Abstract

The invention provides a water transfer printing process. The water transfer printing process comprises the following steps that S1, image-text layer printing is conducted, specifically, UV printing ink which does not contain a light curing agent is printed on a water transfer printing thin film, so that an image-text layer is formed; S2, image-text layer activating is conducted, specifically, the water surface of a transfer printing water tank is horizontally paved with the water transfer printing thin film, and an activating agent and a light curing agent are uniformly sprayed on the surface of the image-text layer; S3, water transfer printing is conducted, specifically, a product needing to be subjected to water transfer printing is gradually attached to the water transfer printing thin film, and the image-text layer is slowly transferred to the surface of the product; S4, washing is conducted, specifically, residual thin film bodies on the product are removed, and floating layers on the surface of the product are washed with clear water; S5, drying is conducted, specifically, ultraviolet rays are shone onto the product, and curing and drying are conducted; S6, paint spraying is conducted; and S7, drying is conducted. According to the water transfer printing process provided by the invention, the UV printing ink can be transferred to the product, and a variety of images and texts can be printed on the product and are environmentally friendly and not prone to disengaging.

Description

technical field [0001] The invention relates to a water transfer printing process and belongs to the technical field of printing. Background technique [0002] With the improvement of people's living standards, the pursuit of beauty is becoming more and more intense. There are more and more phenomena of engraving or printing and dyeing pattern graphics on some plastic or glass products. In the prior art, there are also artificial spraying. Patterns are printed and dyed on plastic products, but the patterns sprayed in this way are not very delicate, uneven, and easy to fall off and be damaged. Contents of the invention [0003] Based on the above deficiencies, the technical problem to be solved by the present invention is to provide a water transfer printing process, which can transfer various pictures and texts to the product, and can print a variety of colorful and exquisite pictures and texts on the product. And it is not easy to fall off, the quality is good, and the p...
