[0002] Stencil printing is also called screen printing, which is a printing method that uses screen as the plate material. The specific method is to make two parts, the image and the plate film, on the printing plate. The function of the plate film is to prevent the passage of ink, while the image part is to print the ink on the substrate through external scraping pressure, thus forming a printed pattern;

In the production process, the most critical thing is "making the base plate". The plate making determines the quality of silk screen printing. The traditional screen production process is cumbersome and very complicated: the materials needed are: screen frame, mesh, photosensitive glue, film, exposure lamp, hair dryer, screen plate includes screen frame and mesh, first brush the photosensitive glue on the finished screen (mesh), wait for the photosensitive glue to dry, and then use the film to expose it. The black area of ​​the film plays the role of shielding the exposure light, so that the photosensitive glue is not cured during the exposure, while the transparent non-black area will be exposed and cured by light. After the exposure is completed, the uncured photosensitive glue is evenly washed away with water, and then dried, repaired, etc. The plate making device of this type of stencil printing machine is the plate making device for exposing the printing plate;
