After the pretreatment of the wood material of graphic representation is taken that had been preliminarily obtained by the computer method, points are applied on the image on a heat-resistant two-layer paper with a subsequent hot pressing with an effort of 60-90 kg/sq.cm and a delay of 125, and the back layer is removed from the two-layer paper with a subsequent cooling down.

EFFECT: enhanced form stability of the wood material with the applied pattern, provided ecologically pure situation at production.

FIELD: formation of covering with selectively formed embossment.

SUBSTANCE: method involves applying plastic layer containing print ink comprising photoinitiator onto substrate; providing gelling and softening of non-hardened coating; softening hardening coating on plastic layer, which had been gelled; providing mechanical embossment of softened hardened coating; activating photoinitiator and hardening said coating of portions on top of indicated print ink; heating for fusing of hardened coating and plastic layer; activating hardened photoinitiator of hardened coating for hardening of said coating on portions free of print ink.

EFFECT: increased efficiency in creating of surface texture effect by providing relatively high embossment depth.

FIELD: construction industry; methods of application on the walls and ceilings of the decorative coatings.

SUBSTANCE: the invention is pertaining to the methods of application of the decorative materials on the surfaces for the purpose of decoration and may be used, in particular, at production of the decorative wall, ceiling coatings or the wall-papers. The method of production of the decorative images provides, that the decorative particles at least by one airflow are applied on the fresh layer of the binding agent earlier applied on the face surface of the material, and conduct drying of the surface. Simultaneously with this application they remove the non-consolidated on the binding particles using at least one suction airflow. The technical result of the invention is the increased effectiveness of the process of production of the decorative image on the material, the increased productivity and the improved quality of the coating.

EFFECT: the invention ensures the increased effectiveness of the process of production of the decorative image on the material, the increased productivity and the improved quality of the coating.
