FIELD: printing.SUBSTANCE: in the application a valuable and/or counterfeit-proof document is described, with a self-scan protective element comprising luminophore. In different areas of the surface of valuable and/or counterfeit-proof document at least two different luminophores are located, which differ in wavelength of the luminescent emission emitted by them and which form an image. Moreover, each wavelength of the luminescent emission corresponds to one sign, and each area of the surface of valuable and/or counterfeit-proof document corresponds to a position of the sign. As a result, due to the choice of different luminophores in combination with their place of location the first self-scan sequence of signs is formed.EFFECT: invention provides a high degree of protection against forgery of the document, and the simplicity of its manufacturing.15 cl, 4 dwg |
