A composite printing process of mobile phone glass with 3D effect

Abstract

The invention relates to the technical field of mobile phone glass printing, in particular to a composite printing process for mobile phone glass with 3D effects, comprising the following steps: A. Vacuum coating: After cleaning the glass white sheet, put it into a vacuum coating machine, and apply it on the glass white The upper surface and the lower surface of the sheet are electroplated with a high refractive index material TiO2 thin film layer and a low refractive index material SiO2 thin film layer in turn; B, main body printing: take out the glass white sheet after vacuum coating, and carry out on the lower surface of the glass white sheet The main body is printed to obtain the pattern area; C. Chemical etching: perform chemical etching on the non-pattern area after the main body of the glass white sheet is printed, and clean the chemically etched glass white sheet; D. Cover printing: print on the glass white sheet The printed pattern area of ​​the sheet body and the non-pattern area after chemical etching are covered and printed to obtain a mobile phone glass with a 3D effect. Through the above steps, the present invention can display 3D stereoscopic effects on the glass of the 2D mobile phone.

Description

technical field [0001] The invention relates to the technical field of mobile phone glass printing, in particular to a composite printing process of mobile phone glass with 3D effects. Background technique [0002] At present, the protection glass of the mobile phone cover plate in the industry usually adopts the scheme of direct printing of ink on the back side to achieve its frontal visual effect. Most of the ink colors are black and white, and other colors are used due to the uniformity of the 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 pr...

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] To make the mobile phone present a 3D visual effect, the current general processing scheme uses black ink to match with 2D flat glass, and the visual effect presented 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 glass at the edge has been greatly weakened, and the probability of breaking at the edge will increase
