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 mirgration-enhancing agent may be coated onto a portion of the substrate or embedded within the substrate.
L'invention concerne un système et un procédé d'impression de documents qui sont difficiles à contrefaire et faciles à vérifier visuellement. Ce système comprend une matière colorante pour imprimer une image sur la surface d'un document, et une teinture pour former une version latente de l'image sous la surface, et un substrat qui comprend un agent de migration pour faciliter la migration de la teinture dans au moins une partie du substrat. L'agent améliorant la migration peut recouvrir une partie du substrat ou être encastré dans ce dernier.
