Problems solved by technology
Because, in the coating of PC, acrylic and other sheets, the cost of coating is high and various defects appear after the sheet is coated, resulting in a decrease in the product qualification rate
Moreover, after direct ordinary printing with mirror silver ink, there will be reactions between the ink and the additives in the ink, resulting in spots on the mirror surface, which cannot achieve the bright mirror effect

Embodiment Construction
[0020] Below in conjunction with mobile phone lens adopting PC sheet material printing process to further illustrate the present invention, its specific process steps are as follows:
[0021] (1) Manuscript production and film output: carry out computer processing according to the design pattern, and then use laser phototypesetting technology to make film;
[0022] (2), sheet material pretreatment: first adopt pure water to clean sheet material, then put into oven and bake, and baking temperature is 75 ℃, and baking time is 62 minutes;
[0023] (3), photosensitive plate making:
[0024] ① Stretch the screen: Stretch the screen on the screen frame to make a screen printing plate, the tension of the screen is 25N / cm; the screen adopts T300 mesh screen.
[0025] ②Coating photosensitive glue: Put the prepared screen printing plate on the coating machine to coat the photosensitive glue. The thickness of the photosensitive glue is 7μ, and then put it into the oven for drying. The t...

Abstract
The invention relates to a printing process of sheet materials for a mobile lens. The printing process adopts a wire mesh forme and silver printing ink for printing the surface of the lens and simultaneously uses a tunnel furnace and an oven to bake, so that the brightness of the surface of the lens achieves the brightness effect of a metal membranous layer. The printing process comprises the following steps: firstly, manufacturing a manuscript and outputting a ruling film; secondly, preprocessing the sheet materials; thirdly, sensitizer stencil making (stretching, coating photosensitive emulsion, and exposing and developing); fourthly, preparing the printing ink; fifthly, printing; and sixthly, baking. The invention has the advantages that because the plating films of the sheet materialsand the corrosion process after being printed are eliminated, not only the appearance defect generated in the plating film and the corrosion is indirectly eliminated and the yield of products is improved greatly, but also the productive efficiency of the products is improved.
Description
technical field [0001] The invention relates to a sheet surface printing process, in particular to a mobile phone lens sheet printing process. technical background [0002] At present, the mobile phone lens protection screen requires a high-brightness metal mirror effect, and this effect is all made of metal coating technology. Because, in the coating of PC, acrylic and other sheets, the cost of coating is high and various defects appear after the sheet is coated, resulting in a lower product qualification rate. Moreover, after direct ordinary printing with mirror silver ink, there will be reactions between the ink and the additives in the ink, causing spots on the mirror surface, and the bright mirror effect cannot be achieved. Therefore, in the process of trial and error and development, it is an important issue for technicians to explore how to use screen printing technology to replace the traditional metal coating technology to realize the printing of mobile phone lens ...
