Screen printing plate making method: direct plate making and indirect plate making
1. Direct plate making method
Method: The method of direct plate making is to first spread the photosensitive film on the working surface, spread the photosensitive material on the base of the wrist board, spread the elongated wrist grid on the film base, and then put the photosensitive paste on the grid, using A soft squeegee presses the photosensitive film, takes out the plastic plate base after it is completely dried, and then uses the sensitive film attached to the wrist to make a plate. After the screen is developed and dried, it can be made into a plate.
2. Indirect plate making method
Method: The method of indirect plate making is to expose the indirect film first, harden it with 1.2% hydrogen peroxide, rinse with warm water, and dry to make a peelable graphic negative. When making a plate, stick the film surface of the graphic negative on the elongated screen, press the film on the wet screen, remove the film base, and dry it with air to make the screen.
The photosensitive adhesive layer is first pasted on the screen frame with water, alcohol or photosensitive glue, and dried by hot air, the base of the photosensitive film is removed, then the plate is exposed, and the screen is formed after development.
