Abstract: A method is provided for laminating a thermoplastic layer to at least a print area of a printed thermoplastic substrate (e.g. a polycarbonate substrate and laminate layer). A printed thermoplastic substrate comprises a print area on which an image (e.g. a portrait) is printed (e.g. by inkjet printing), the print area comprising a pattern of recessed cells separated by bridges. Each cell comprises recessed image receiving surfaces below a nominal surface of the print area for holding the ink of the printed image. The bridges have surface areas above the ink and the surface areas of the bridges comprising enough of the print area to provide lamination bonding areas. Using heat and pressure, a thermoplastic layer is laminated to at least the print area of the thermoplastic substrate to form lamination bonding between the thermoplastic layer and the lamination bonding areas provided by the surface areas of the bridges.

Abstract: A method is provided by the invention for printing surface applied images to a thermoplastic substrate to provide improved durability to the printed image. A thermoplastic substrate comprises in a predetermined area a pattern, preferably a cell pattern, of recessed image receiving surfaces below a nominal surface of the thermoplastic substrate and a pattern of bridges separating the recessed image receiving surfaces, the depths of the recessed image receiving surfaces and the areas of the bridges separating the recessed image receiving surfaces, relative to the areas of the recessed image receiving surfaces, chosen to provide durability to the image after the image has been printed onto the predetermined area. The image may be printed by ink jet printing. To additionally provide security features to the security instrument, latent and hidden images may be formed by latent image recesses and hidden image recesses, respectively, below the nominal surface.
