Definitions

  • the invention describes a data carrier consisting of various laminate layers, in which visually irreversible changes in the interior of the data carrier are brought about by means of a laser beam in such a way that when viewed from different perspectives, different graphic structures are recognizable and can be used to verify the authenticity of the data carrier and manufacturing processes thereof.
  • the present invention relates to a novel method and an inexpensive method for laser processing systems for producing wiggle-like effects on laminate composites with generally transparent or translucent cover foils.
  • EP 0 216 B1 and EP 0 219 012 B1 describe the basic principles of such methods and processes, a polycarbonate film composite of several thin films with security prints in between being produced by lamination in the usual credit card format.
  • the authenticity features are written into the card network by means of a laser beam.
  • a top of the card is provided with a so-called lens grid in a melting process in a thermal transfer press.
  • the upper edge of the lens grid is preferably arranged in one plane with the card body, so that the lens surface is protected to a certain extent.
  • the lenses of the lenticular screen formed in this way now direct a laser beam in an oblique orientation to the card surface, which is focused in the area of the respective lens and directed onto a specific inner plane of the card.
  • defined darknesses are created - as an authenticity feature. In this way, at least two authenticity features, which are dependent on the viewing direction of the observer, can be written into the card.
  • lens diameters can be calculated very easily on the basis of the refractive indices of thermoplastics that are available and technically possible, and lens diameters of approximately 250 to 400 micrometers are usually used, which are arranged in a grid shape next to one another in a cylindrical shape. Grid distances are used which are slightly below the lens diameter, so that the lenses partially overlap in the edge area. This results in embossing depths of typically 70 to 100 micrometers. With a refractive index of approximately 1.5, the irreversible and visible material changes lie at a depth of, for example, 200 to 450 micrometers in the card network and are therefore well protected against mechanical damage and counterfeiting.
  • European Patent EP 0 219 012 B1 now further states that the change in the optical properties is limited to areas (pixels) whose radial extent is smaller than the diameter of a single lens, and that the information that is obtained using laser beams were recorded from at least two different directions in the lenticular area, can be read under the same directions in limited angular ranges and / or recorded by measurement.
  • a disadvantage of the production of such lenticular screens is the fact that a relatively deep embossing during the lamination process - cf. EP 0 842 791 A2 - and / or even more complex in the single card - cf. EP 0 843 281 A2 - has to be carried out, in the single card in general the already graphically designed and laminated card generally results in a relatively strong distortion or a strong material flow due to the material displacement to form the lens grid.
  • stamping press plates In the case of stamping by means of press plates in a multi-day thermal transfer press, it must also be taken into account that such stamping press plates are extremely expensive and the entire process is therefore very expensive.
  • the object of the invention is accordingly a simplification of the embossing process of any customer-specific designed lenticular structure to achieve a comparable or improved wiggle effect due to laser processing and an additional increase in the complexity of the method and thus increase the difficulty of counterfeiting such a wiggle-like effect.
  • the lens system is therefore no longer used to write in the authenticity features.
  • This has the advantage that the cards are labeled with the two (or more than two) different authenticity features in a relatively simple labeling process and that the lens system is only subsequently generated when the card is finally finished.
  • the necessary information is thus introduced into the card body without a surface relief or without an optical lens effect in such a way that the information previously introduced is optically recognized or measured by at least two different directions from a viewer and / or from a technical point of view through a subsequent application of appropriately coordinated surface reliefs or optical lens effects can be detected.
  • Such a method therefore does not require a laser beam from at least two different directions, as mentioned in the documents EP 0216947 B1 and EP 0 219 012 B1, but rather the closely adjacent information can be juxtaposed in the desired depth by means of a very small laser beam focusing or location can be arranged.
  • the subsequently applied surface relief must therefore be applied in the correct position so that the focal point of the optical lenses enables the information generated by laser beams to be recognized and read out.
  • the precise application of the lenticular grid is not of crucial importance. If the lenticular array is only applied offset to the laser image underneath, the readout will only change the direction of readout. One image can then possibly only be recognized from a viewing angle of 40 degrees to the card surface, while the other image can be recognized at an angle of 70 Degree is recognized. The quality or the visibility of the reading is not affected.
  • An important feature of the invention is that certain authenticity features are first introduced into a laser-capable structure by means of laser inscription, these authenticity features being generally referred to as elements.
  • these elements can be introduced by blackening in the area of a laserable film, a volume element or a multilayer laminate, or color structures can also be introduced.
  • Color structures of this type are generated by laser irradiation and by a corresponding chemical conversion process, so that different color impressions arise in the corresponding irradiated volume element.
  • Nd-YAG laser light at preferably 1064 nm, that is to say in the infrared range, so that when using so-called laser-transparent or transparent films and also conventional IR-transparent ones Printing inks, the laser beam passes through such laminate layers without significant thermal stress and only causes blackening due to carbonization or carbonization in laminate films and / or printing inks with high IR absorption.
  • the authenticity features can also be achieved by a photochemical reaction with a suitably selected laser wavelength (s) and corresponding, suitable pigments or fillers or printing ink combinations in the form of color effects.
  • the invention is therefore not limited to the introduction of only black and white colored elements, but any colored elements can also be introduced into a volume element of a data carrier.
  • the desired tilting effect is now achieved in that the corresponding microstructures, with which it is possible to view the introduced elements differently from two different angles, are applied subsequently only after the introduction of such elements by means of a laser beam into a volume element of a data carrier.
  • microstructures in the form of applied hologram layers which must be at least translucent, wherein such applied hologram-effective microstructures can work both with a diffraction effect and with a refraction effect
  • the optically active lens system consists of Fresnel lenses.
  • the strong material displacements for the production of cylindrical lenses according to the prior art are avoided by the division into lenses arranged in a stepped manner (Fresnel lenses), and this results in great design freedom.
  • the advantage is that when producing such a Fresnel lens embossing with the reduction of the embossing depth by a factor of 2 to 10, only very short cycle times are required compared to conventional lens systems.
  • the Fresnel lenses can therefore be applied to an already finished single card without any significant material displacement and thus without optical distortion problems, and the card previously labeled with the laser can be further processed with the existing positioning system to produce the lens system.
  • a surface embossed with a Fresnel lens structure is additionally provided with a so-called high index coating in such a way that an approximately lambda / 4 effect is preferably achieved.
  • Diffraction effects on the grating structure are therefore used to read out the information below from different viewing directions. What is important here is the wavelength variants of the laser and the aperture-shaped intensity distribution of the laser beam, which leads to novel effects.
  • the small thickness in the range from less than 2 to a maximum of 10 micrometers of such holographic elements has proven to be particularly advantageous.
  • the two-channel holograms mentioned are merely a preferred embodiment when it comes to introducing two different microstructures into the surface (hologram layer) of the card.
  • the present invention is not limited to this, but multichannel holograms can also be attached, in which case more than two microstructures are attached and the entire optical elements which lie below in the volume element of the data carrier are then from more than one two viewing angles visible separately from each other.
  • toothed grating with a sawtooth structure is understood to mean so-called “blazed” grating.
  • gratings are preferred because they have a higher diffraction efficiency than sinusoidal gratings.
  • volume holograms are used, which are typically 10 ⁇ m thick layers or foils.
  • Different effects can be effective alone and in combination. Namely a diffraction without refraction or a combination of both physical effects, i.e. diffraction and refraction.
  • Usual kinegram or hologram foils can realize a maximum of 0.5 my steps; with laminating TKO films, however, 2 to 3 my structures would very likely be realizable.
  • the three methods mentioned can now be produced in such a combined manner that initially conventional laminate cards with high-gloss surfaces are produced and these are preferably provided with the information necessary for a wobble security image in a laser engraving process and the corresponding optical microstructures are subsequently applied, which are optionally embossed as a Fresnel lens structure and / or are embossed as corresponding additive optical microstructures. Attention should be paid to a translucent design of all these optical elements.
  • the laser processing process according to the invention is faster because tilting the card and / or the laser extends the process.
  • Another advantage is that there is no need to have exactly focusing lenses which automatically focus the laser beam at a depth of about 100 to 300 micrometers in order to be able to write the authenticity elements at all in a defined, constant depth.
  • the lens and / or diffraction system subsequently applied only has to permit an approximate reading of the information from different (not necessarily complementarily identical) viewing directions.
  • it is preferred if, during the subsequent application of the optical element, to a relatively precise registration, i.e. Positioning of a few 5 micrometers is taken into account.
  • Nd YAG laser with 1,064 nm and a focus of typically 50 micrometers (preferred range between 25 to 300 micrometers).
  • Color generation of color effects by laser, i.a. photochemical effects are used, since thermal effects in a thermoplastic laminate structure are not particularly suitable.
  • the color effect can, on the one hand, enable very special wiggle effects through such new systems based on appropriately selected layers (pigments, etc.). However, a color effect can also be obtained holographically.
  • Aperture a new generation of lasers will have apertures and very different geometric laser points can be generated with it.
  • Laser pulse length with the new laser systems extremely short pulses can be generated, or with the number of pulses / length the blackening / multiple labeling can be realized.
  • the advantage of laser processing is that the tilting or wobble effect cannot be verified (resolved) in one operation without using an optical system.
  • the present invention is based on the knowledge that not only the known lens raster in the form of cylindrical lenses allow interesting and difficult to falsify effects for the realization of a wobble image, but also that spherically arranged Fresnel lenses or holographically arranged structures when using special laser Optics enable such effects and the type of arrangement of the lenses from a regular to a statistical distribution is possible. Modulated and, in particular, frequency-modulated distributions of the lenses can also be selected.
  • the corresponding embossing stamps or embossing plates or holographic layers must be adjusted or matched to the laminate layer structure and here in particular to the thicknesses of the individual layers with the corresponding refractive indices or to the refraction and diffraction properties.
  • a further exemplary embodiment of the invention relates to the fact that a holographic microstructure can be introduced into a volume of the multi-layer data carrier by means of different insertion methods.
  • a transmission surface hologram is laminated as a film body in the multilayer card structure, where it forms a specific volume element of this data carrier.
  • a volume hologram can be introduced, which is also introduced into a film and this is laminated in the card assembly.
  • Such volume holograms are typically photopolymer layers.
