A kind of processing method of water transfer printing paper

Abstract

The invention relates to a processing method of water transfer printing paper. The steps include: A. Unwinding base paper, coating a bottom coating on one side of the base paper, and drying; B. Coating an intermediate coating on the surface of the bottom coating , drying; C. coating the surface coating on the surface of the intermediate coating, drying; D. steam spraying the other side of the base paper; E. coating the back coating on the other side of the base paper, drying; F. Adjust the state of the base paper by using a drying cylinder device; G. Obtained products after winding, slitting and packaging. The beneficial effects of the present invention are as follows: the step of steam spraying is provided to relax the fibers of the printing paper, and the stress of the previous process is released; 2. The drying cylinder is provided to adjust the state, so that the surface of the printing paper is smooth and the internal stress of processing is eliminated.

Description

technical field [0001] The invention relates to the field of printing, in particular to a processing method for water transfer printing paper. Background technique [0002] With the continuous improvement of people's living standards, in addition to practicality, more attention is paid to aesthetics of the objects used. Therefore, various coating technologies have been released. Gradually, some rigid product shells have been painted with three-dimensional paintings to give objects protection. Beautification and other desired effects create a new and better surrounding environment, thereby enriching people's lives and adding a comfortable view. [0003] The general printing process can only be applied to flat surfaces, and it is difficult to achieve direct printing when there is a concave-convex surface. Therefore, the development of water transfer printing technology has overcome the general traditional printing technology and heat transfer printing, pad printing, screen pri...

AI Technical Summary

Problems solved by technology

[0009] However, during the coating and drying process of the bottom coating and the middle coating, the heating process is repeated twice on the front side of the printing paper, so that the stress difference between the front side and the back side of the paper is relatively large, and due to the In the middle, it is not easy to make the stress distribution of the paper uniform, so the overprinting performance of the water transfer printing paper is unstable, and the printing deformation is large, etc.
