Problems solved by technology

However, due to the surface tension between the glass substrate and the paint, it is easy to accumulate oil on the edge, and the effect is not ideal. The angle of the spray gun is high when spraying, the waste of paint is serious, and the control of the gradual interface is difficult.
However, the equipment for electroplating color gradient is expensive, which leads to high production costs and cannot meet market needs.
The printing method adopts dot gradient screen printing, while the traditional dot printing is to print another color directly on the basis of printing one color. In this method, the gradient effect produced by superimposing the two colors is not obvious, and the transition is not natural. , thus greatly affecting the appearance of the color gradient on the surface of the glass cover

Abstract

The invention discloses a glass cover plate surface color gradient printing process and relates to the technical field of cover plate surface processing. The printing process comprises the steps of (1) manufacturing a five-layer screen printing plate; (2) conducting screen printing through A-color printing ink; (3) conducting screen printing through B-color printing ink; (4) conducting screen printing through white semi-transparent ink; (5) conducting screen printing through white ink; and (6) conducting screen printing through black ink, wherein the color A and the color B are different colors. According to the glass cover plate surface color gradient printing process, the structure of the screen printing plate is designed, and multiple layers of ink in colors is printed on the surface ofa cover plate through the screen printing plate; through mutual overlapping and permeation of the multiple layers of the ink, the natural gradient effect of the colors in a printing region is achieved; the gradient colors are uniform, natural, clear and not dull, and the appearance visual effect is good. Through the glass cover plate surface color gradient printing process, there is no need to purchase expensive equipment, the cost is low, the preparation process is simple, and the process meets the requirements for industrial production.

Description

technical field [0001] The invention relates to the technical field of surface processing of glass cover plates, in particular to a printing process for color gradients on the surface of glass cover plates. Background technique [0002] Cover Glass (CG) is widely used in electronic products, but it is difficult to directly form a color gradient effect with high precision on the cover glass. At present, the methods of forming a gradient effect on the surface of the glass cover are roughly divided into three types: spraying, electroplating, and printing. Among them, spraying is to spray colored liquid paint onto the surface of the glass substrate, and achieve uneven coating thickness by controlling the spraying angle. The gradient of the color also has two-color spraying, spraying two different colors or glossy coatings on the same glass substrate. However, due to the surface tension between the glass substrate and the paint, it is easy to accumulate oil on the edge, and the ...
