Abstract

The invention discloses a preparation method of wood grain heat transfer film or heat transfer paper. The method comprises following steps: deepening the engraving of wood grain on a cylindrical gravure roll, wherein the wood grain comprises a wood stab layer and a wood flesh layer; print substrates, ink, scrapers and a cylindrical gravure roll are well prepared; the cylindrical gravure roll is installed on a gravure press; the print substrates are installed on a material storage rack of the gravure press; wood flesh layer ink is poured in the front part of the gravure press by section; wood stab layer ink is poured in the rear part of the gravure press by color section; the ink viscosity, the bellow temperature of the press, and the production speed of the press are well adjusted; sammeld ruck is carried out; finished product is rolled up to finish printing. According to the preparation method of wood grain heat transfer film or heat transfer paper, by means of the printing plate-making technology, the engraving depth of plate roller is enlarged; through toning wood stab layer and wood flesh layer with ink having different colors and different optical haze degree, wood grain transfer paper or transfer film having 3D visual effect and projection wood grain hand feel is produced. The preparation method is simple.

Description

technical field [0001] The invention relates to the field of heat transfer films, and mainly relates to a method for preparing a wood grain heat transfer film or paper. The preparation method can make the transfer pattern have 3D stereoscopic vision and the effect of protruding wood grain. Background technique [0002] At present, although there are many imitation solid wood furniture and board products on the market, most of the surface wood grain patterns are presented by pasting solid wood veneer or using simulated PVC film, and all have certain defects: the former is prone to warping, which affects the service life The latter has the shape of wood grain, but it is difficult to present the texture of wood grain, and the degree of simulation is poor. The traditional wood thorn transfer film cannot simulate the three-dimensional effect of wood grain. At present, the wood thorn with three-dimensional effect can only be produced by UV printing method. The operation is complic...
