Patent ID: 8840971

Claim:
A method for manufacturing coated panels of the type including at least a substrate and a top layer with a motif, the top layer provided on the substrate, the method comprising: providing a synthetic material layer on the substrate; providing a relief on the surface of the synthetic material layer; wherein the relief shows a pattern of at least one of recesses and protrusions; wherein the pattern is at least partially determined by using a light-projection technique; wherein the synthetic material layer is a transparent or translucent material layer provided above the motif; and wherein the synthetic material layer includes at least a lower synthetic material layer situated closest to the motif that is hardened over essentially the entire surface of the panel, and an upper synthetic material layer situated farthest from the motif that is subjected to the light-projection technique to obtain local, selective hardening over at least 80% of the surface of the upper synthetic material layer; and using a mechanical erosion technique to remove parts of the surface of the upper synthetic material layer that are not exposed to the light-projection technique to form the recesses, such that the lower synthetic material layer exists below the recesses.
