization layer is produced. Since it is also possible to partially add the laser additive to the protective layer when applying the protective layer or to switch between a material for the protective layer with a laser additive and without a laser additive accordingly.
- the protective layer over the second personalization layer, it being possible for a symbol, a text or a regular structure to be formed by means of the partial application; this is advantageous because it can be used to generate optical changes as a result of a manipulation attack with a laser that are easier to recognize with the naked eye. It is particularly advantageous that a desired structure, which should be recognizable by a subsequent attempt at manipulation by means of a laser due to the resulting blackening, can be preset by partially applying the protective layer with an integrated laser additive or, as it were, by partially integrating the laser additive into the protective layer .
- the second personalization layer and optionally the protective layer are preferably printed layers.
- the second personalization layer and/or possibly the protective layer can be done by digital printing, with dye transfer by means of D2T2 printing, thermal transfer printing, inkjet printing or liquid ink printing and/or retransfer printing to the surface of the carrier element takes place.
- the protective layer can be arranged over the second personalization layer in the form of a lollipop or as a lacquer layer.
- the sensitization to laser beams in the carrier element is set to be weaker in the area of the first personalization layer than possibly in the second personalization layer and/or the possibly protective layer.
- the identification document can be formed as a card or a data carrier.
- the identification document can be in the form of a passport, an identity card, a driver's license, a bank card, for example a credit card or cash card, a label and/or an access pass.
- the identification document can also form only part of a larger unit, for example part of a passport.
- the identification document can also have multiple surfaces, for example a front and a back. It is possible for a surface to have one or more personalization areas according to the principles explained above.
- the personalization areas in a surface can, for example, directly adjoin one another or be spaced apart from one another.
- the personalization area is preferably limited to a partial area of one of the surfaces, in particular the partial area in which the first personalization layer is located. In principle, however, the personalization area can also extend to the entire surface.
- the surface of the carrier element in the personalization area can have a structure.
- the surface of the carrier element in the personalization area can be formed with a multiplicity of structural elements which are aligned uniformly with respect to one another and are raised in relation to the surface.
- the structural elements of the multiplicity of structural elements can be formed directly adjacent to one another.
- the structural elements can have a center distance between vertical axes, which are normal to the surface, of the respective structural elements of less than 250 ⁇ m.
- At least one structural element of the plurality of structural elements can at least partially have an arcuate contour in cross section perpendicular to the surface; the arcuate contour can be formed with a radius of at most 125 gm.
- At least one structural element of the plurality of structural elements can be dome-shaped on the side facing away from the carrier element.
- At least one structural element of the plurality of structural elements can be designed as a spherical segment, with the cut surface of the spherical segment facing the carrier element.
- At least one structural element of the multiplicity of structural elements can be designed as a semicircular bar.
- the structural elements of the multiplicity of structural elements can each have a height of 10 ⁇ m to 60 ⁇ m.
- the structural elements of the multiplicity of structural elements can be aligned with one another as a uniform grid.
- the second personalization layer in the personalization area with the multiplicity of structural elements can be designed at least partially as a tilting image.
- the achromatic portion or black portion of the tilting image is integrated into the carrier element by means of the first personalization layer.
- the flip image be designed as MLI (multiple laser image) or CLI (changeable laser image).
- a system arrangement for personalizing a non-personalized identification document has: a first device for providing a carrier element with a surface which has a personalization area; a second device, in particular a laser beam writer, for producing a first personalization layer at a depth below the surface in the carrier element in the personalization area by means of laser engraving; a third device, in particular a printing device, for producing a second personalization layer on and/or in the surface of the carrier element in the personalization area.
- the system arrangement provides that the device for generating the second personalization layer is set up to integrate a laser-sensitive additive (laser additive) into the second personalization layer, and/or is set up after or in parallel with the generation of the second personalization layer, to apply a protective layer containing the laser additive over the second personalization layer.
- a laser-sensitive additive laser additive
- a method for personalizing a non-personalized identification document is proposed, which is designed analogously to the system arrangement.
- the method has the following steps: a step A with providing a carrier element with a surface which has a personalization area; a step B with production of a first personalization layer at a depth below the surface in the carrier element in the personalization area by means of laser engraving; a step C with production of a second personalization layer on and/or in the surface of the carrier element Personalization panel.
- step C additionally has a step CI with integrating a laser-sensitive additive (laser additive) into the second personalization layer, and/or a step C2 with arranging over the second personalization layer Protective layer containing the Laseraddi tive.
- laser additive laser additive
- the carrier element is preferably made of a plastic.
- the support element can be single-layer or multi-layer, for example made of PVC (polyvinyl chloride) and/or PET (polyethylene terephthalate) and/or ABS (acrylonitrile butadiene styrene) and/or polycarbonate.
- the structural elements, if any, are preferably formed from polycarbonate. This is advantageous because polycarbonate allows the structural elements to be made particularly hard and resistant to mechanical stress.
- the multiplicity of structural elements can already be formed on the carrier element during production of the carrier element, for example by injection molding or by welding under high pressure at the appropriate temperature to form a homogeneous inseparable plastic unit, ie in particular by hot pressing or lamination.
- the identification document can be protected more effectively against falsification by providing the protection proposed here against subsequent laser engraving, for example for a face morphing attack.
- a known identification document could possibly be subsequently falsified by manipulating the first personalization layer of an identification document already personalized with image information by adding additional black components to the first personalization layer by means of laser engraving for a face morphing attack.
- subsequent laser engraving of the first personalization layer results in the second personalization layer and/or the protective layer arranged on the second personalization layer likewise as a result of the energy input by means of a laser, is optically recognizable with the naked human eye and/or is engraved on the surface of the personalization area so that it can be felt or touched.
- Such a subsequent falsification can then be recognized more easily than if a known identification document is subsequently engraved with a laser only in the first personalization layer.

- FIG. 1 shows a perspective view of an exemplary embodiment of an identification document 10 according to the invention.
- a section line A-A is plotted in FIG. 1, which defines the lateral sectional view for illustrating different versions of the identification document 10 in FIGS.
- the identification document 10 is in the form of a card, for example an ID card or a driver's license or a bank card or an access card, not to mention a few specific possible applications.
- the identification document 10 has a carrier element 20 .
- the Trä gerelement 20 is made of plastic, for example.
- the carrier element 20 can be constructed in one layer or in multiple layers. The materials can suitably be different, similar or identical.
- the carrier element 20 has a surface 30 which, according to the exemplary embodiment, is the front side 31 of the card.
- the carrier element 20 can also have a number of surfaces, for example a front side 31 and a rear side 33 .
- the surface 30 has a main level 35 and a personalization area PB.
- the main level 35 is according to the Embodiment defined by the surface 30, which is outside of the personalization area PB.
- the personalization area PB extends only partially over the surface 30.
- the personalization area PB can also extend completely over the entire surface 30.
- the personalization area PB of the exemplary embodiments explained here presents a color photo FF of the face of the owner of the identification document.
- FIG. 2 shows a perspective representation of the identification document 10 of FIG. 1, exploded in the direction of a spatial axis RA, to illustrate the personalization area PB, which has a first personalization layer PI and a second personalization layer P2.
- the personalization area PB of a personalized identification document 10 presents a color photograph FF, which shows a human face of an owner of the identity document 10;
- the personalization links the document identity to the owner's biometric features, so that the owner can be identified by comparison with the color photo FF in the personalization area PB if the comparison is positive.
- the first personalization layer PI preferably contains the achromatic portion, ie the black portion, of the color photograph FF and the second personalization layer P2 contains the colored portions or color extracts of the color photograph FF.
- the black component can also be contained in the second personalization layer P2.
- the black component is preferably introduced into the material of the carrier element 20 of the identification document 10 by means of integrated laser engraving LG (also known as LIP—laser image protection). and the colored portions are applied to the surface 30 of the identification document 10 in the personalization area PB, for example by means of inkjet printing technology or by laminating a transfer film.
- the second personalization layer P2 is preferably applied only with colorful color particles FP. Thus, the achromatic black portion remaining in comparison to the colored color particles FP is not applied to the surface 30, but integrated or embedded in the carrier element 20 by means of LIP.
- the first personalization layer PI produced in the carrier element 30 by means of LIP is located at a depth T in relation to the surface 30, in particular the front side 31, of the carrier element 20 and is therefore at a distance from the second personalization layer P2 and also from the surface 30.
- the material of the carrier element is transparent in the area between the first and the second personalization layer P1 and P2, at least for visible light.
- the first personalization layer PI is at a depth T relative to the surface 30 of the carrier element 20.
- a laser-sensitive additive (laser additive) LA is integrated or dispersed in the color particles used to form the second personalization layer P2.
- the second personalization layer P2 produced using a printing technology, in particular an inkjet printer technology, such as liquid ink printing with drop-on-demand (DoD), is sensitized to an energy input using a laser.
- a printing technology in particular an inkjet printer technology, such as liquid ink printing with drop-on-demand (DoD)
- the laser additive LA can, for example, contain soot particles or nanoscalar metal oxide particles which, with an appropriate setting of the particle density, do not impair the optical properties of the second personalization layer P2 for visible light, but absorb sufficient energy when irradiated with a laser that a corresponding Carbonization of the second personalization layer and possibly in the surface 30 of the adjoining carrier element 20 takes place.
- the result can be achieved in such a way that the attempt to subsequently add black parts to the first personalization layer PI by means of laser engraving LG with a laser results in a corresponding laser engraving LG in the second personalization layer P2. This makes such a manipulation attempt, for example for a face morphing attack, significantly more difficult, if not completely frustrated.
- the carrier element 20 is formed in the personalization area PB with a variety of number of structural elements SE in comparison to the embodiment of FIG.
- the structural elements SE of the plurality of structural elements SE referred to here for short as structural elements SE, are raised in FIG. 4 with respect to the main plane 35. while they are formed in Fig. 5 compared to the main plane 35 from closing essentially. That is, in the exemplary embodiment in FIG. 4, the structural elements SE are located on the main plane 35 of the carrier element 20, while in the exemplary embodiment in FIG. 5 the structural elements SE are arranged on a plane that is opposite the main plane 35 of the carrier element 20 inside the carrier element 20 is located, so that the structural elements SE are not raised relative to the carrier element 20.
- the structural elements SE in the exemplary embodiments in FIGS. 4 and 5 are in particular designed in such a way that they are directed away from the carrier element 20 in relation to it, preferably in the direction of the spatial axis RA (FIG. 2).
- the structural elements SE according to the exemplary embodiments of FIGS. 4 and 5 are arranged uniformly and have at least partially an arcuate contour in the cross section perpendicular to the main plane 35 .
- An advantage of the identification document 10 of FIGS. 4 and 5 is that the structural elements SE allow for the second personalization layer P2 on the one hand standard inkjet inks with a less good bond to the surface 30, but also polycore inks with a very good bond to the substrate to use and at the same time to achieve a high stability of the second personalization layer P2 against mechanical and / or chemical influences.
- the long-term stability of the external second personalization layer P2 can be increased by the identification document 10 and the method for personalizing the identification document 10 with structural elements SE in the personalization area PB.
- the personalization area PB in FIGS. 4 and 5 is characterized in that the second personalization layer P2 is applied to or in the surface 30 of the carrier element 20 for a long time, i.e. preferably for at least a period of several months, in particular at least one year or even up to ten years.
- first the second personalization layer P2 is applied to the structural elements SE.
- the same protection against subsequent laser engraving of the first personalization layer PI can be achieved as in the exemplary embodiment in FIG.
- the second personalization layer P2 in the embodiment of Fig. 4 does not contain a laser additive LA, but only the additional protective layer S. It goes without saying, however, that it is fundamentally possible to use the laser additive LA both in the second personalization layer P2 and also in the protective layer S. This further exemplary embodiment is not shown in the figures.
- the second personalization layer P2 is first applied or pressed onto the structural elements SE that are recessed in the surface 30 of the carrier element 20 .
- a protective layer S in the form of a film F is then applied over the second personalization layer P2, which is doped with a laser additive LA or in the material of which the laser additive LA is dispersed.
- the protective layer S in the form of a film F is applied over the entire surface 30 of the carrier element 20 in the exemplary embodiment in FIG. 5 . This is advantageous if a uniform, closed surface for the document 10 is desired.
- a protective layer S can be provided over the entire area or partially limited to the personalization area PB, which in turn may or may not contain a laser additive LA.
- the protective layer S is basically applied as a film F (Fig. 5) or in the form of a lacquer layer LS (Fig. 3) using a printing technology suitable for this purpose, for example using an inkjet printing technique or liquid inks printing using drop-on-demand (DoD).
- a printing technology suitable for this purpose for example using an inkjet printing technique or liquid inks printing using drop-on-demand (DoD).
- DoD drop-on-demand
- the protective layer S in the form of a film F or as a lacquer layer LS can subsequently be applied to the second personalization layer P2 with the personalized image data, partially or over the entire surface, at least in the personalization area PB.
- the partial application can be structured, for example in the form of an image, a logo, a text or a regular pattern, with the protective layer S preferably being homogeneous Laser additive LA is integrated.
- the protrusion of a structured protective layer S is advantageous because subsequent laser engraving of the first personalization layer PI means that the structure of the protective layer S only then becomes clearly visible and the manipulation is therefore easier to recognize with the naked human eye . This is illustrated by way of example in FIG. 6 .
- FIG. 6 shows a perspective view of an exemplary embodiment of an identification document 10 according to the invention with an optically visible structure ST as a result of an attempt at manipulation by means of subsequent laser engraving of the first personalization layer PI.
- the protective layer S equipped with an integrated laser additive in the form of regular transverse stripes in the personalization area PB of the identity document 10 is in no way limiting in the exemplary embodiment in FIG. 6, for example by an inkjet printing technique.
- the protective layer S structured in this way has blackened due to an attempt at subsequent laser engraving of the first personalization layer PI and can be recognized as the optically recognizable structure ST.
- the color photo FF in the personalization area PB thus clearly shows the attempted manipulation by means of the optically recognizable structure ST in the form of the horizontal stripes shown as an example.
- the laser additive LA selectively when applying the color particles for the second personalization layer P2, so that structuring of the sensitization for laser beams in the second personalization layer P2 can also be achieved.
- the sensitization to laser beams in the material in the area of the first personalization layer PI can be set to be weaker than in the second personalization layer P2 and/or the protective layer S, if applicable.
- FIG. 7 shows a simplified schematic representation of a system arrangement for personalization and for protection against subsequent laser engraving of an information document according to the invention.
- the system arrangement 40 for personalizing an identification document 10 is basically equipped with the system components known, for example, in connection with the CLIP ID technology mentioned elsewhere.
- the system arrangement 40 has a first device VI, which is used to provide a non-personalized identification document 10 with the carrier element 20 with the surface 30 that has the personalization area PB for personalization.
- the system arrangement 40 has a second device V2, for example a laser beam writer.
- the second device V2 is set up to produce the first personalization layer PI at a depth T below the surface 30 in the carrier element 20 in the personalization area PB by means of laser engraving LG.
- the system arrangement 40 has a third device V3, for example an inkjet printing device Liquid ink printing by DoD, for generating the second personalization layer P2 on and/or in the surface 30 of the carrier element 20 in the personalization area PB.
- the third device V3 for generating the second personalization layer P2 is additionally set up to integrate a laser additive LA into the second personalization layer P2 and/or, after or parallel to the generation of the second personalization layer P2, to apply a protective layer S, which contains the laser additive, over the second personalization layer P2.
- the system arrangement 40 can be configured in accordance with the exemplary embodiment explained above to structure the presence of laser additive in the second personalization layer P2 and/or the protective layer S.
- the first personalization layer PI, the second personalization layer P2 and possibly the protective layer S can in principle be generated one after the other.
- the first personalization layer PI and the second personalization layer P2 can be generated in parallel, but with a time offset from sections or lines; This means that the second device V2 first engraves one of the several lines of the first personalization layer PI and then (i.e. with a time delay) the third device V3 applies the corresponding lines of the second personalization layer P2 over the lines of the first personalization layer PI that have already been generated, while the second device V2 is already generating another row or rows of the first personalization layer PI.
- Fig. 8 shows a schematic flowchart to illustrate the steps of a method for personalizing and protecting against subsequent laser engraving of an information document 10 according to the invention.
- the method for personalizing an identification document 10 has the following steps: a step A with providing a not yet personalized identification document 10 with a carrier element 20 with a surface 30 which has a personalization area PB; a step B with production of a first personalization layer PI at a depth T below the surface 30 in the carrier element 20 in the personalization area PB by means of laser engraving; a step C with production of a second personalization layer P2 on and/or in the surface 30 of the carrier element 20 in the personalization area PB.
- step C also has: a step CI with integration of a laser additive in the second personalization layer P2 and/or a step C2 with arranging over the second personalization layer P2 Protective layer S containing the laser additive.
