Abstract: For improved quality and use characteristics, before matting, a fine, randomly oriented sub-structure is applied to the press surface of an embossing surface of an embossing tool for embossing the surface of press-formed laminates or the like. The sub-structure is preferably so fine that, after matting, it is no longer recognizable as such. The matting is produced by either mat chromium plating or by sandblasting and subsequent mat chromium plating. The sub-structure is formed in a one- or multiple-step etching process.

Abstract: A working duplicate of an endless master band having a pattern impressed on its surface for use in the production of laminated boards is produced by first making a polyurethane cast of the impressed pattern in the form of an endless, flexible plastic band. A metal layer is galvanically deposited over the pattern on the plastic band to form a galvanic band which functions as a working duplicate after the plastic band has been peeled off. The resultant galvanic band is an exact duplicate of the original master band and is utilized in a press for impressing the pattern on the surface of laminated boards.

Abstract: Large-format embossing tools for applying a given contour to synthetic-resin plates, sheets or foils, e.g. to produce a leather-like or wood-like pattern therein, are produced by printing onto the plates the predetermined pattern in an etch-resist and then repeating the process with a different pattern so that portions of the tool, e.g. an embossing plate for multideck presses, are etched more and less deeply.
