Abstract: The disclosure relates to a method for finishing a supplied building panel made of a wood material, in particular MDF or HDF, with an upper side and a lower side, wherein, in a first embossing step, a relief is embossed at least into the upper side as first strip-shaped depressions with two opposing side walls, a bottom wall connecting said side walls and a depth (T), and subsequently a decorative pattern (3) is printed on the embossed upper side of the building panel, and the decorative pattern is then sealed by applying an abrasion-resistant layer (4). According to the invention, additional depressions extending at an angle (α) transversely to the first depressions are embossed, and the large-format supplied building panel is divided into individual panels by carrying out a saw cut in and along each of the depressions.

Abstract: The disclosure relates to a method for finishing a panel, the method includes a) a relief embossed into the upper side in the form of at least one strip-shaped depression with a depth (T), b) a decorative paper applied to the upper side, c) an overlay paper applied to the decorative paper as an abrasion-resistant layer, d) the lower side provided with a backing layer, e) the structure pressed at a high pressure and temperature, and f) during the pressing, at least one strip-shaped depression is again embossed in a second embossing without changing the depth (T). Also, the upper side features a press skin that has a thickness of 0.3 to 0.5 mm, the bulk density of the panel in a top layer is between 950 and 1,000 kg/m3, and an aqueous melamine resin is applied to the upper side as a tempering agent before or after embossing.
