During the water transfer printing process, take the water transfer printing paper and gently bring it close to the substrate surface. Use the scraper pressure to transfer the text, allowing the moisture to be squeezed out, keeping the text flatly placed at the designated position, and allowing it to dry naturally. For water transfer printing of the extractive water transfer printing paper, it dries naturally and is dried in an oven, then the temperature above 100℃ is set for drying to enhance the graphic durability. Since the extractive water transfer paper has a protective coating on the surface, it needs to be protected to avoid spraying. However, the surface of the water transfer printing paper does not have a protective layer, and after natural drying, it is sprayed with petroleum processing, and then UV varnish is applied and cured by a curing machine. When spraying varnish, it is necessary to pay attention to preventing dust on the surface, as it will have a significant impact on the appearance of the product. The thickness of the coating must be controlled to achieve the adjusted light crude oil viscosity and spray volume, and excessive spraying is likely to cause a decrease in uniformity.

For the transfer of the base material, screen printing is adopted. The coating thickness is also an effective protective measure, which can achieve large-scale glazing. The water transfer printing processing technology involves water transfer printing process, water transfer printing paper, paper soaking, pattern transfer, drying and product production. 1 Water transfer printing paper. For computer processing, after the patterned film is used for the output of the printing plate, then the colored pattern printing is carried out on the water transfer printing original paper (through untreated special processing paper), and the printing cover ink is required. The other method is to directly print the water transfer printing original paper and the water transfer pattern using a color laser printer.
