Graphics Production Group has been in the business of producing film for years. We generate Positive and Negative film in standard sizes up to 30" x 40" using a Dolev imagesetter and Fuji processor.
The Basics of Using Film in Platemaking
Positive film is used in Positive Platemaking and conventional printing plate production. The positive film is used as the original with the blackened sections of the film correspond to the ink-accepting surface elements on the plate.
Negative Film is used in Negative Platemaking and negative printing plate production. The negative film is used as the original with the ink-accepting image areas of the printing plate correspond to the translucent, light areas on the film. The light-sensitive coating is hardened on the printing plate by light, so that it stays in place after the developing process, as opposed to the unexposed areas that are removed.
