A security feature for an identification document and method for making it provide layers of security, including, for example, tamper evidence, optically variable effects, and personalized information that links the security information to the document and its bearer. The feature is made by printing a first material representing first information on a core layer of the document. This first material at least partially overlaps the core layer. One example is Xerographic printing of information about the ID document applicant and the applicant's photo. The process also applies a second material representing second information adjacent to the first material. One example is ink jet printing of personal information with a UV curable ink in the form of a relief pattern on the core layer. Finally, the process applies a laminate layer over the core layer. The laminate layer covers the first and second materials. The first and second materials adhere differently to the laminate and core layers such that removal of the laminate layer from the core layer causes a separation of the first and second materials. The relief pattern is made to give the document a tactile feel as well as create optically variable effects.

What is claimed is: 1. A method of making an identification document comprising:applying a first material representing first information on a core layer of the document, the first material at least partially overlapping the core layer;applying a second material representing second information at least partially adjacent to the first material;applying a laminate layer over the core layer, the laminate layer covering the first and second materials, wherein the first and second materials adhere differently to the laminate and core layers such that removal of the laminate layer from the core layer causes a separation of the first and second materials; wherein the second material represents the second information in a relief pattern having a varying surface height relative to a surface of the core such that the document has a tactile feel.
