Abstract

See full text

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.
