1. Direct plate making method

Method: The method of direct plate making is to first place the photosensitive film coated with the photosensitive material on the surface of the work surface, and put the stretched wrist frame flat on the substrate, and then put it in the frame. The photosensitive paste is applied by pressure coating with a soft scraper, and after drying, the plastic film base is removed, and the photosensitive film wrist wire mesh is attached to the printing plate, and after development and drying, a screen printing screen is produced.

Process flow: stretched net → degreased → dried → peeled base → exposure → development → drying → revision → sealing net

2. Indirect plate making method

Method: The indirect plate making method is to expose the indirect film first, harden it with 1.2% H2O2, develop it with warm water, and dry it to make a peelable graphic film. When making the plate, the film film surface is tightly attached to the stretched wire mesh. The film is adhered to the wet wire mesh by extrusion, the film base is peeled off, and the screen printing screen is made by drying with the wind.

Process flow:

1) Stretched net → degreased → dried

2) Indirect film → exposure → hardening → development → lamination → drying → revision → sealing network

3, straight mixed plate making method

First, the photosensitive adhesive layer is pasted on the screen frame with water, alcohol or photosensitive glue, and after drying by hot air, the base of the photosensitive film is removed, and then the plate is printed, and the screen plate is formed after development processing.
