Problems solved by technology
The cover plate printed with ordinary ink has a monotonous appearance and dull color, and has gradually lost its market competitiveness. Although the coated cover plate in the market is bright and vivid in color, the color is single. Even adding nano-textures can only change its color brightness, and cannot To further improve its brilliance, this invention adopts a special coating method, which can make the mobile phone cover plate have two or more colors, and present special patterns according to the design

The invention discloses a method for preparing a coated cover plate with two or more colors. The method comprises the following steps: firstly, a glass substrate is pretreated, a layer of protective ink is printed on the glass substrate, and then a first vacuum coating film layer is prepared on the glass substrate which is printed with the protective ink; the protective ink on the coated glass substrate is removed, and cleaning is carried out, wherein the first vacuum coating film layer is not damaged; then a second vacuum coating film layer is prepared on the glass substrate which is subjected to protective ink removal and cleaning; and finally, the film layer of the coated glass substrate is covered with printing ink and curing is carried out. According to the invention, the glass substrate has different film layer structures, so that different colors can be presented, and two or more colors can be prepared on one cover plate. In addition, different patterns can be presented according to design requirements, so that appearance fashionability and diversity of the cover plate are greatly improved. Meanwhile, the preparation method is simple.
