Printing process for wallpaper

Abstract

The invention discloses a printing process for wallpaper. The printing process comprises the following steps that (1) a rotary screen print plate and a form of intaglio printing are manufactured; (2) paste is prepared and the viscosity of water-based ink is adjusted; (3) the surface of a printing stock is smeared with the paste through the rotary screen print plate on rotary screen print equipment, so that required patterns are formed; (4) the printing stock with the patterns is fed into a drying oven to be dried; (5) The dried printing stock with the patterns is fed into intaglio printing equipment, and the area, with the patterns, of the printing stock is colored with the standby water-based ink through the form of intaglio printing; (6) the colored printing stock is fed into the drying oven to be dried; and (7) the dried printing stock is press-rolled through a compression roller to form a locally-embossed product. According to the printing process for the wallpaper, non-woven bottom paper is smeared with the specially-made paste to form the required patterns according to patterns on the rotary screen print plate, the locally-embossed product is formed through coloring by the form of intaglio printing, heating by the drying oven and press-rolling by the compression roller, the rich patterns are fine and smooth with fine workmanship and diverse colors, raw materials are guaranteed, and the printing process is safe and environmentally friendly.

Description

technical field

[0001] The invention belongs to the field of wallpaper production, and in particular relates to a wallpaper printing process. Background technique

[0002] Gravure printing is to directly imprint the ink contained in the gravure pits onto the substrate. The shade level of the printed picture is determined by the size and depth of the pits. If the pits are deeper, the ink contained is more. The ink layer left on the substrate after embossing is thicker; on the contrary, if the pit is shallower, the amount of ink contained is less, and the ink layer left on the substrate after embossing is thinner.

[0003] Rotary screen printing transfers the ink to the substrate during the continuous high-speed rotation of the rotary screen through the built-in scraper and automatic ink supply system.

[0004] Gravure printing and rotary screen printing are two common methods of printing wallpaper at present. The embossed wallpaper produced by these two methods is not fine a...
