Indirect plate making method: the indirect film is first exposed, hardened with 1.2% H2O2, developed with warm water, and dried to make a strippable graphic negative. During plate making, the adhesive film surface of the graphic negative is closely attached to the stretched screen, the adhesive film is tightly attached to the wet screen by extrusion, the film base is removed, and the screen is dried by wind. Process flow: 1. Stretched wire mesh - degreasing - drying. 2 Indirect film - exposure - hardening - development - fitting - drying - revision - blocking. 3 Straight mixed plate making method: first, paste the photosensitive adhesive layer on the screen frame with water, alcohol or photosensitive adhesive, dry it with hot air, remove the substrate of the photosensitive film, and then print the plate. After developing, the screen plate is made.
