  • Photocopy resistant document and method of making same
    Patent number: 5601683
    Abstract: A photocopy-resistant document which has a background pattern or logo which is printed with solvent-sensitive, dye based ink and a method of making such a document. The presence of this photocopy-resistant background pattern or logo makes it impossible for a would-be forger of a face-value note such as a bank check to duplicate the original document as a color photocopy. It also makes it impossible for a printing plate to be made based on a photocopy of the document. Besides being photocopy-resistant, the indicia printed with the solvent-sensitive ink are washed away when acetone or bleach solvent is applied to the surface of the document. A fluorescence material can also be added to the solvent-sensitive ink to make the indicia printed with the ink fluorescent under black light.
    Type: Grant
