Latest Patents

Walter's latest patents include a process for the manufacture of identity cards. This method involves electrophotographically reproducing identity information on a multilayer card core material, followed by laminating protective film on both sides. The core material can consist of several layers with additional security markings. Notably, a relief grid image or hologram can be integrated into the card core before lamination. Another patent discloses an identity card made up of multiple layers, where the cover layers are highly transparent films, and the core layers have varying transparency due to added pigments. One core layer contains directly readable information above a security print, while another features additional security markings, such as a guilloche print or magnetic tape. All layers are made of polymers that fuse together to create a monolithic laminate without interfaces that allow for separation.
