Abstract

The invention provides a preparation method of water transfer printing stained paper. The preparation method comprises the following steps that (1) an electronic manuscript is subjected to color separation; (2) a film is manufactured, and the film net hanging precision ranges from 176 lines to 210 lines; (3) a screen is manufactured, and the number of meshes of the screen ranges from 380 to 450; (4) photoresist with the resolution rate being larger than 800 LP / mm is sprayed, and the film is pasted to the screen for exposure; (5) the screen obtained after exposure is immersed into water for 1-2min by being away from light and then is taken out, and the un-exposed part on the screen is washed with water; and (6) a scraping knife with the Vickers hardness ranging from 75 to 80 is adopted forprinting, an angle ranging from 60 degrees to 85 degrees is formed between the scraping knife and the screen, and after printing is completed, drying is carried out, and the paper can be obtained. The preparation method of the water transfer printing stained paper is simple and easy to operate, the effect that net points cannot be seen under the eye level condition of naked eyes can be achieved,and textures and / or patterns of products are clear and attractive.

Description

technical field [0001] The invention belongs to the technical field of decal paper production, and in particular relates to a preparation method of fine decal paper for water transfer printing. Background technique [0002] With the development of the economy and the continuous improvement of consumption levels, people have higher and higher requirements for the aesthetics of daily necessities. At present, the patterns on various utensils are mainly obtained by printing and duplication, but this is not completely suitable for special-shaped or special-required substrates. Water transfer printing technology is a printing method that prints the pattern on the water transfer backing paper and transfers the pattern to the product after soaking in water. With the improvement of people's requirements for product packaging and decoration, the use of water transfer printing is becoming more and more more extensive. The principle of indirect printing and perfect printing effect sol...
