Three-dimensional concave-convex grain printing process

Abstract

The invention relates to a three-dimensional concave-convex grain printing process, which comprises the following steps that S1, according to requirements, a three-dimensional concave-convex grain drawing file is designed; S2, a first flexographic plate and a second flexographic plate corresponding to the three-dimensional concave-convex grain drawing file are output through automatic plate discharging equipment; S3, the first flexographic plate is pasted on a first hard plate for forming a production mother plate; S4, the second flexographic plate is pasted on a second hard plate for forming a production bottom plate; S5, three-dimensional concave-convex grain semi-finished products are produced by utilizing the production mother plate through a UV (ultraviolet) transfer printing process; S6, the three-dimensional concave-convex grain semi-finished products are pasted and fixed with the production bottom plate, and colors are printed on the three-dimensional concave-convex grain semi-finished products; S7, processing forming is carried out, and finished products are formed. The three-dimensional concave-convex grain printing process has the advantages that a better printing effect can be achieved, and the appearance quality of the three-dimensional concave-convex grains is improved.

Description

technical field [0001] The invention relates to a printing process, more specifically, to a three-dimensional concave-convex printing process. Background technique [0002] With the advancement of printing technology, there are already a variety of printing effects that can be applied to various products. Three-dimensional embossed printing technology is widely used because of its good visual effect and suitable for touch, such as numbers on mobile phone buttons. The traditional three-dimensional embossing printing process is mostly realized by two methods. One of the printing methods is to use the characteristics of the ink itself, use a low-mesh screen, and form a thicker ink layer through screen printing to achieve a three-dimensional convex effect. Due to the limitations of the process, this printing technology has the following problems: the low mesh causes serious jagged edges of the printed pattern or text, and the edge effect is rough, and the final printing effect...
