Definitions

  • the invention relates to a method for producing a security document, in which information is or are coded by using holes in a substrate.
  • Security documents are all those documents that have features that make it impossible or at least significantly complicate the copying and / or falsification of a document. Such features are referred to as security feature.
  • Security documents include, for example, identity documents such as passports, identity cards, access cards, driver's licenses, labels, tickets, but also such documents embodying values such as postage stamps, banknotes, stocks or even credit and debit cards, calling cards, to name but a few.
  • security documents have a very high interest in preventing the information from being manipulated after being incorporated in or into the document. Tampering may consist of removing information, changing the information or adding the information.
  • a laser marking method is known in which a discoloration of an additive added to a substrate of a security document is discolored by means of laser light, which comprises at least one organic or inorganic pigment and / or one polymer-soluble dye.

  • the information is visible in transmitted light. It is also described to refill the microchannels after their introduction. From the DE 199 34 434 A1 It is also known to bring perforations of different shape and size in a security document.
  • a portable data carrier such as a smart card in which a security feature by introducing recesses, filling the recesses with a translucent material and curing of the translucent material is generated, wherein the translucent material contains components that by UV and or IR irradiation for Luminescence are excitable.
  • a document having a security feature that is in the form of a perforation pattern is known. This includes shades of gray when viewed against a light background, the document being of a material that transmits light to a limited extent. At least some of the perforations that form part of the perforation pattern extend over only a portion of a thickness of the document.
  • the thickness of the remaining portion of the document at the location of the perforation is modulated according to the gray scale of an image to be displayed.
  • a carrier is known that includes a printed individualizing pattern that is legible to the human eye. Furthermore, the carrier has an individualizing pattern, which is also formed by perforations, which are introduced by means of a laser and are perceptible to the human eye, wherein the two patterns are related to one another.
  • the perforated pattern has the same characters as the printed pattern.
  • a tamper-proof document that has a security feature in the form of a perforation pattern.
  • the document comprises layers of different colored material, whereby a color becomes visible depending on the depth of the perforation.
  • the US 4,544,183 B1 describes methods according to the preamble of claim 1 and a multi-layer security document with a changeable via an irradiation of light having a wavelength of 3500 ⁇ to 5000 ⁇ in terms of the color impression caused color layer.
  • This color layer is added an embodiment after engraving the surface applied so that the variable color fills engraved depressions.
  • the US 6,328,342 B describes a data carrier with a polymer layer having through-holes or blind holes. Holes may be filled with material, such as colored material.
  • the DE 20 2009 011 195 U1 shows a data carrier having a film-like structure comprising at least one polymer film having a plurality of continuous micropores which are distributed over the surface of the film, wherein on one of the surfaces of the porous film, an additional layer of polymer material is applied so that the material the layer at least partially fills the micropores from the side of its arrangement, the depth of filling of the pores being selected taking into account the predetermined amount of data.
  • the filling can be done with one color.
  • a document which is protected by a security feature in the form of a perforation pattern against counterfeiting, the perforation pattern having holes of different sizes.
  • the Perforation pattern represents a passport photo and is introduced by means of laser light in the document.
  • the invention has for its object to provide a method for producing a security document, which allows individualization of an otherwise finished security document blank in such a way that the individualization information is rich in contrast, preferably colored, stored in the security document and difficult to imitate or for a counterfeiter to falsify is.
  • the invention is based on the idea of introducing holes into a substrate of a security document with the aid of laser radiation, and of introducing a colored ink into at least part of these holes by printing technology. This ensures that the information applied by printing is not only arranged on the surface of the document, but at least partially in a depth of the substrate, that is stored in the interior of the substrate. Nevertheless, the information is applied so that it is viewable from the outside.
  • the fact that the preferably color introduced information is placed in the holes this is better protected against any occurring in the ordinary use of the security document attrition or other damage.
  • a method of producing a security document comprising the steps of: providing a substrate; Introducing holes into a surface of the substrate and introducing colored ink by means of a printing process into at least some of the holes.
  • a device for producing a security element which has a laser device for the targeted introduction of holes into a surface of a substrate, which is coupled to a printing device, so that at least some of the holes deliberately introduced into the substrate, preferably colored, ink can be introduced by means of the printing device.
  • Substrate may be, for example, a layer of a card body or a card body made of one or more such layers of a security document.
  • a residue-free removable film is applied or applied to the substrate. This is or is applied before applying the holes. This makes it possible to use larger alignment tolerances with respect to an orientation of a print image and the positions of the holes. Nevertheless, it is ensured that no ink remains on the surface of the substrate next to the holes. Thus, a film to be removed without residue from the surface of the substrate is applied to the surface of the substrate prior to the introduction of the holes.
  • Such a film for example an adhesive film, is also advantageous if other printing processes are to be used and printing of an environment of the holes on the surface is to be omitted.
  • colored information is considered if it causes a color impression in a human observer, if necessary, after an excitation.
  • Information is considered to be multicolored if it causes at least two color impressions which can be differentiated for a viewer, brightness differences not being intended to represent different color impressions.
  • information is considered colorful if it causes more than three different color impressions.
  • at least one color impression is caused by an additive color mixture (in the case of luminescent colors) or a subtractive color mixture (in the case of so-called body colors) from primary colors which span a color space. Black and gray levels are considered a color here.
  • Inks are understood to mean all preparations which can be applied to a substrate by means of a printing process or can be introduced into holes formed in the substrate. Colored inks are thus preparations which comprise colorants which cause a color impression in the printed state in the case of a human observer, if appropriate after an excitation with luminescent colors.
  • Suitable substrates are all materials from which security documents are manufactured.

  • the ink is added to a solvent dissolving the material of the substrate and the substrate is locally dissolved by means of the solvent of the ink in order to promote the diffusion of the colorant in the substrate.
  • the holes are preferably introduced by means of laser radiation. Focused short-pulse lasers can locally introduce such a large amount of energy in a short period of time into transparent substrate material, for example transparent polycarbonate, that it is ablated without discoloring adjacent layers.
  • Anti-counterfeiting security can be increased by forming the holes by irradiating the laser radiation onto or into the substrate from a direction that is different from a surface normal of the surface of the substrate.
  • holes are formed in a preferred embodiment, which are partially concealed by this in a vertical plan view of the surface of the substrate. This means that no clear view of the inner wall surface of the entire hole is possible. Nevertheless, with a transparent substrate material be possible to see the inner surface of the hidden part of the hole in a vertical plan view.

  • At least some of the holes are completely filled by means of the colored ink so that these some holes are filled flat in the finished state. This means that after a possible evaporation of solvents contained in the ink in the holes remains a material which permanently fills the holes and whose surface is flush with the surrounding surface of the substrate.
  • a volume of ink is introduced into the volumes of the holes, so that after completion, a projecting over the surface of the substrate supernatant remains.
  • the colored information can also be felt as a raised relief.

  • an intensity of fluorescence radiation of the holes 15 filled with the ink 20 is markedly increased, since the total amount of ink in the holes is larger than in a print, which only takes place on one surface.
