  • System and method for producing secure toner-based images
    Patent number: 7220524
    Abstract: A system and a method for printing a secure document that is difficult to forge and readily easy to visually verify are disclosed. The system includes a colorant for printing an image on a surface of a document, a dye for forming a latent version of the image underneath the surface, a substrate, and a migration agent for facilitating the migration of the dye through at least a portion of the substrate. The migration agent may be coated onto a portion of the substrate or embedded within the substrate. An ink may serve as the migration agent, in which case, the ink contains a solute for the dye.

  • Secure imaging toner and methods of forming and using the same
    Patent number: 7220525
    Abstract: A toner for printing documents that are difficult to chemically or physically forge and that are readily easy to visually verify and methods of using and forming the toner are disclosed. The toner includes a colorant for printing an image on a surface of a document and a dye for forming a latent version of the image underneath a surface of a substrate. An image formed using the toner of the invention is readily verified by comparing the colorant-formed image and the dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.
