Abstract
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.

A method for producing an imprinted effect in a plastic film, comprising the following manufacturing steps:
- a) applying to a localized surface area of the plastic film that is to receive the impression effect, a mixture of lacquer and solvent in liquid form which is hardenable with volumetric shrinkage, wherein the plastic film surface is made substantially insoluble by the solvent;
- b) drying the lacquer-solvent mixture;
- and
- c) allowing the lacquer to harden and shrink and form a lacquer-laminate layer that is completely bound to the localized surface area with a simultaneous tightening of the laminated plastic film below the lacquer-laminate layer without the formation of wrinkles.
