A method and apparatus for producing laminated plastic cards, which carry printed matter protected by an overlying layer of transparent plastic material. The picture is formed by conventional laser printing means on a substrate constituted by a plastic material that is sensitive to the combined application of heat and pressure, but is only partially set by radiant heat; thereafter a transparent coating film or sheet is juxtaposed to the printed face of the substrate, and optionally another such film is juxtaposed to its rear face, and the substrate is bound to the film or films by the application of pressure and heat to bind them together.

[ What is claimed is:] [1.] Process for the production of laminated plastic cards,comprising a thermo-mechanically sensitive substrate having a graphic subject matter printed thereon, which comprises;(1) providing a set of digital instructions, which defines the graphic subject matter;(2) depositing, by conventional laser printer operations, printing colors on said thermo-mechanically sensitive plastic substrate to form said graphic subject matter;(3) only partially setting said graphic subject matter by radiant heat;(4) juxtaposing to said substrate, carrying said graphic subject matter, at least a coating film on the printed face thereof; and(5) bonding said substrate and said face coating film.
