System og fremgangsmåte for overflatebehandling av trefiberplater

摘要

The present invention relates to a method for surface treatment of a machined fiber board (1) having a non-machined main surface (20) and machined sections (2) with pores or rough surfaces. The method includes at least one first step of applying at least one layer of a UV-curable primer (30a) of a type that must be subject to at least one dedicated curing step in order to cure. The invention further includes at least one step of applying a separate layer of a UV-curable primer (30d) and printing a decoration with a UV-curable printer ink (31) onto the primed surface using an ink-jet printing unit. The layer of UV-curable primer (30d) is at least partly uncured during said printing with a UV-curable printer ink (31). The UV-curable primer (30d) and UV-curable printer ink (31) are then cured in a UV curing unit through irradiation with ultraviolet light in a curing step common for the UV-curable primer (30d) and UV-curable printer ink (31). Also described is a method of producing wall or ceiling boards as well as a system for surface treatment of machined fiber boards.
