  • the stamping foil has the advantage that its use during embossing is particularly low maintenance. Femer can their use To simplify the compression with a B ⁇ ndpresse much. Compared with the surfaces machined with metal, structured bands of a belt press, the structures which are produced by the embossing foil according to the invention are particularly uniform and defects do not occur. Furthermore, the continuous, circulating, structured bands of a belt press provide less number of uses of the stamping foil for consistent results in the negative impression. Furthermore, the paper used has the advantage of leaving no damage to the embossing devices, such as press belts and the like.
  • the paper protects the surface of the article against unwanted effects of the embossing device on the surface of the article, For example, the surface gloss is retained in a laminate panel, since the metal belt presses do not act directly on the top layer, usually the so-called overlay.
  • the surface structure of a further applied to the carrier film layer comprises, for example, on the Sufoiie a lacquer applied, in which the desired structures were hineinge Weggt in order then later themselves to be able to form.
