Pattern printing device and pattern printing process thereof

Abstract

The invention discloses a pattern printing device, which comprises a hot pressing and discharge printing mechanism, a printing mechanism and a worktable, wherein the hot pressing and discharge printing mechanism is used for heating the surface of raw materials to be discharge-printed; the printing mechanism is used for printing patterns on the hot-pressed and discharge-printed raw materials and is arranged at a workstation next to the hot pressing and discharge printing mechanism; the worktable is used for supplying the raw materials to the hot pressing and discharge printing mechanism and the printing mechanism and supporting the raw materials. By using the pattern printing device disclosed by the invention, since the hot pressing and discharge printing mechanism is used to fade the surfaces of the raw materials to be in white bottom color and then the patterns are printed on the white bottom color layer by using the printing mechanism, the white bottom color layer is not required to be additionally sprayed and the cost is effectively reduced; since in the discharge printing, additional glue does not need to be sprayed on the surfaces of the raw materials, the thickness of the printed raw materials is not increased and the hand feeling of the raw materials are kept. The invention additionally discloses a pattern printing process, which comprises the steps of (1) coating a fading agent at positions to be printed with the patterns on the surfaces of the raw materials; (2) performing hot pressing and discharge printing on the raw materials coated with the fading agent to discharge-print the surfaces of the raw materials to be in white color; (3) printing the patterns.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing device and a printing process thereof. Background technique [0002] Screen printing is the most widely used T-shirt printing technology. The screen printing technology mainly includes design, printing, printing, printing and drying. Screen printing, simply put, if a T-shirt pattern has three colors of red, yellow, and blue, then three plates need to be printed, one for each color. Screen printing can be mainly divided into: water slurry printing, glue printing, ink printing. [0003] The transitional layering of cloth screen printing is poor, and it cannot be natural and realistic. Later, digital printing gradually appeared. [0004] Simply speaking, the production process of digital printing is to input various digital patterns into the computer through various digital means such as scanning, digital photos, images or computer processing, and then process them thr...

AI Technical Summary

Problems solved by technology

[0010] 1. Generally, digital printing can only be used for white background fabrics, while dark-color bottom fabrics need to be sprayed with white background color first, and then print patterns on the white background color. High, not conducive to promotion;

[0011] 2. The background color of the white background needs to be glued and fixed, resulting in poor air permeability of the fabric, increased thickness, and bad hand feeling;

[0012] 3. Digital printing can only print patterns in a single process, and cannot print other processes through the screen at the same time, and the application range is narrow
