Problems solved by technology

However, due to the need for two screens with complementary patterns in the production process, the process is complicated, so this method can only produce glass with simple patterns that can change patterns with the viewing angle.
[0005] In order to make the glass of the mobile phone present a three-dimensional effect, the current common processing scheme uses black ink to match the 2D flat glass, and the visual effect it presents is flat and has no bright spots. Although the 2.5D curved glass developed later will show different visual effects when viewed from different angles , but because the edge of the protective glass is thinner than the central area, the strength of the edge glass has been greatly weakened, and the chance of breaking the edge will increase

Abstract

The present invention relates to the technical field of mobile phone glass printing, in particular to a main body printing process of mobile phone glass, comprising the following steps: A, the first mirror silver printing: use screen printing technology to scrape mirror silver printing on the lower surface of the glass white sheet layer; B, the second blue-purple printing: scrape the second blue-purple printing layer on the lower surface of the glass white sheet using screen printing technology; C, the third pearlescent white printing: use Screen printing technology scrape the third pearl white printing layer. The present invention uses a composite printing process of the first mirror silver printing, the second blue-violet printing and the third pearl white printing on the glass white sheet, so that the printed pattern has a three-dimensional effect, and the transition between different ink layers is natural. The invention has the advantages of simple process, convenient operation and control, stable quality, high production efficiency and large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of mobile phone glass printing, in particular to a main body printing process of mobile phone glass. Background technique [0002] At present, the cover glass of mobile phone in the industry usually adopts the scheme of direct printing of ink on the lower surface to achieve its positive visual effect. Most of the ink color is mainly black, and other colors are used due to the uniformity of ink color, resulting in differences in visual effects. [0003] The Chinese invention patent with application number 02109830.1 provides a method for producing concave glass. The method is to emulsify the cleaned flat glass on one side and then screen-print it with a pre-designed pattern, then soak it in a corrosion tank, wash it after soaking, then soak it in a sodium hydroxide tank, and wash it again. Remove the anti-corrosion ink, then wash and dry to complete the finished product. The concentration of hydrofluoric ac...
