Abstract: An embossing tool comprised of a pressing plate or endless belt that includes a structured surface, a first gloss level over the full area of the structured surface, and further, different gloss levels in several selected areas of the structured surface. The gloss levels are created by mechanical post-treatment and/or chemical post-treatment. A method for producing the embossing tool is also involved. The structured surface is provided with a first gloss level over the full area and receives further, different gloss levels in several selected areas in further work steps. The gloss levels are created via a mechanical post-treatment and/or chemical post-treatment.

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.

Abstract: The invention relates to a method for producing a surface structure on a pressing tool, in particular a pressing plate (1), endless belt or embossing roller. According to the invention, in order to avoid a lengthy etching process, the surface structure is produced by means of metal layers lying one over the other. For this purpose, at least a one-time application of a mask is performed in order to cover partial regions and at least a one-time application of a metal layer to the non-covered regions (5, 6) is performed in order to construct a surface structure composed of elevations. The two individual method steps are repeated until the desired structure depth has been reached. By means of a final treatment method, the surface can be rounded or provided with a hard chromium layer (7), for example.

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 (6) and said surface having, in selected regions (7, 8, 9, 10, 11), at least one additional metallic coating that has a differing degree of lustre.

Abstract: The invention relates to a composite board (1) having at least one structured surface side, in particular a surface (2) with a wood pore, wherein elevated and lowered regions are formed. In order to obtain improved haptics and visual characteristics, it is provided that the embossing of the surface (2) takes place by way of a pressing plate or endless belt, which has a first gloss level over the full surface area and has been given further different gloss levels in a plurality of selected regions in further working steps, wherein the gloss levels can be produced by a metallic coating, a mechanical and/or chemical post-treatment.
