Problems solved by technology

[0003] The number of printing editions has a great influence on the effect of the mobile phone panel. The more printing editions, the thicker the thickness of the ink on the panel, the better the shading performance, and the more convenient the control of the color, but the effect on the entire panel The thickness is not easy to control, and the more printing times, the higher the cost, the lower the yield of the product, and too few printing times, although the thickness of the ink will be reduced and the cost will be reduced, but the products produced in this way will be shading Poor performance, bad color control
[0004] Chinese patent application number 201210565141.9, a preparation method of a white panel, discloses a printing method of a white panel, which reduces the thickness of the panel ink through four-pass printing, and eliminates the generation of film after the expansion and overlapping of individual version windows and button areas The difference in thickness and height can easily cause key ghosting and poor defoaming in the CG combination process of capacitive screens. However, the white panel printed by this method has poor shading effect and poor adhesion, and is prone to shedding and light leakage.

Description

technical field [0001] The invention relates to the technical field of printing and preparation of mobile phone panels, in particular to a printing process for mobile phone glass panels. Background technique [0002] With the advent of the information age, as a communication tool for mutual communication and exchange, the role of mobile phones is becoming more and more important. The characteristics of diversification, fashion and rapid replacement of mobile phones are becoming more and more prominent. On the one hand, the ever-expanding mobile phone market has directly brought about a straight-up increase in the number of panel orders. On the other hand, the fashion and diversification of mobile phones has put forward more requirements for manufacturers. Screen printing technology is an important aspect in the production of mobile phone panels. The most important and one of the most critical processes. Design schemes with different requirements have different requirements...
