Processing method of water transfer printing paper

Abstract

The invention relates to a processing method of a water transfer printing paper. The processing method comprises following steps: A, base paper is unwinded, and one surface of the base paper is coated with a backing coat, and is dried; B, the surface of the backing coat is coated with an intermediate coat, and is dried; C, the surface of the intermediate coat is coated with a surface coat, and is dried; D, the other surface of the base paper is subjected to steam spraying; E, the other surface of the base paper is coated with a back coating, and is dried; F, the base layer is subjected to state adjusting using a drying cylinder; and G, the base paper is winded, cut, and packaged so as to obtain a finished product. Beneficial effects are that: the processing method comprises the step of steam spraying, so that fiber of the obtained water transfer printing paper is loosen, and stress of a former process is released; and the processing method comprises the step of drying cylinder state adjusting, so that the surface of the water transfer printing paper is flat, and processing internal stress 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.
