Abstract

The invention relates to a printing method of three-dimensional braille bumps. The printing method comprises steps as follows: S1, a printing screen is coated with 250-350 mu m of emulsion with a mask-making technology according to drawings and documents of customers, and the emulsion which is not exposed is washed off after exposure; S2, the prepared printing screen is utilized for printing the three-dimensional braille bumps, the S2 comprises steps as follows: S21, a single-sided adhesive tape is flatly attached to the area, close to the edge of printing content, of the printing screen; S22, an automatic web printer is adopted for printing the three-dimensional braille bumps on a base material and drying the three-dimensional braille bumps; S23, the base material is subjected to processing forming after printing, and manufacture of a product is finished. With the adoption of the printing method of the three-dimensional braille bumps, height of the three-dimensional braille bumps is greatly increased.

Description

technical field [0001] The invention relates to a printing process, more specifically, to a printing method of three-dimensional Braille embossed dots. Background technique [0002] Traditional three-dimensional Braille bumps are usually realized through two processes. One of the processes is to use the characteristics of the convex ink itself combined with the low-mesh screen to achieve a relatively thick ink layer thickness through screen printing to achieve the effect of three-dimensional Braille bumps. However, due to the limitations of the process, this three-dimensional Braille bump printing technology has the following problems: the low mesh causes serious jagged edges of the printed bumps, the edge effect is rough, and the printing effect is not exquisite and smooth; due to the leveling of the ink itself, printing will produce orange. The phenomenon of skin or water marks, the height of the three-dimensional Braille bumps is not obvious enough, the touch is not stro...
