Definitions

  • the invention relates to a method for applying a decoration and a surface structure to a carrier material and a device suitable for this purpose.
  • a carrier material or at least one decorative paper is printed with a decoration and a file for the surface structure is created from the digital image data of the decoration.
  • at least one layer of a resin is applied to the printed carrier material or to at least one overlay, the distribution of the resin being specified by the file for the surface structure and thus depending on the printed decoration.
  • the at least one resin layer is then pressed with the carrier material using a structured press sheet or the at least one overlay, the at least one decorative paper and a carrier material are pressed with a structured press sheet. In both cases, the structure of the pressed sheet is specified by the surface structure file and is therefore also dependent on the printed decor.
  • a surface structure is formed on the carrier material, which is synchronous with the applied decoration.
  • the wood-based panels or wood-plastic panels can also be printed directly with a decor.
  • Several liquid thermosetting resin layers (usually melamine resins) are then usually applied to the decor applied by direct printing, which in turn can contain abrasion-resistant particles to increase wear resistance.
  • an essential quality feature is the pleasing surface structure. This should not only be synchronous with the decor, but also be as accurate a replication as possible of the underlying template from nature or another product in terms of the structural depths of the structure of the decor. What is most important is that the replica has an optical and tactile impression that is as true to the original as possible. It is therefore desirable that the embossed structure is coordinated with the printed decor and thus a decor-synchronous structure or a synchronous pore is formed.
