The colour pattern (6, 7) is applied to a temporary substrate (10) in the form of a release paper by generating high contact pressure between the printing surface and the printed substrate using an intaglio or letterpress printing method. A deposit (11) consisting of a foamable unfoamed resin composition is applied to the temporary substrate (10) on top of the colour pattern (6, 7) by a screen printing process. The colour and relief or embossed pattern- forming element are then transferred from the temporary substrate (10) to a substrate (2) intended to form part of the plastic web, under heat and pressure. Heat is again applied to cause the resin to foam and provide the relief or embossed surface. Substrate (2) is preferably coated with a uniform layer (12) of foamable resin. <IMAGE> |
