Abstract
A thermal transfer printing process for making identification cards is provided. The process involves printing indicia onto a dye-receptive surface of a card substrate. A metallic dye is applied in precise registration with selected print indicia to form a metallic border along the edges of the indicia. The invention also includes identification cards produced by this process. The process can be used to produce cards such as licenses, employee badges, student cards, bank cards, and the like having unique security features.
