China's best screen printing screen making technology

There are many manufacturers in China who are engaged in screen printing meshs and screen printing mesh manufacturers. There are very few qualifications and production technologies. Maishi is a family. Maishi technicians informed the following screen printing screen making method:

(1) Photosensitive film direct plate making method

Method: The photosensitive film is commonly called water film. It is made of transparent plastic film with a thickness of 0.1mm. The enamel is coated with a certain thickness of sensitizing emulsion on one side. When used, the screen is fully wetted and then affixed. The upper diaphragm is adsorbed onto the screen by capillary action, and after drying, the plastic base is peeled off for exposure and development, and finally the desired pattern is obtained.

Process: stretched net - skim - wet - film - drying - reinforcement - exposure - development - drying - revision - sealing network

(2) Photosensitive pulp direct plate making method

Method: Applying a certain thickness of the photosensitive paste (usually diazonium salt photosensitive paste) on the stretched screen, drying after coating, and then using the plate-making negative film to fit it into the printing machine for exposure, developing and rinsing After drying, it becomes a screen printing screen.

Process flow: photosensitive paste preparation has been stretched - degreasing - drying - coating film - drying - exposure - development - drying - revision - final exposure - sealing network

2. Direct indirect plate making

The method of direct indirect plate making is that the photosensitive film-coated photosensitive film is first placed on the work surface face-up when the plate making is made, the wrist frame is placed flat on the substrate, and then placed 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: stretched net - skim - drying - peeling film base - exposure - development - drying - revision - sealing network

3. Indirect plate making

The method of indirect plate making 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 graphic film surface is tightly attached to the stretched wire mesh. The film is adhered to the wet wire by extrusion, the base is peeled off, and the silk screen is made by drying with the wind.

The method of making the screen printing screen is the above. hope it helps you!
