Method of producing three-dimensional structural surfaces

Method of producing three-dimensional structural surfaces Abstract The invention relates to a method of producing three-dimensional structural surfaces based on synthetic resin-impregnated materials applied to the surface， in particular of wood-based panels. Before the impregnation， at the stage of pattern printing， a mixture is applied to the decor paper， consisting of printing ink， whether with pigment or not， and a swelling agent in the form of microspheres， being encapsulated gas bubbles of sizes ranging from 2pm to 180pm， increasing its volume under the influence of rising temperature， wherein the mixture of the ink and the swelling agent contains from 0.3% to 45% by weight of the swelling agent， and after exiting the printing press and after the impregnation， the decor paper with the formed final pattern with a coded three-dimensional structure is pressed onto the surface， in particular of a wood-based panel， using a heated press plate with any working surface.
