Definitions

  • the invention relates to a method for producing and processing an image on a card substrate of an identification card and the identification card according to the preambles of claims 1, 7 and 8.
  • identification documents often have a color image on their surface in order to facilitate and accelerate the identification of the person belonging to this identity card by a controlling person or machine and to prevent the transfer of the identification card.
  • protective films are used to protect against unauthorized modification of such printed color images, which may cover the entire card body including the image components of the color image.
  • protective films increase the manufacturing costs in terms of their material value and the additional mandatory manufacturing step of their application on the surface of the card body.
  • the protective film is subsequently removed again from the card body in order to change, eliminate or replace the color image.
  • such protective films often show signs of wear, which thus do not lead to effective permanent protection against a desired or unwanted change in the color image.
  • a recording medium with colored image information which is present as a value or identity card.
  • the image information is decomposed into a light / dark component and a color component.
  • the light / dark portion is superimposed by the colored image information congruent.
  • One of these components is irreversibly introduced into the recording medium by means of a laser.
  • the black / white portions are preferably baked by means of the laser and superimposed by the color components.
  • this method already fails in the intended illustration of a fair-skinned blond person, since the low or nonexistent black component leads to a very poor imaging quality in terms of resolution and contrast.
  • the present invention is therefore based on the object of providing a method for producing and processing an image on a card substrate of an identification card and an identification card, by means of which a forgery-proof image, preferably colored personal image, on the card with high image quality regardless of black parts of the image to be imaged is possible.
  • An essential point of the invention is that in a method for producing and processing an image on a card substrate of an identification card, the following steps are carried out:
  • Such a method advantageously has the possibility of producing a tamper-proof identification card with the associated color image, irrespective of the degree of the black image components within the color image, even if a protective film is not used on the surface of the card body.
  • the outer shape of a person's head can, for example, be black or white or gray is formed, permanently highlighted as a burned-in line.
  • This leads to a forgery-proof identification card since, although the printed color image in its printing components can be removed from the outside, since it is arranged on the surface of the card substrate, the contours or boundary lines burned beneath the surface of a surface layer applied to the card substrate do not can be removed without destroying the entire card body.
  • the card can be printed by means of an inkjet printer by means of dysublimation, with the color photograph from the outside.
  • the surface layer material is selected such that it appears transparent to laser light of the laser used with its associated wavelength, so that a baking process takes place below the surface layer.
  • the transparent surface layer which may be formed as a separate film, for example, or integrated within the card substrate, is traversed by the laser beam by means of a laser beam tracer and generates the blackened line region below this layer. There is an absorption of the laser beam energy by the underlying material instead, whereby the material thermally decomposes or discolored and thereby the black lines.
  • the step of heating by means of the laser beam at a temperature existing at the heating location should be carried out in such a way that the necessary combustion temperature with respect to a combustion process of the card substrate material to be thermally heated to form black lines is achieved either by correspondingly slow guidance of the laser beam or by corresponding energy irradiation ,
  • a solid-state laser with a wavelength of 1064 nm is used, since such lasers enable a high energy output.
  • card substrates made of a material such as hard PVC can be provided without problems with black lines having an accurate line.
  • Such black lines are not susceptible to etching and the like which are external to the surface of the card substrate.
  • the different color characteristics are preferably determined by a pixel comparison.
  • adjacent color brightness values and color contrast values may be used to determine boundary lines between adjacent image constituents having different color features.
  • the detection and evaluation unit which for example has a camera with associated ejection and evaluation unit, is used.
  • software used.
  • Such a recognition and evaluation unit scans the card substrate or takes a complete picture of the image or photo, in order to detect the data in dependence on the location coordinates with respect to the map body and then to calculate the location coordinates of the resulting boundary lines between the individual image components.
  • These spatial coordinates of the boundary lines are used to displace the displaceable laser unit parallel to the surface plane of the card body in accordance with the boundary line course and thereby to obtain a black line by incidence of a laser beam oriented as perpendicularly as possible to the surface plane to avoid reflections on the surface.
  • a step sequence of the manufacturing process in which first the image is printed on the card substrate and then tracing the boundary lines between see the image components by the laser takes place, in a first step, a calculation of the contours between the image components of the photo, which still is not printed on the card body, then carried out by moving the laser, the formation of the black lines along the determined by means of the location coordinates boundary lines on the card body and finally the color image are printed in a printing process on the surface of the card body.
  • the printing operation is set to the end of the manufacturing process, for example, to obtain a drying process of the printing surface with sufficient time in the identification card in the stored state.

Abstract

L'invention concerne un procédé pour produire et traiter une image sur un substrat de carte d'une carte d'identité. Le procédé selon l'invention comprend les étapes qui consistent : à imprimer une image couleur sur une surface de la carte d'identité au moyen d'une imprimante ; à balayer optiquement la surface de l'image imprimée, et à détecter des composants individuels de l'image imprimée dont les caractéristiques chromatiques diffèrent les unes des autres, à l'aide d'une unité de détection et d'évaluation ; à calculer des coordonnées des lignes limite qui sont disposées entre lesdits composants détectés, et qui représentent les contours des composants, à l'aide d'une unité de calcul, et ; à chauffer linéairement le matériau du substrat de carte, en dessous de la surface d'une couche de surface du substrat de carte, le long des lignes limite, par déplacement d'un laser le long des plans de surface du substrat de carte au moyen des coordonnées calculées. Cette invention concerne en outre une carte d'identité pourvue d'une image couleur.
