摘要 PCT No. PCT/EP91/02304 Sec. 371 Date May 24, 1993 Sec. 102(e) Date May 24, 1993 PCT Filed Nov. 28, 1991 PCT Pub. No. WO92/19461 PCT Pub. Date Nov. 12, 1992.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.
