Abstract
The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating and said surface having, in selected regions, at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions on the first coating, and be produced by a combination of metallic coatings and mechanical or chemical after-treatments. Therefore, for example, a wood pore with a defined structure can be substantially better reproduced, and the optical and haptic properties of the wood composite board produced using the press plates can thus be improved.
