Screen Printing
  • The design is made and printed onto film positive with the design
  • then they get a screen made out of polyester which is  used to make to add the emulsion which is applied to light later on in the process
  • when the film is added on to the screen with the design and pressed on to the screen where they then expose it to strong light usually in a dark room
  • its then washed down after exposure leaving the design area clear of emulsion
  • finally the paint is spread
