Preparation method for glass plate with color ink pattern, and glass plate

Abstract

The invention provides a preparation method for a glass plate with a color ink pattern. The preparation method comprises the following steps: a, cleaning a toughed glass substrate; b, coating the entire surface of the clean glass substrate with a wet-film photoresist and pre-baking the wet-film photoresist, or laminating the clean glass substrate with a dry-film photoresist, and then removing the photoresist located at a position where eventual formation of a first color ink pattern is needed through exposing and developing procedures; c, spraying first color ink on the entire photoresist surface of the glass substrate obtained in the step b, and carrying out baking to immobilize the ink; d, peeling the entire photoresist film layer of the glass substrate obtained in the step c by using a photoresist stripper solution so as to left a pattern formed by the first color ink; and e, spraying bottom-color ink onto the entire pattern surface of the glass obtained in the step d and carrying out baking so as to obtain the glass plate with the color ink pattern. With the method provided by the invention, the elaborate color pattern with straight edges can be obtained on the glass plate.

Description

technical field [0001] The invention relates to the field of glass plates for electronic products, in particular to a method for preparing a glass cover plate containing colored ink texture patterns and a correspondingly prepared glass plate. Background technique [0002] There are mainly three kinds of exterior patterns of existing glass cover plates. The first type of glass cover plate is generally solid color without patterns formed by colored ink lines. The second is to form a brushed texture on a glass cover with a solid color background color. Generally, the depth of the brushed texture is used to display the pattern. Therefore, inks that are inconsistent with the background color are generally not used in the brushed texture, such as the ink in the Xiaomi Mi 5 mobile phone. The glass cover is this type. The third type of glass cover is generally to print the color ink texture pattern on the glass first, and finally print the background color. For example, finally rea...

Problems solved by technology

[0004] From the above, it can be seen that only the third case in the prior art can obtain a "glass plate with a pattern of colored ink lines", but the resolution of the colored ink lines produced by this printing method is poor, and the edges are not straight enough. Appearance of glass plate products with patterns; and this method can generally only print color ink lines with a line width greater than 75 microns, but this method cannot be used for color ink lines that require finer line widths

In addition, when the glass plate is a non-planar 3D plate, if the pattern of colored ink lines is directly printed on the 3D plate, the printing effect on the curved surface will be too poor
