  • banknote sheet is known, which is first printed completely finished, i. Flat, solid, gravure and high pressure, offset, screen printing, intaglio and numbering, and then laminated on both sides with a foil.
  • the disadvantage here is that in case of errors in the preparation of a banknote, the later committee of the relevant
  • Banknote the numbering of the banknote series is no longer continuous because the banknote is missing with the corresponding number.
  • a continuous numbering of a banknote series is required by many customers.

  • a coating is applied to the security paper between the protective layer and the side of the security paper to which this protective layer is applied, which is changed contactlessly through the protective layer by electromagnetic radiation in a subsequent step, so that an individual information is transmitted. is written on in the coating.
  • the coating can be applied over the whole area to or on only a portion of the surface of the security paper.

  • a particular advantage of the invention is thus that the internal individualization is protected by the protective layer against external influences in circulation. Furthermore, the individualization can be inscribed into the coating through the protective layer without destruction.
  • the electromagnetic radiation is generated by a laser.
  • the protective layer is a laminated, laminated or extruded film or varnish.
  • a film is applied as a protective layer on the front and / or back of the security or a coating in the form of a lacquer layer, which is printed by a printing process on the front and / or back of the security.
