[0135] FIG. 1a and FIG. 1b show a document 1 with a carrier substrate 2 and a decorative ply 3 applied to the surface 4 of the carrier substrate 2.
[0136] The document 1 is in particular a security document such as a banknote, an identity document, a visa or a security.
[0137] The carrier substrate 2 is preferably a paper substrate, in particular a single-layered paper substrate. It is also possible for the carrier substrate 2 to comprise cotton fibers, wood fibers, pulp fibers, textile fibers and/or plastic fibers. The carrier substrate 2 preferably has a layer thickness between 30 m and 250 m, preferably between 50 m and 100 m. It is also possible for the carrier substrate 2 to have additives, in particular security fibers and/or security pigments and/or dyes and/or watermarks. The carrier substrate 2 shown in FIG. 1a and FIG. 1b is a single-layered paper substrate with a layer thickness of 80 m.
[0138] As shown in FIG. 1b, the decorative ply 3 is applied to the upper side 4 of the carrier substrate 2. It is possible for the decorative ply 3 to be formed single- or multi-layered. The decorative ply 3 preferably has one or more color layers, one or more layers with optically variable pigments, one or more thin-film layer systems, one or more layers generating an optically variable effect, one or more layers with color pigments and/or dissolved dyes and/or one or more layers with microstructures. The layers advantageously generate at least one color effect in the range of the wavelengths visible to the human eye, in particular in the wavelength range of from 400 nm to 800 nm, when the document 1 is viewed from the underside 5 of the carrier substrate 2. It is advantageous here if the microstructures are selected from the group Kinegram, holograms, blazed gratings, in particular asymmetrical sawtooth relief structures, diffraction structures, in particular linear sinusoidal diffraction gratings or crossed sinusoidal diffraction gratings or linear single- or multi-step rectangular gratings or crossed single- or multi-step rectangular gratings, mirror surfaces, matte structures, in particular anisotropic or isotropic matte structures, or combinations of these structures.
[0139] As in FIG. 1a and FIG. 1b, the carrier substrate 2 is perforated in the regions 10, represented in black here, with the result that the decorative ply 3 is visible in the regions 10 to an observer 9 of the document 1 from the underside 5 of the carrier substrate 2. Here the carrier substrate 2 is perforated by means of a laser.
[0140] The terms upper side 4 and/or underside 5 here serve in particular to distinguish between the surfaces of the carrier substrate 2 and in particular represent a frame of reference. However, it is also possible, instead of these terms of reference, to use the terms first side and second side.
[0141] By region is meant here in each case a defined surface area of a layer or ply which is occupied when viewed perpendicular to a plane spanned by the carrier substrate 2. Thus, for example, the carrier substrate 2 has the regions 10, wherein each of the regions 10 in each case occupies a defined surface area when viewed perpendicular to a plane spanned by the carrier substrate 2.
[0142] By perforation of a layer is meant here the complete removal of a layer, in particular by means of laser cutting and/or laser ablation. If, for example, a layer is perforated in a region 10, the corresponding layer has been completely removed in this region 10. The perforation here is preferably effected on the basis of laser cutting and/or laser ablation, with the result that the perforated layers are worn away and/or ablated and/or burnt up and/or evaporated residue-free in the corresponding regions 10. Thus, for example in FIG. 1a and FIG. 1b, the carrier substrate 2 is completely removed in the regions 10, in particular by means of laser cutting and/or laser ablation, with the result that the carrier substrate 2 is worn away residue-free in the regions 10.
[0143] By visible is meant here that the decorative layer 3 is recognizable for the observer 9 when the document 1 is viewed by the naked human eye from the underside 5 of the carrier substrate 2.
[0144] As indicated in FIG. 1a by the dashed lines, the decorative ply 3 is applied to the upper side 4 of the carrier substrate 2 only in regions. The example in FIG. 1a shows a strip form of the decorative ply 3, wherein alternatively or additionally other forms, for example a patch form, are also possible. The decorative ply 3 further completely covers the regions 10 when viewed perpendicular to a plane spanned by the carrier substrate 2. It is hereby ensured that the decorative ply 3 or the optical effects generated by the decorative ply are visible to the observer 9 in all perforated regions 10 from the underside 5 of the carrier substrate 2.
[0145] As shown in FIG. 1a, the regions 10 are designed linear. However, it is also possible for the regions 10 to be designed as a graphic motif, alphanumeric, punctiform and/or as machine-readable code. A pattern can be, for example, a graphically designed outline, a figurative representation, an image, a motif, a symbol, a logo, a portrait, an alphanumeric character, a text and the like.
[0146] FIG. 1c schematically shows an enlarged section 40 of FIG. 1a. As shown in FIG. 1c, the decorative ply 3 is recognizable in the regions 10 in which the carrier substrate 2 is perforated. The regions 10, as shown in FIG. 1c, further have the line width 50. The line width 50 is preferably at most 2 mm, preferably at most 1 mm, when viewed perpendicular to a plane spanned by the carrier substrate 2. However, it is expedient if the line width 50 of the regions 10 when viewed perpendicular to a plane spanned by the carrier substrate 2 is chosen to be at least so wide that the decorative ply 3 is visible to the naked human eye in the region 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. The line width 50 is therefore preferably at least 20 m, particularly at least 50 m, further preferably at least 100 m, in particular preferably at least 200 m. The line width shown in FIG. 1c is 200 m. The above indications of size with respect to the line width of the regions can, however, also relate to the width and/or the diameter of the regions 10 depending on the design of the regions 10. Thus, it is possible, if the regions are formed as circles, for these to have a diameter between a minimum of 20 m, preferably a minimum of 50 m, further preferably a minimum of 100 m, in particular preferably at least 200 m, and at most 2 mm, preferably at most 1 mm.
[0147] As shown in FIG. 1c, the optically perceptible effect for the observer 9 in the regions 10 is defined and/or predetermined by the decorative ply, as the carrier substrate 2 is perforated only in the regions 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. The decorative ply 3 is thus visible to the observer 9 only in these perforated regions 10. Through its design, the decorative ply 3 thus defines the optical effects visible to the observer 9 in the perforated regions 10 from the underside 5 of the carrier substrate 2.
[0148] FIG. 2a to FIG. 2c schematically show sectional representations of documents 1.
[0149] The document 1 shown in FIG. 2a comprises a carrier substrate 2 and a decorative ply 3 applied to the upper side 4 of the carrier substrate 2.
[0150] The carrier substrate 2 shown in FIG. 2a is formed as a multi-layered carrier substrate 2 and comprises the layers 6, 7. The carrier substrate 2 shown in FIG. 2a is a multi-layered hybrid substrate which has two paper plies 6 and a plastic ply 7. The plastic ply 7 is preferably a plastic ply made of polyamide. The carrier substrate 2 preferably has a layer thickness between 30 m and 250 m, preferably between 50 m and 100 m.
[0151] As shown in FIG. 2a, both the paper plies 6 and the plastic ply 7 are perforated in the regions 10, with the result that the carrier substrate is perforated completely in the regions 10 such that the decorative ply 3 is visible in the regions 10 when the document 1 is viewed from the underside 5 of the multi-layered carrier substrate 2. In particular as the paper plies 6 on the outside are matte and thus substantially lightproof, a complete perforation of the carrier substrate 2 is necessary in order to make the decorative ply 3 visible to an observer when the document 1 is viewed from the underside 5 of the multi-layered carrier substrate 2.
[0152] With respect to the design of the regions 10 as well as of the decorative ply 3, reference is made here to the above statements.
[0153] The document 1 shown in FIG. 2b comprises a carrier substrate 2 and a decorative ply 3 applied to the upper side 4 of the carrier substrate 2.
[0154] The carrier substrate 2 shown in FIG. 2b is formed as a multi-layered carrier substrate 2 and comprises the layers 6, 7. The carrier substrate 2 shown in FIG. 2b is a multi-layered carrier substrate 2 which has one paper ply 6 and two plastic plies 7. The plastic plies 7 here preferably comprise polyester and/or polyethylene terephthalate (=PET). It is further possible for at least one of the plastic plies 7 to be transparent. The plastic plies 7 shown in FIG. 2b are transparent plastic plies.
[0155] By transparent is meant here the property of materials to allow light from the wavelength range visible to the human eye through, in particular from the wavelength range between 380 nm and 780 nm.
[0156] As shown in FIG. 2b, the paper ply 6 and the plastic ply 7 arranged on the underside 5 of the carrier substrate 2 are perforated in the regions 10. As the plastic plies 7 are designed transparent, in particular as the plastic ply 7 not perforated in the region 10 and arranged on the upper side of the carrier substrate 2 is transparent, the decorative ply 3 is visible in the regions 10 when the document 1 is viewed from the underside 5 of the multi-layered carrier substrate 2. As shown in FIG. 2b, the carrier substrate 2 is therefore not completely perforated, wherein the decorative ply 3 is, however, still visible in the regions 10 when the document 1 is viewed from the underside 5 of the multi-layered carrier substrate 2.
[0157] With respect to the design of the regions 10 as well as of the decorative ply 3, reference is made here to the above statements.
[0158] The document 1 shown in FIG. 2c comprises a carrier substrate 2 and a decorative ply 3 applied to the upper side 4 of the carrier substrate 2.
[0159] The carrier substrate 2 shown in FIG. 2c is formed as a multi-layered carrier substrate 2 and comprises the layers 7, 8. The carrier substrate 2 shown in FIG. 2c is a multi-layered carrier substrate 2 which has a transparent plastic ply 7 and an opaque layer 8. The opaque layer 8 is preferably an opacified varnish layer and/or a printed color layer. The transparent plastic ply 7 is preferably a polymer layer.
[0160] As shown in FIG. 2c, the opaque layer 8 is perforated in the regions 10. As the plastic ply 7 is designed transparent, the decorative ply 3 is visible in the regions 10 when the document 1 is viewed from the underside 5 of the multi-layered carrier substrate 2. As shown in FIG. 2c, the carrier substrate 2 is therefore not completely perforated, wherein the decorative ply 3 is, however, still visible in the regions 10 when the document 1 is viewed from the underside of the multi-layered carrier substrate 2. As shown in FIG. 2c, at least the layer 8 of the carrier substrate 2 is perforated in the regions 10. A perforation of the transparent plastic ply 7 is therefore not necessary in order to be able still to recognize the decorative ply 3 in the regions 10 when the document 1 is viewed from the underside 5 of the multi-layered carrier substrate 2.
[0161] With respect to the design of the regions 10 as well as of the decorative ply 3, reference is made here to the above statements.
[0162] FIG. 3a to FIG. 3f schematically show further embodiment variants of documents 1 in top view from the underside of the carrier substrate 2, which in each case comprise a carrier substrate 2, as well as a decorative ply applied to the upper side of the carrier substrate 2.
[0163] As indicated in FIG. 3a to FIG. 3f by the dashed lines, the decorative ply is applied to the upper side of the carrier substrate 2 only in regions, wherein the decorative ply completely covers the regions 10, 11 and/or 12 when viewed perpendicular to a plane spanned by the carrier substrate 2. With respect to the further design of the decorative ply, reference is made here to the above statements. With respect to the design of the carrier substrate 2, reference is likewise made here to the above statements.
[0164] As shown in FIG. 3a, the carrier substrate 2 is perforated in the regions 10 such that the decorative ply is visible in the regions 10 of the document 1 from the underside of the carrier substrate 2.
[0165] As shown in FIG. 3a, the regions 10 here are preferably designed linear. Each of the regions 10 further represents a pattern. A pattern can be, for example, a graphically designed outline, a figurative representation, an image, a motif, a symbol, a logo, a portrait, an alphanumeric character, a text and the like.
[0166] The carrier substrate 2, as shown in FIG. 3a, further has a recess in the region 12. The region 12 is preferably cut out by means of stamping and/or by means of a laser. The region 12 is, as shown in FIG. 3a, formed rectangular. However, it is also possible for the region 12 to be formed oval, circular or patterned. The region 12, as represented schematically in FIG. 3a, further occupies a much larger surface area than the regions 10. The region 12 preferably has a surface area at least 4 times, preferably at least 8 times, further preferably at least 10 times, larger than that of the regions 10. The region 12 is preferably completed during the production of the document 1 before the perforation of the regions 10. The decorative ply 3 is visible in the region 12 when the document 1 is viewed from the underside of the carrier substrate 2. It is also possible here for the regions 10 to be connected to the region 12.
[0167] As shown in FIG. 3b, the carrier substrate 2 is perforated in the regions 10 and 11 such the decorative ply is visible in the regions 10 and 11 when the document 1 is viewed from the underside of the carrier substrate 2.
[0168] As shown in FIG. 3b, the region 10 here is preferably designed linear. The region 10 further represents a patter. The region 11 here is, as shown in FIG. 3b, likewise designed linear and forms a closed contour which represents a star-shaped pattern. The regions 10 and 11 here were perforated by means of a laser and have a line width of 300 m. It hereby becomes possible to uncover roughly prestructured features on the underside of the decorative ply, such as for example color surface areas or surface areas with optically variable effects, by means of the delicate perforations in the regions 10 and 11 of the carrier substrate 2 such that these are visible when the document 1 is viewed from the underside 5 of the carrier substrate 2.
[0169] As shown in FIG. 3b, the carrier substrate 2 is perforated both in the region 10 and in the region 11 such that the decorative ply is visible in the regions 10 and 11 when the document 1 is viewed from the underside 5 of the carrier substrate 2, wherein the region 11 has a different pattern from the region 10. Thus, when the document 1 is viewed from the underside 5 of the carrier substrate 2, the decorative ply defines the optical effects perceptible for an observer, in particular optically variable effects, both in the regions 10 and in the regions 11.
[0170] The document 1 shown in FIG. 3c has the regions 10 and 11. The region 10 corresponds to the region 11 of FIG. 3b, with the result that reference is made to the above statements with respect to the design of the region 10. The regions 11 are formed circular and have a diameter of from 50 m to 500 m. The regions 11 are arranged in a grid. The grid width advantageously corresponds substantially to the layer thickness of the carrier substrate 2. However, it is also possible for the grid width to be between 100 m and 5000 m, preferably between 500 m and 2500 m. In particular, the next spacing between two neighboring ones of the regions 11 is between 100 m and 5000 m, preferably between 500 m and 2500 m. Here the carrier substrate 2 was perforated in the regions 11 by means of a laser such that the decorative ply is visible in the regions 11 of the document 1 from the underside of the carrier substrate 2.
[0171] For example, one or more items of information haptically detectable for a person, in particular haptically detectable information about the value of a banknote or haptically detectable information with respect to the holder of a document, can be provided in Braille by such an arrangement of the regions 11.
[0172] The document 1 shown in FIG. 3d has the regions 10 and 11. The regions 11 here are designed linear and in each case form a contour closed in sections, in the shape of a triangle. The line width of the regions 11 in FIG. 3d is 250 m.
[0173] The region 10 is designed linear and likewise forms a contour closed in sections, in the shape of a circle. The line width of the region 10 in FIG. 3d is 350 m, with the result that in the decorative ply is visible both in the regions 11 and in the region 10 when the document 1 is viewed from the underside of the carrier substrate 2.
[0174] By a contour closed in sections is meant that the perforations are provided such that no completely enclosed regions 10 and/or 11 form, but rather the regions 10 and 11 are defined by contours interrupted in sections. For this purpose, the perforations are designed such that interruptions in the perforations are provided at regular and/or irregular spacings, wherein the carrier substrate is not removed in these interruptions, with the result that the regions 10 and/or 11 are joined together at least by one connection, preferably by several connections.
[0175] In FIGS. 3e to 3d the carrier substrate 2 is in each case completely perforated in the regions 10 and 11, in each case represented in black. However, it is also possible for, as explained previously, only in particular the opaque layers of the carrier substrate 2 to be perforated from the direction of the underside 5 of the carrier substrate 2, wherein the decorative ply is nevertheless visible when the document 1 is viewed from the underside of the carrier substrate 2, in particular as the non-perforated layers of the carrier substrate 2 are transparent. If the regions 10 and 11, like for example the region 11 in FIG. 3b or the region 10 in FIG. 3c, enclose a region of the carrier substrate 2, this region of the carrier substrate is not removed, as the perforation of the regions 10 and 11 is preferably effected after application of the decorative ply, with the result that the regions of the carrier substrate 2 enclosed by the regions 10 and 11 adhere to the decorative ply and are therefore not removed, i.e. the decorative ply fixes the regions of the carrier substrate 2 enclosed by a closed contour in place. Thus, it is possible for the regions 10 and 11 to form closed contours, without the enclosed regions of the carrier substrate falling out for example during the production process.
[0176] The document 2 shown in FIG. 3e has the regions 10 and 11. The region 11 here is designed linear and has a line width of 500 m. The region 10 forms, as shown in FIG. 3e, a closed circular contour and further has different line widths, with the result that the shape of a flower forms. The regions 10 and 11 are not connected to each other, with the result that the region 10 and the region 11 are separated by a region in which the carrier substrate 2 is not perforated by means of a laser. The line widths of the region 10 here vary between 500 m and 750 m. Such variations of the line widths can be generated for example by variations of the beam diameter in the focal point during the perforation of the carrier substrate 2. Here, the focus of the laser is advantageously altered, in particular by means of a lens system. As can be seen from FIG. 3e, the decorative ply is visible in the regions 10 and 11 when the document 1 is viewed from the underside 5 of the carrier substrate 2, wherein the decorative ply has different colors, in particular from the RGB color space, indicated by the different shading in FIG. 3e, in the regions 10 and 11. Thus, the decorative ply has a red color shade in the region 10 and a green color shade in the region 11. The regions 10 and 11, as shown in FIG. 3e, are further connected to each other.
[0177] It is further advantageous to separate the regions 10 and 11 from each other. The spacing between the two regions 10 and 11 will preferably be chosen such that possible positional tolerances of the different colors on the decorative ply 3 relative to the regions 10 and 11 are concealed or hidden below this spacing.
[0178] In FIG. 3e also the carrier substrate 2 is in each case completely perforated in the regions 10 and 11, represented shaded. However, it is also possible for, as already explained above, only in particular the opaque layers of the carrier substrate 2 to be perforated from the direction of the underside 5 of the carrier substrate 2, wherein the decorative ply is nevertheless visible when the document 1 is viewed from the underside of the carrier substrate 2, in particular as the non-perforated layers of the carrier substrate 2 are transparent. The region 10 forms a closed contour. As, however, the region 10 was not perforated by means of a laser until after the application of the decorative ply, here too the region of the carrier substrate 2 enclosed by the region 10 is fixed in place by the decorative ply. For further stabilization, it is possible to apply a transparent plastic ply, in particular in the region of the decorative ply applied to the upper side, to the underside of the carrier substrate 2.
[0179] FIG. 3f shows a region 10 and 11 respectively, which in each case are provided as delicate perforation, which are designed as a tendril-like motif, wherein the regions 10 and 11 are in each case joined together.
[0180] FIG. 4 schematically shows an enlarged section 40 of FIG. 3a. As shown in FIG. 4, each region 10 lies within a predefined region of surface 13, which is represented by the dashed lines in FIG. 4. Each of the regions 10 in which the carrier substrate is perforated by means of a laser and/or in which preferably the opaque layers of the carrier substrate are perforated by means of a laser preferably comprises at most 25%, preferably at most 10%, of the surface area of the respective predefined region of surface 13 when viewed perpendicular to a plane spanned by the carrier substrate.
[0181] By predefined is meant here a predetermined value or range of values or a predetermined shape or geometry, in particular which comprises 100% of the surface area. Thus, a predefined region of surface 13 is determined by a rectangle with a particular surface coverage in FIG. 4. This region of surface preferably corresponds to 100%, with the result that at most 25%, preferably at most 10%, of this predefined region of surface 13 is removed by perforations in the regions 10.
[0182] Furthermore, it is also possible for the decorative ply to completely cover the predefined regions of surface 13 when viewed perpendicular to a plane spanned by the carrier substrate.
[0183] FIG. 5a to FIG. 5c schematically show sectional representations of documents 1 which comprise a carrier substrate 2 and a decorative ply 3.
[0184] The document 1 shown in FIG. 5a here comprises the carrier substrate 2 as well as the decorative ply 3. The carrier substrate 2 is a single-layered paper substrate with a layer thickness of 80 m. However, as explained above, it is also possible for the carrier substrate 2 to be a multi-layered carrier substrate. With respect to such a design, reference is made to the above statements.
[0185] The decorative ply 3 shown in FIG. 5a comprises the layers 20, 21 and 22. The decorative ply 3 is applied to the upper side 4 of the carrier substrate 2 in regions.
[0186] The layer 20 is a thin-film layer system, which generates an optically variable effect dependent on the viewing angle. For this purpose, the thin-film layer system preferably has an interference layer structure. The interference layer structure preferably has a reflective layer, such as for example a metal layer, an absorption layer and a transparent dielectric spacer layer, which satisfies the /4 or /2 condition for a wavelength in the range of visible light. However, it is also possible for the thin-film layer system to be built up from a sequence of high- and low-refractive-index layers. As shown in FIG. 5a, the layer 20 here is arranged between the upper side 4 of the carrier substrate 2 and the layer 21.
[0187] By the /2 or /4 condition is meant the optical path difference, i.e. the path difference of two or more coherent waves of the incident light. This path difference is decisive for the occurrence of interference phenomena. If the optical path difference of two waves of equal wavelength and equal amplitude is precisely half a wavelength (and/or plus any desired integer multiple of the wavelength), the two partial waves cancel each other out. This weakening of intensity is called destructive interference. If the optical path difference is an integer multiple of the wavelength, the amplitudes of the two partial waves add up. In this case, there is constructive interference. In the case of values in between, a partial cancellation results.
[0188] The layer 21 comprises a replication varnish layer with microstructures molded at least in regions as well as a reflective layer at least in regions. The replication varnish layer consists for example of a thermoplastic varnish, into which the microstructures are molded by means of heat and pressure through the action of an embossing tool. It is further also possible for the replication varnish layer to be formed by a UV-crosslinking varnish and for the microstructures to be molded into the replication varnish layer by means of UV replication. The microstructures are molded onto the uncured replication varnish layer through the action of an embossing tool and the replication varnish layer is cured by irradiation with UV light before and/or directly during and/or after the molding. It is further advantageous if the replication varnish layer has a layer thickness of between 0.2 m and 4 m, preferably 0.3 m and 2 m, further preferably 0.4 m and 1.5 m. The microstructures molded in regions are here formed for example as sinusoidal diffraction gratings and generate an optically variable effect dependent on the viewing angle. However, it is also possible for the microstructures to be selected from the group Kinegram, holograms, blazed gratings, in particular asymmetrical sawtooth relief structures, diffraction structures, in particular linear sinusoidal diffraction gratings or crossed sinusoidal diffraction gratings or linear single- or multi-step rectangular gratings or crossed single- or multi-step rectangular gratings, mirror surfaces, matte structures, in particular anisotropic or isotropic matte structures, or combinations of these structures.
[0189] The reflective layer is preferably a metal layer. The metal layer is preferably a metal layer made of chromium, aluminum, gold, copper, silver or an alloy of such metals, in particular which is vapor-deposited under vacuum in a layer thickness of from 0.01 m to 0.15 m. It is further also possible for the reflective layer to be formed by a transparent reflective layer, for example a thin or finely structured metallic layer or an HRI or LRI layer (HRI=high refractive index, LRI=low refractive index). Such a dielectric reflective layer consists for example of a vapor-deposited layer made of a metal oxide, metal sulfide, titanium oxide, etc. with a thickness of from 10 nm to 150 nm.
[0190] In addition to the layers 20 and 21 shown in FIG. 5a, the decorative layer 3 can, as an alternative to the layers 20 and 21, also comprise other or also further layers, in particular selected from the group one or more color layers, one or more layers with optically variable pigments, one or more thin-film layer systems, one or more layers generating an optically variable effect, one or more layers with color pigments and/or dissolved dyes and/or one or more layers with microstructures, in particular wherein the layers generate at least one color effect in the range of the wavelengths visible to the human eye, in particular in the wavelength range of from 400 nm to 800 nm, when the document is viewed from the underside of the carrier substrate.
[0191] The layer 22 is an adhesion layer. The adhesion layer is preferably a hot- or cold-glue layer, which comprises in particular acrylates, PVC, polyurethane or polyester. The layer 22 is a hot-glue layer with a layer thickness of from 0.1 m to 10 m, preferably of from 0.5 m to 5 m. The decorative ply 3 shown in FIG. 5a is therefore in particular a transfer ply of a hot-stamping film. However, it is also possible for the decorative ply to be a transfer ply of a cold-stamping film or for the decorative ply to be a laminating film.
[0192] As shown in FIG. 5a, the carrier substrate 2 and the layer 22 of the decorative ply 3 are perforated in the regions 10 by means of a laser such that the layer 20 is visible in regions 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. Here, not only the carrier substrate 2, but further also the layer 22, was thus perforated by means of a laser. Further, as shown in FIG. 5a, the carrier substrate 2 and the layers 22 and 20 have been perforated by means of a laser in the region 11. The layer 21 has hereby been uncovered in the region 11 from the underside 5 of the carrier substrate 2, with the result that the layer 22 is visible in the region 11 when the document 1 is viewed from the underside 5 of the carrier substrate 2. Therefore, if the document 1 of FIG. 5a is viewed from the underside 5 of the carrier substrate, the layer 20 is visible in the regions 10 and the layer 21 is visible in the region 11.
[0193] FIG. 5b corresponds to FIG. 5a, with the difference that the decorative ply in FIG. 5b further comprises the protective varnish layer 23. The protective varnish layer is preferably a layer of PET (=polyethylene terephthalate), PEN (=polyethylene naphthalate), PE (=polyethylene), PI=(polyimide), PP (=polypropylene), PC or PTFE (=polytetrafluoroethylene). The layer thickness of the protective varnish layer is advantageously between 0.5 m and 30 m, preferably between 3 m and 10 m. The protective varnish layer shown in FIG. 5b is a layer of PET with a layer thickness of 16 m. With respect to the further design of the layers shown in FIG. 5b, reference is made here to the above statements.
[0194] The document 1 shown in FIG. 5c comprises a carrier substrate 2, a decorative ply 3, as well as a transparent plastic ply 7. The decorative ply 3 of FIG. 5c corresponds to the decorative ply of FIG. 5a, with the difference that the decorative ply 3 does not comprise an adhesion layer 22 and is applied directly to the carrier substrate 2. The transparent plastic ply 7 is, as shown in FIG. 5c, applied to the underside 5 of the carrier substrate 2 in the region in which the decorative ply 3 is applied to the upper side 4 of the carrier substrate 2. As shown in FIG. 5c, the transparent plastic ply 7 and the carrier substrate 2 are perforated in the regions 10 and 11 by means of a laser. The layer 20 is further perforated in the region 11, with the result that the layer 21 is visible in the region 11 when the document 1 is viewed from the underside 5 of the carrier substrate 2. With respect to the further designs of the layers, reference is made here to the above statements.
[0195] FIG. 6a to FIG. 6d schematically show a document 1.
[0196] In FIG. 6a the document 1 is shown in top view when the document 1 is viewed from the upper side 4 of the carrier substrate 2. As shown in FIG. 6a, the document 1 has the decorative ply 3, which is applied to the upper side 4 of the carrier substrate 2.
[0197] In FIG. 6b the document 1 is shown in top view when the document 1 is viewed from the underside 5 of the carrier substrate 2. The carrier substrate 2 is perforated in the regions 10 by means of a laser such that the decorative ply 3 is visible in the regions 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. The regions 10 are further arranged on the side of the carrier substrate opposite the decorative ply 3, which is indicated by the dashed lines. As shown in FIG. 6b, the regions 10 here are designed linear and arranged in a line grid.
[0198] FIG. 6c schematically shows an enlarged section 41 of FIG. 6b. As shown in FIG. 6c, the regions 10 represented in black, in which the carrier substrate 2 is perforated by means of a laser such that the decorative ply 3 is visible in the regions 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2, are designed linear and arranged in a grid. The grid width of the line grid advantageously corresponds substantially to the layer thickness of the carrier substrate 2. However, it is also possible for the grid width of the line grid to be between 30 m and 250 m, preferably between 50 m and 100 m, further preferably between 70 m and 90 m. The grid width of the line grid shown in FIG. 6b and FIG. 6c is 80 m.
[0199] FIG. 6d illustrates the effect of the perforated regions 10 of the carrier substrate 2 shown in FIG. 6b and FIG. 6c when the document 1 is viewed from the underside 5 of the carrier substrate 2. If the document 1 is viewed substantially perpendicular to a plane spanned by the carrier substrate 2, the decorative ply 3 is visible in the regions 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. If the document 1 is tilted and viewed for example at its lateral viewing angle of more than 35, preferably more than 25, from the underside 5 of the carrier substrate 2, the decorative ply 3 is no longer visible. The decorative ply 3 is thus visible to an observer depending on a lateral viewing angle. If the decorative ply 3 is for example a color layer, a color change effect dependent on the viewing angle can hereby be generated in the regions 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2.
[0200] FIG. 7a to FIG. 7c schematically show method steps for producing a document 1.
[0201] As shown in FIG. 7a, the carrier substrate 2 is provided first. With respect to the design of the carrier substrate 2, reference is made here to the above statements. In a next step, as shown in FIG. 7b, the decorative ply 3 is applied to the upper side of the carrier substrate 2. The decorative ply 3 is for example a layer with color pigments which generate a green color impression. With respect to further possible designs of the decorative ply 3, reference is made here to the above statements. The application of the decorative ply 3 here is preferably effected by means of hot-stamping, cold-stamping or laminating, i.e. the decorative ply can be for example a transfer ply of a hot-stamping film, which is applied to the carrier substrate 2 by means of hot-stamping, and/or a laminating film, which is applied to the carrier substrate 2 by means of hot-gluing. In a further step, the carrier substrate 2 is then perforated in the region by means of a laser. This makes it possible for the decorative ply 3 to be visible when the document 1 is viewed from the underside 5 of the carrier substrate 2. In FIG. 7c the carrier substrate 2 is perforated completely by means of a laser. However, it is also possible for the carrier substrate 2 not to be perforated completely and for the decorative ply 3 still to be visible when the document 1 is viewed from the underside 5 of the carrier substrate 2. Thus, the carrier substrate can comprise for example a transparent plastic ply, which is arranged between the upper side 4 of the carrier substrate 2 and the decorative ply 3 and therefore, because of its transparency, does not impair the visibility of the decorative ply 3 when the document 1 is viewed from the underside 5 of the carrier substrate 2. In FIG. 7c the perforation of the carrier substrate 2 is effected from the direction of the underside 5 of the carrier substrate 2.
[0202] By perforation is meant here the complete removal here of the carrier substrate 2. The perforation here is preferably effected on the basis of laser cutting and/or laser ablation, with the result that the carrier substrate 2 is worn away and/or ablated and/or burnt up and/or evaporated residue-free in the region 10. A gas laser, in particular a CO.sub.2 laser, was used to perforate the carrier substrate 2 according to the embodiment example of FIG. 7c. The laser power here is advantageously at least 250 W, preferably at least 300 W, further preferably at least 350 W. It is further advantageous if the wavelength of the laser is between 9.35 m and 10.25 m. The region 10 of the carrier substrate 2 in FIG. 7c was perforated by means of a CO.sub.2 laser with a laser power of 300 W and a wavelength of 10.6 m.
[0203] The laser beam here is preferably deflected along and/or onto the region 10 of the carrier substrate by means of moveable mirrors, in particular by means of a laser scanning module.
[0204] The beam diameter of the laser in the focal point here is at least 20 m, preferably at least 50 m, particularly preferably at least 100 m. However, it is also possible to widen the laser beam by means of a lens system such that the beam diameter in the focal point is at most 2 mm, preferably at most 1 mm. The region 10 shown in FIG. 7c was generated by means of a laser beam which has a beam diameter of 200 m in the focal point, with the result that the width of the region 10 is likewise essentially 200 m.
[0205] The laser here is preferably further operated at a writing speed of 3000 mm/s, preferably of 2200 mm/s, further preferably of 2000 mm/s. It is further possible for the laser to have a writing surface area of 200200 mm, preferably of 150150 mm, further preferably of 140140 mm.
[0206] The carrier substrate 2 here is expediently transported at a running speed of 200 m/min, preferably of at most 130 m/min, further preferably of 120 m/min, still further preferably of 60 m/min. It is hereby ensured that the carrier substrate 2 is perforated or removed residue-free in the region 10 depending on the writing surface area of the laser, the writing speed of the laser and/or the laser power.
[0207] FIG. 8a to FIG. 8c schematically show method steps for producing a document 1.
[0208] As shown in FIG. 8a, the carrier substrate 2 is provided in a first step. With respect to the design of the carrier substrate 2, reference is made here to the above statements.
[0209] The decorative ply 3 is applied to the carrier substrate 2 in a further step according to FIG. 8b. The application is preferably effected here by means of hot-stamping. The decorative ply shown in FIG. 8b here comprises the layers 20, 21, 22 and 23. The layer 22 is a hot-glue layer, which comprises in particular acrylates, PVC, polyurethane or polyester and by means of which the decorative ply 3 is firmly applied to the upper side 4 of the carrier substrate 2. The layer 20 is a color layer which has a blue color shade. The layer 21 is likewise a color layer, but which has a yellow color shade. Such color layers can be generated for example by layers which are provided with the corresponding color pigments and/or dissolved dyes. However, it is also possible for the layers and 21 to be for example layers which in each case generate a different optically variable effect. Thus, it is possible for example for the layers 20 and 21 to have differently formed microstructures which in each case generate an optically variable effect. The layer 23 is a protective varnish layer. With respect to the design of the layer 23, reference is made here to the above statements.
[0210] It is further advantageous if the step of applying the decorative ply 3 to the upper side 4 of the carrier substrate 2 further comprises the following step:stretching the decorative ply 3 before application of the decorative ply 3 to the carrier substrate 2, wherein the stretching of the decorative ply 3 is between 0% and 10%, preferably between 0% and 5%. Here, the stretching of the decorative ply is preferably generated by a stretching of the transfer film or the laminating film which comprises the decorative ply 3 as transfer ply. Through a corresponding stretching, a motif spacing of motifs located on the decorative ply 3 is made to match the spacings of security features located on the carrier substrate 2. Values for the tolerance between the decorative ply 3, in particular between motifs located on the decorative ply 3, and the perforations in regions 10 and 11 of between 0.1 mm and 2.0 mm, preferably between 0.3 mm and 1.5 mm, can hereby be achieved.
[0211] After the decorative ply 3 has been applied, the carrier substrate 2 and the layer 22 of the decorative ply 3 are, as shown in FIG. 8c, perforated in the region 10 by means of a laser. The blue color layer 20 is hereby uncovered, with the result that a blue color impression is perceived in the region 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. If the region, as shown above for example in FIG. 3a, is designed linear and forms a pattern, the linear pattern appears blue to an observer. Further, as shown in FIG. 8c, the carrier substrate 2 and the layers 22 and 20 of the decorative ply 3 are perforated by means of a laser in the region 11. The yellow color layer 21 is hereby uncovered, with the result that a yellow color impression is perceived in the region 10 when the document 1 is viewed from the underside 5 of the carrier substrate 2. It is possible here for the region 10 and the region 11 to be connected and/or for the regions 10 and 11 to overlap at least in regions. This makes it possible for example to uncover multi-colored motifs in a targeted manner from the underside 5 of the carrier substrate 2, wherein the chromaticity and the optical impression of these motifs are defined by the uncovered layers 20 and 21 decorative ply 3.
[0212] It is also possible here to generate the regions 10 and 11 by means of different lasers. Thus, at least two lasers are used, which are preferably matched to each other such that the production process can be shortened.
[0213] After the perforation of the carrier substrate 2 and the layers 22 and 20 in the regions 10 and 11, it is possible for the method further to comprise the following step:applying one or more, in particular transparent, plastic plies, which are applied in particular to the upper side and/or underside of the carrier substrate 2. The stability or robustness of the document 1 against environmental influences can hereby be further improved. The perforated regions 10 and 11 can also be sealed hereby on the underside 5 of the carrier substrate 2, in order to prevent ingress of impurities.
[0214] It is also possible for the step of applying the decorative ply 3 and/or the step of perforating the carrier substrate 2 and the layers 22 and 20 further to comprise the following steps: [0215] detecting the positional data of a security feature of the carrier substrate 2, in particular a watermark; [0216] optionally correcting the detected positional data by means of an algorithm to form corrected positional data; [0217] introducing the control openings into the carrier substrate 2 on the basis of the detected positional data, in particular on the basis of the corrected positional data, in particular by means of a laser.
[0218] FIG. 9a and FIG. 9b schematically show devices 19 for carrying out the method.
[0219] FIG. 9a schematically shows a device 19 for carrying out the method.
[0220] The device 19 here has the application device 31a, by means of which a decorative ply is applied to the carrier substrate 3. The device 19 further comprises a laser for perforating at least one layer of the carrier substrate 2, and a transport device 30, which serves to transport the carrier substrate 2. Thus, it is possible for example for the transport device to comprise a storage roll, on which the carrier substrate 2 is wound. Alternatively, it is also possible for the transport direction to be designed for transporting the carrier substrate 2 in sheet form.
[0221] The laser 32 is preferably a gas laser, in particular a CO.sub.2 laser, and/or a solid-state laser, in particular an Nd:YAG laser. The laser power is advantageously at least 250 W, preferably at least 300 W, further preferably at least 350 W. It is further advantageous if the wavelength of the laser 32 is between 9.35 m and 10.25 m. Thus, for example, a CO.sub.2 laser with a laser power of 300 W and a wavelength of 10.6 m can be used. The laser 32 preferably has a writing speed of 3000 mm/s, preferably of 2200 mm/s, further preferably of 2000 mm/s.
[0222] It is further possible for the laser 32 to have a writing surface area of 200200 mm, preferably of 150150 mm, further preferably of 140140 mm.
[0223] The transport device 30 is expediently designed such that the carrier substrate 2 is transported at a running speed of 200 m/min, preferably of 130 m/min, further preferably of 120 m/min, still further preferably of 60 m/min.
[0224] FIG. 9b schematically shows a device 19 for carrying out the method, comprising a transport device 30, a sensor unit 33, a computer unit 34, a printing unit 35 and a stamping unit 36.
[0225] The carrier substrate 2 is first fed to the sensor unit 33 by the transport unit 30. The sensor unit 33, in particular an optical sensor unit for detecting radiation in reflected light and/or in transmitted light in one or more visible wavelength ranges or the entire visible wavelength range and/or in one or more ultraviolet wavelength ranges or the entire ultraviolet wavelength range and/or in one or more infrared wavelength ranges or the entire infrared wavelength range, is for example a photodetector, a CCD sensor or a CMOS camera, and makes it possible to detect the position of the at least one security feature of the carrier substrate 2, in particular a watermark and/or a printed feature. The detected position of the security feature is transmitted to a computer unit 34, which determines corrected positional data from the detected positional data by means of an algorithm. The position of the carrier substrate 2 can be matched to the corrected positional data by means of an actuator, not represented. The actuator can thus correct the location of the carrier substrate 2 in the plane relative to the positions of the subsequent units, in particular the stamping unit 36 and/or the laser 32, to generate control openings.
[0226] The carrier substrate 2 is then transported into the stamping unit 36, by means of which, after successful location correction, control openings and/or window openings which are extensive in relation to the perforations generated by means of the laser 32 can be introduced into the carrier substrate, as already explained above. It is also possible for the introduction of control openings to be effected by means of a laser.
[0227] The carrier substrate 2 is then fed to the application device 31a, by means of which a decorative ply is applied to the carrier substrate 2. Here too, the location of the carrier substrate 2 can be adapted using the corrected positional data. The carrier substrate 2 is then fed to the laser 32 for the perforation of at least one layer of the carrier substrate 2. With respect to the design of the laser 32, reference is made here to the above statements.
[0228] The carrier substrate 2 is then fed to the application device 31b, by means of which a transparent plastic ply is applied to the underside of the carrier substrate 2. The regions perforated by means of the laser 32 and/or the window openings introduced by the stamping unit 36 can hereby, as stated above, be sealed. Here too, it is possible to adapt the location of the carrier substrate 2 using the corrected positional data.
[0229] Finally, the carrier substrate 2 is fed to the printing unit 35, in order to print for example colored patterns and/or alphanumeric characters on the carrier substrate 2. Here too, it is possible to adapt the location of the carrier substrate 2 using the corrected positional data.
[0230] Further machining units can follow, such as for example at least one further printing unit, at least one further application device and/or at least one vapor-deposition device and/or at least one moistening unit, etc., which are not shown here, however. Finally, the carrier substrate 2 can also be fed to a cutting unit, in order to divide the carrier substrate 2 into individual panels.
