SYSTEM FOR PRODUCING SECURE TONER-BASED IMAGES AND METHODS OF FORMING AND USING THE SAME |
摘要 |
A system and method for printing documents that are difficult to forge and that are easy to visually verify are disclosed. The system 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 the surface and a substrate that includes a migration agent for facilitating the migration of the dye through at least a portion of the substrate. The migration-enhancing agent may be coated onto a portion of the substrate or embedded within the substrate. |
