Abstract
Building panels, especially floor panels, and a method of forming embossed in register surfaces with a digital ink head that applies a curable ink on the panel surface or on an upper side of a foil as a coating and forms an ink matrix that is used to create a cavity in the surface by applying a pressure on the ink matrix.
Claims18
A method of forming an embossed surface on a building panel, the method comprising:
- providing a substrate;
- applying a curable ink on an upper part of the substrate, thereby forming an ink matrix on the upper part of the substrate;
- forming a cavity in a surface layer of the building panel by pressing a lower part of the substrate against the surface layer of the building panel, while the ink matrix is located on the upper part of the substrate that does not contact the surface layer of the building panel, thereby forming an embossed surface of the building panel, wherein the lower part of the substrate pressed against the surface layer of the building panel is free of curable ink;
- and
- removing the substrate with the ink matrix from the embossed surface.

A method of forming an embossed surface on a building panel, the method comprising:
- providing a substrate, wherein the substrate is a pressing cylinder or a roller;
- applying a curable ink directly on a surface of the substrate for forming an ink matrix on the surface of the substrate;
- forming a cavity in a surface layer of the building panel by pressing the surface of the substrate and the ink matrix located on the surface of the substrate against the surface layer of the building panel, thereby forming an embossed surface of the building panel;
- removing the substrate from the embossed surface such that the ink matrix is transferred from the surface of the substrate to the embossed surface;
- and
- removing the ink matrix from the embossed surface.
