Abstract:
The invention relates to identification documents, and in particular to providing optically variable personalized data to identification documents. In one implementation, we provide an identification document comprising a document layer and a first indicium. The document layer comprises a material capable of being printed by a thermally transferable optically variable ink. The first indicium is printed on the document layer and comprises personalized data and printed to the document layer by a thermally transferred optically variable ink. The first indicium may be printed to the document layer by disposing a thermally transferable optically variable ink in a mass transfer panel of a printer ribbon adapted for use in a dye diffusion thermal transfer printer, and printing the first indicium as part of a mass transfer printing process. The thermally transferred optically variable ink can be selected and printed such that the first indicium has at least one of a luster, shine, sheen, pearlescent appearance, iridescent appearance, and mirror-like appearance. This technology enables the creation of a halftone “mirror image” over a color ghost image to achieve a layered and linked multiple personalization scheme of ID documents.
