摘要
The invention relates to a method of manufacturing an imprinted effect in a plastic film, characterized by the following steps: a) applying a hardenable mixture of lacquer and solvent subject to volumetric shrinkage in liquid form to a localized area of the plastic film, whereby the plastic film surface is for all practical purposes made insoluble by the solvent; b) drying the lacquer-solvent material; c) hardening the lacquer to a lacquer-laminate layer that is completely bound to a localized area of the surface; and d) allowing the lacquer-laminate layer to shrink, with a simultaneous tightening of the laminated plastic film below the lacquer-laminate layer without formation of wrinkles.
