The silkscreen process uses a mesh screen that could be made out of nylon.
The mesh of this screen is typically 240 to 400 lines per inch.
- The screen is coated with a light sensitive emulsion.
- The positive film is put on top of the screen under a large glass
and a vacuum sucks out all the air.
- The film and screen are exposed to UV light, hardening the emulsion.
- The screen is washed out with a solvent, leaving a negative image
in the screen
- the screen is put on the printing machine and flooded with ink
- a squeegee pushes the ink through the screen image onto the CD surface
