A method that allows to obtain embossings on ultraviolet-coated surfaces of panels and the like or of cladding films and also allows to recondition the surfaces and edges of panels of chipboard or the like in order to prepare them for printing or facing, comprising the steps of: coating the surface to be treated and coupling on the fresh UV coating a release element (5) that is not fully opacified or is transparent, so as to allow UV light to pass, allowing partial or total hardening of the photochemical coating, so that the release element can be removed clean, leaving the intended impression on the surface. Full polymerization of the coating is then performed by subjecting the exposed surface to further irradiation.
L'invention concerne un procédé permettant d'obtenir des gaufrages sur des surfaces à revêtement UV (c'est-à-dire sensibles aux ultraviolets) de panneaux, ou analogues, ou de films de placage et permettant également de reconditionner les surfaces et les tranches de panneaux d'aggloméré, ou analogue, pour les préparer à l'impression ou au parement. Ce procédé consiste à enduire la surface à traiter et à ajouter sur le revêtement UV frais un élément de séparation (5) qui n'est pas entièrement opacifié ou qui est transparent de façon à laisser passer les ultraviolets et occasionner ainsi un durcissement partiel ou total du revêtement photochimique de telle sorte que l'élément de séparation puisse être éliminé, laissant l'impression voulue sur la surface. On effectue ensuite une polymérisation complète du revêtement en soumettant la surface exposée à une nouvelle irradiation.
