Abstract

The invention relates to a printing process for mobile phone glass, in particular to a printing process for a mobile phone glass window. The printing process includes the following steps of A, first printing of a mirror-like silver logo layer, B, second printing of a pearly luster layer, C, third printing of three layers of white bottoms, and D, fourth printing of a matte black cover bottom layer. Ink colors of the mirror-like silver logo layer, the pearly luster layer, the three layers of white bottoms and the matte black cover bottom layer are in natural transition, the pearly luster effect of the pearly luster layer is highlighted through the three layers of white bottoms and the matte black cover bottom layer, and the pearly luster layer gives out metallic luster and has the serene, elegant and pearly effects through refraction of the ink layers; the total thickness of all the ink layers is only 19-33 <mu>m, and the good light permeability of the glass window is kept; moreover, due to the fact that a pearly luster pigment has a light receiving function, the light permeability of the glass window is improved, the pearly luster effect of the pearly luster layer is improved, different refracted luster effects at different angles are displayed, and layering and stereoscopic impression of patterns are shown.

Description

technical field [0001] The invention relates to a printing process of mobile phone glass, in particular to a printing process of mobile phone glass window. Background technique [0002] In the existing technology, the current mobile phone window glass 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 to cause visual effects. difference. [0003] 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 ...
