Definitions

  • the invention relates to a method for distinguishing original prints from copies.
  • warning markings that are not visually visible, because they are of the same color and density of the background and are overlaid by other prints or patterns (DE-OS 34 19 859).
  • the warning marks are only visible in the copy.
  • the invention had for its object to provide a security method for the latter purposes of directly printing value stamps on various printing templates, which makes copies of the original prints or forgeries recognizable.
  • This object is achieved by adding substances to the printing medium which, in the original print, produce markings which are invisible to the eye and thus for copying purposes.
  • markings from the invisible substance cover the ink ribbon as lines, grids or patterns and arrive, for. B. with franking or value cancellations, with the imprint on the template.
  • the substances can be sprayed on via nozzles from a special storage container, with lines and screens being generated by means of the printer control.
