Abstract
A process for preventing the counterfeiting of valuable documents through use of photography, photocopying techniques, or other methods of counterfeiting. The process includes laminating an extremely thin metallic film to the substrate of the valuable document before the document is printed with the area of the metallic film being small in comparison to the area of the document. The metallic film can be located anywhere on the face of the document and a 'latent image' is embossed on the metallic film when the document is printed. Embossing the latent image on the metallic film, rather than on the document substrate, provides many advantages not possible in the prior art. A photocopy of a document containing the embossed metallic film does not include the latent image and a color photocopy will be different in color than the original document. Therefore, a lay observer can readily differentiate between a genuine document and a counterfeit document.
