A web processing system which includes two rollers configured to rotate at the same phase while being in contact with a web which continuously exists along a movement passage and a suppressing mechanism for suppressing a tension variation of the web between the two rollers.

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. The method is characterized in that 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 2 pm to 180 pm, 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.

In an example, a rotogravure printer roller is described. The printer roller (300) comprises a contact surface formed from a plurality of adjacent roller sections (302, 304). The roller sections are constructed and arranged to be removably assembled to form the roller.

A printing device includes a base, a transfer roller, a transfer portion and at least one image collector. The transfer roller includes a rotating shaft and a cylinder body. The transfer portion is disposed on an outer circumferential surface of the cylinder body. The base is configured to allow a printing plate and a substrate to be transferred to be provided thereon, and drive the printing plate or the substrate to be transferred to move, so that the printing plate or the substrate to be transferred comes in contact with the transfer portion disposed on the cylinder body, and moves synchronously with the cylinder body. The transfer portion is configured to allow a transfer pattern to be formed thereon. The image collector is disposed on the cylinder body or the base, and is configured to collect a position of the transfer pattern transferred onto the substrate to be transferred.

A gravure printing plate includes a convex portion and two or more polygonal cells partitioned by the convex portion, and including at least one protruding portion disposed at an edge of each of the at least two polygonal cells and extending toward a central portion of the corresponding cell therefrom.
