A process for the manufacture of a decorative surface element, which element comprises a base layer, a decor and a wear layer of a UV or electron beam curing lacquer. One or more structured surfaces, forming embossing surfaces of one or more rollers or moulds, are positioned on top of the decorative lacquered surface, possibly after having cured the lacquer to a desired viscosity, and are continuously or discontinuously pressed on to this. The lacquer will be provided with a surface structure which enhances the decorative effect of the decor. The wear layer is then completely cured.

The invention claimed is: 1. A process for the manufacture of a decorative surface element, which element comprises a base layer, a décor and a wear layer of a UV or electron beam curing lacquer, said process comprising the steps of: positioning one or more structured rollers or molds on top of the lacquer, the one or more rollers or molds provided with embossing surfaces, pressing said one or more rollers or molds into said lacquer, whereby the lacquer will be provided with a surface structure, thereby enhancing the decorative effect of the décor, and thereafter completely curing the wear layer by applying a UV or electron beam, wherein one or more glazing rollers is pressed towards the surface structured wear layer before the complete curing stage. 2. A process according to claim 1, wherein the structured rollers are heated to a surface temperature (ST) above 40° C. 3. A process according to claim 1, wherein the glazing rollers are heated to a surface temperature (ST) above 30° C. 4. A process according to claim 1, wherein a thin top coat is applied on top of the structured wear layer after the glazing stage. 5. A process according to claim 1, wherein a thin top coat is applied on top of the structured wear layer before the glazing stage and that the top coat is partially cured before the glazing. 6. A process according to claim 1, wherein each glazing roller is provided with a counter stay roller between which the surface element is passed. 7. A process according to claim 6, wherein the surface element has a thickness T and that the distance between each glazing roller and corresponding counter stay is set in the range T minus 0.7 mm-1.2 mm. 8. A process according to claim 7, wherein the pressure between each glazing roller and its corresponding counter stay is 0.1-10 Bar. 9. The process according to claim 7, wherein the distance between each structured roller and corresponding counter stay is in the range T minus 0.7 mm-0.9 mm. 10. The process according to claim 7, wherein the pressure between each glazing roller and its corresponding counter stay (P) is 65-100 Bar. 11. The process according to claim 2, wherein the structured rollers are heated to a surface temperature (ST) in the range of 50° C.-150° C. 12. A process according to claim 3, wherein the glazing rollers are heated to a surface temperature (ST) in the range of 35° C.-100° C.
