  • Cancellation of micr-readable documents by application of an ink containing magnetic particles
    Patent number: 6031020
    Abstract: The present invention is directed to the deliberate cancellation of MICR-readable documents by applying a penetrating ink through the MICR line of the document wherein the ink contains magnetic particles which disrupt the reading of the MICR line by the MICR reader. The magnetic particles in the ink do not penetrate along with the other ink components, but remain on or near the surface of the document. These extraneous magnetic particles interfere with MICR readers by preventing accurate reading of the encoded MICR characters and cause the MICR reader to reject such a document from normal processing automatically.

  • Tri-component security numbering ink
    Patent number: 5944881
    Abstract: A security ink is provided containing a colored dye, a colored pigment, and a fluorescent pigment. The ink may be printed on a number of security documents such as checks and may be passed through printing devices such as laser printers without the problem of damage to the ink the printed image, or the printer.
