Definitions

  • the invention relates to a method for producing a valuable or security product in which Braille personalization is present.
  • the invention also relates to a valuable or security product which is produced using such a process.
  • Value or security documents can be, for example, a personal document, a check card, a non-personalized authorization card, such as a ticket or a means of payment, or a value or security element intended for product security.
  • Braille writing for valuable or security documents, with which, for example, data in plain text can be reproduced again in Braille.
  • Braille fonts on card bodies are currently only applied superficially by embossing with static content or only subsequently by inkjet printing on a card or by a sticker on the valuable or security product.
  • an outer protective layer is applied before laser processing on the transparent, non-laserable printing layer. It is possible that additional intermediate layers are also available.
  • the stability of at least one Braille character can be specifically influenced via the layer structure.
  • a (gas) bubble is preferably formed between the individual layers, which can then be detected tactilely through the individual layers.
  • the shape of the “bubble” formed in this way and the resulting Braille character can be specifically influenced via the layer structure, although this becomes smaller as the number of layers increases.
  • cover layer that is only partially opaque is applied to the laserable film layer.
  • the cover layer allows underlying areas to be specifically covered with the opaque sections.
  • the cover layer is opaque in at least one of those places where a blackening was introduced by the laser beam in the underlying laser-capable film layer.
  • the blackening of the laser can be specifically “hidden” as a security feature.
  • the opacity of the material can be a film property that is achieved using fillers. Alternatively or additionally, the opacity of the material can be achieved using a suitable printing process. It is advantageous if the materials used do not interact or only interact slightly with the wavelength of the laser used.
  • the shape of the individual Braille dots of the Braille character can be specifically adjusted by using a laser with a scanner device and/or suitable diffractive optics. For example, it is possible to create elliptical, in particular circular, Braille dots for realizing the Braille character or also rectangular, in particular square, Braille dots.
  • the cross section, and thus the point geometry or point profile, of the individual Braille points of the Braille character can also be changed in a targeted manner.
  • a material selected from polyester can be considered as a transparent laser-capable film layer. These materials have proven to be advantageous for processing with a laser.
  • a diode or fiber laser is preferably used for laser processing. This can be formed as a femtosecond laser or as a picosecond laser. This ensures that only a small amount of heat is introduced into the layer structure through the pulsed operation and that the intensity of the laser beam reaches exactly where it is needed.
  • the valuable or security product can be a valuable or security document or a security element, i.e. an element that is connected, for example, to an object to be protected against imitation, counterfeiting or falsification, for example a sticker, label or the like.
  • valuable or security products include a passport, an identity card, a driver's license or another ID card or an access control card, a check card, a bank card, a credit or cash payment card, a customer card, a health card, a chip card
  • a company ID card, a credential, a membership card or another ID document should be considered, ensuring that it has at least one Braille character.
  • the valuable or security product is in ID 1, ID 2, ID 3 or in some other format, for example in booklet form, such as a passport-like item.
  • the valuable or security product is generally a laminate made up of several document layers that are precisely connected to one another under the influence of heat and increased pressure. These products should meet standardized requirements, for example ISO 10373, ISO/IEC 7810, ISO 14443.
  • the product layers preferably consist of a carrier material that is suitable for lamination.
  • the valuable or security product can preferably be formed from a polymer which is selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminal disubstituted bis (hydroxyphenyl) cycloalkane, polyethylene terephthalate (PET), their derivatives, such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS) , polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and their
  • the product can also be made from several of these materials. It preferably consists of PC, PVC and PET.
  • the polymers can either be filled or unfilled. In the latter case, they are preferably transparent or translucent. If the polymers are filled, they are opaque.
  • the above information relates both to films to be bonded together and to liquid formulations that are applied to a preliminary product, such as a protective or top coat.
  • the product is preferably made from three to twelve, preferably four to ten, films.
  • the films can also carry print layers. A laminate formed in this way can then be covered on one or both sides with the protective or top coat or with a film.
  • the film can in particular be a volume hologram, a film with a surface hologram (for example a kinegraphic element) or a scratch protection film.
  • Overlay layers formed in this way protect a security feature arranged underneath and/or give the document the required abrasion resistance.
  • the valuable or security document 100 can be a personal document, such as a passport, an identity card, an access card or the like, a check card or a banknote or another document. All of the following examples are described using such a map as representative of other types of documents.
  • the valuable or security product 100 is shown in the form of an identity card, which includes a core layer 102, which itself has been assembled, for example, as a laminate made up of several internal polymer layers 130.
  • the polymer layers can consist of PC and/or PET.
  • the individual layers can be unfilled or filled with fillers. In the latter case they are opaque, otherwise transparent.
  • the layers can preferably be connected to one another in such a way that they form a monolithic block which is virtually impossible to split.
  • the outer layers 114 of the card may be formed as a final plastic protective film or may consist of a protective varnish applied to the card after lamination.
  • the plastic protective film or protective varnish is transparent so that the information underneath is visible from the outside.
  • one or more printing layers 112, for example of a portrait image 120 remain visible, which are preferably arranged directly next to or behind the outer layer 116.
  • the valuable or security product 100 has a top 116 and a bottom 118.
  • the data in the first and second data fields 122, 124 are produced by printing layers which lie on an outer layer of the document, but directly under the outer protective layer 114.
  • the data in a third data field 126 and in a fourth data field 128 reproduce the personalization data present in plain text again in Braille.
  • the individualization can be created, for example, using a card structure Figure 3 to recognize, wherein the laser beam shown on the left has a low intensity for merely optically changing the laser-capable transparent film layer 106, and wherein the laser beam shown on the right has a high intensity, which is higher than the low intensity.
  • an opaque non-laser-capable printing layer 112 is applied to the core layer 102, with a transparent laser-capable film layer 106 being applied to the non-laser-capable printing layer 112.
  • the result of laser processing according to Figure 3 is for example in Figure 4 shown, the laserable film layer 106 being optically personalized or individualized at those points where the laser beam is at a low level Performance was focused (left).
  • a high-intensity laser beam causes foaming or a large amount of fumes, which causes a part to protrude above the surface and can therefore be detected tactilely (right).
  • a further layer structure of the valuable or security product 100 can be seen, which includes several transparent layers.
  • the laser-capable film layer 106 is applied to the core layer 102, which in turn is covered by a transparent, non-laser-capable printing layer 112.
  • An outer protective layer 114 is applied to the pressure layer 112.
  • the left laser beam illustrates that a low intensity is used for the optical individualization of the valuable or security product 100.
  • a laser with higher intensity is used to form a tactile Braille character 110.
  • Figure 6 shows the result of the laser processing, with a bubble 134 being created in the area of the layers that were processed with the high-intensity laser, which extends across the individual layers.
  • a Braille dot is formed that can be detected tactilely on the surface.
  • the dot shape can be modulated using different power densities, so that gray values can also be achieved for the Braille dots.
  • the shape of the Braille dots can be customized so that ellipses, especially circles or even rectangles, especially squares, can be present as Braille dots.
  • the edges of the individual Braille points can also be modulated.
  • the invention has the advantage that the optically detectable, tactilely non-detectable, individualizations on the valuable or security product 100 can be carried out with one and the same laser device, with the tactilely detectable information for the Braille 110 also being provided with the Lasers can be incorporated into the card structure.
  • the use of the laser for optical information and for tactile information is reduced the number of manufacturing steps and facilitates the production of the valuable or security product 100.
