Background

Screen printing and spraying are two ink printing processes which are commonly adopted in the market at present, wherein the screen printing refers to that a screen is used as a plate base, and a screen printing plate with pictures and texts is manufactured by a photosensitive plate making method. The screen printing is composed of five major elements, namely a screen printing plate, a scraper, ink, a printing table and a printing stock. The basic principle that the meshes of the image-text part and the non-image-text part of the screen printing plate are permeable to ink and impermeable to ink is utilized to print. When printing, ink is poured into one end of a screen printing plate, a scraper plate is used for applying certain pressure to the ink position on the screen printing plate, meanwhile, the ink moves towards the other end of the screen printing plate at a constant speed, and the ink is extruded onto a printing stock from meshes of an image-text part by the scraper plate in the moving process, but the printing process cannot meet the 3D special-shaped curved surface ink printing of mobile phone glass products and protective products (glass, sapphire, ceramic and other material products);

the spray coating is a coating method in which the coating is applied to the surface of an object to be coated by dispersing the coating into uniform and fine droplets by means of a spray gun or a disc atomizer by means of pressure or centrifugal force. The method can be divided into air spraying, airless spraying, electrostatic spraying and various derived modes of the basic spraying form, such as large-flow low-pressure atomized spraying, thermal spraying, automatic spraying, multi-group spraying and the like, so that the spraying can cause the volatilization of ink dust, and the waste of ink, environmental pollution and personal injury.
