Definitions

  • the invention relates to methods for producing a value document and to a value document which has a translucent substrate with a front side and a rear side, wherein at least one first information is arranged on the front side and at least one second information on the rear side, wherein the at least one second information is arranged in the Passer is arranged to the at least one first information.
  • paints or coatings are ablated or removed by means of laser beams or modified in their structure or visibility when they show absorption in the wavelength range of the laser radiation.
  • the super-simulcast printing machine is prior art, with which it is possible to realize a multicolor front-side printing adapted to the backside printing, since in this machine, the printing of all colors on the front and back side of the substrate takes place simultaneously.
  • the substrate is guided between two blanket cylinders, each of these blanket cylinder simultaneously performs the task of a counter-pressure cylinder for the opposite color transfer cylinder.
  • other printing machines meet the requirement, if the principle "blanket to blanket" is used.
  • a high-pressure, Toray- (also called water-based effect print) or offset printing plate is inked by means of inking rollers and the subject of the printing plate on the blanket cylinder (in web presses, the blanket cylinder may also be a rubber roller) transmitted.
  • Toray- also called water-based effect print
  • offset printing plate is inked by means of inking rollers and the subject of the printing plate on the blanket cylinder (in web presses, the blanket cylinder may also be a rubber roller) transmitted.
  • Inks containing effect pigments are also referred to as effect colors.
  • the printing of these effect pigments on the substrate is usually done with a separate printing machine, usually in gravure, flexo or screen printing, in order to achieve an optimum optical effect.
  • This is due, for example, to the particular size of the effect pigments, the shape (eg platelet-shaped) and the need for a plane-parallel orientation of the pigments with respect to the surface of the substrate.
  • the pressure with a separate printing machine however, has the disadvantage that due to a new plant of the substrate and possible further mechanical transfer inevitably leads to Passerschwankache between the prints produced with different printing processes.
  • the register variations can vary depending on the quality of the press and the substrate (flatness, dimensional stability), substrate size, active drying The color (UV dryer, hot air / IR dryer), etc. are a few millimeters and are therefore also recognizable to laymen.
  • effect colors are printed on both the front and the back side of a substrate, then the effect colors are usually applied in different printing steps, which leads to a further increase in register variations. This passer problem arises even when film elements and printed images are applied to the substrate with different methods and different machines.
  • the invention is therefore the object of developing a generic method for producing a value document and the generic value document such that the disadvantages of the prior art is eliminated and the protection against counterfeiting is further increased.
  • a translucent substrate is first provided which has a front side and a rear side. Subsequently, at least one first information is applied to the front side of the substrate and at least one second information is applied to the rear side of the substrate, wherein the at least one second information is arranged in register with the at least one first information. Subsequently, at least one third information is applied to the front side and / or rear side of the substrate, wherein the at least one third information is arranged at least partially over the at least one first information and / or second information. In the last invention In the method step, a register is produced between the at least one third information and the at least one first information and / or second information.

  • Translucency in the sense of this invention means that an object, such as the substrate, can pass incident light only to a certain extent. If light strikes one side of the object, a certain portion of the light is transmitted to the other side of the object and exits there again. The greater the percentage of transmitted light relative to the incident light, the more translucent the object is.
  • a translucent object is neither transparent nor opaque in the sense of this invention.
  • An object is said to be transparent if the percentage of light passing through the object with respect to the light incident on the object is at least 90%, i. The object allows the incident light to pass through almost unimpaired, as in a window or opening.
