OG exemplary drawing
 
1. A coated panel with a substrate and a decorative top layer forming an upper surface of said coated panel,
wherein the decorative top layer comprises a print and a transparent wearing layer applied thereon,
wherein the coated panel has a lowered edge region at least on one edge,
wherein both the print and the transparent wearing layer extend continuously from on a central area of the coated panel over the lowered edge region,
wherein the transparent wearing layer comprises a base material and a surface layer with a degree of gloss of 10 or less determined by a microstructure of the surface layer itself,
wherein the surface of the lowered edge region is formed essentially by the base material;
wherein the transparent wearing layer has a lower degree of gloss at a location of the lowered edge region than on a central area of the coated panel and/or has a degree of gloss of 10 or less measured according to DIN 67530;
wherein the degree of gloss at the location of the lowered edge region is defined by a microstructure of the base material itself and wherein the lower degree of gloss is obtained because the transparent wearing layer has a rougher surface structure at the location of the lowered edge region than at the location of an overall surface and/or because the transparent wearing layer is compressed at the location of the lowered edge region.
 
16. A coated panel with a substrate and a decorative top layer,
wherein the decorative top layer comprises a print and a transparent wearing layer applied thereon,
wherein the transparent wearing layer comprises, on a surface, a coating or surface layer with a microstructure that has a roughness,
wherein the coated panel has a lowered edge region at least on one edge,
wherein both the print and the transparent wearing layer extend continuously from on a central area of the coated panel over the lowered edge region,
wherein the transparent wearing layer comprises a base material and a surface layer with a degree of gloss of 10 or less determined by the microstructure of the surface layer itself, wherein the surface of the lowered edge region is formed essentially by the base material,
wherein the transparent wearing layer at a location of the lowered edge region is free from the coating or surface layer but has a microstructure with a roughness that differs less than 0.5 μm Ra from a roughness of the microstructure of the surface layer;
wherein a degree of gloss at the location of the lowered edge region is defined by a microstructure of the base material itself.
