Method for producing a decorative wall- or floor panel

A method for producing a decorated wall or floor panel, comprising the method steps:

• a) providing a melted polymer mass;
• b) extruding the melted polymer mass through a die;
• c) finish-sizing the melted polymer mass to form a carrier plate by means of an assembly of a plurality of rotatable rollers, wherein the individual rollers are arranged one behind the other and each individual roller forms with adjacent rollers at least one finish-sizing nip through which the melted polymer mass is passed, wherein the finish-sizing nip heights are variably adjustable by a horizontal and/or vertical movement of individual rollers during the production process;
• d) applying a decoration reproducing a decoration template onto at least one sub-region of the at least partially finish-sized carrier;
• and
• e) applying a protective coating to at least a sub-region of the decoration, wherein the finish-sizing in method step c) is carried out by use of at least one main roller pair consisting of two rollers with a larger diameter and at least three finish-sizing rollers arranged one behind the other with a smaller diameter compared to that of the main roller pair, wherein the height of the finish-sizing nip of the main roller pair HH differs from the heights of the finish-sizing nips of the finish-sizing rollers HK by greater than or equal to 10% and less than or equal to 50%, and wherein the height of the last and/or the penultimate finish-sizing nip is selected such that the carrier is compressed in its height by a factor of less than or equal to 10% and greater than or equal to 3%.
