EMBOSSING OF COATED SHEETS

摘要

A method for decoration of paper or plastic sheeting by providing a coating (11) and then embossing the coated substrate (10). The coated sheet is heated to soften the coating (11) by use of a heated platen (32) or heated cylinders (21, 22) and infrared heaters (23). The softened sheet surface is then decorated using an embossing member (31) to provide a diffraction pattern or hologram. The embossment pattern has a lesser depth than the surface roughness of the sheet before embossing.
