Puretch Photopolymer films

Puretch can only be used as an etching resist, because the film is very thin, much thinner then ImagOn Ultra rapid, DK-film or Z*Acyl. The film is laminated on a copper plate and exposed to UV light through a transparent positive image. The film is washed out in a soda sulution, only the exposed and hardened parts remain on the plate. The plate is etched in ferric-chloride, inked and printed. Very fine details are possible. This film cannot be used for Ïntaglio Type", this film is not thick enough to hold a dark black.

Puretch photopolymer film 61cm x 3 mtr (24"x10')

重 量: kg

Puretch is special because it is thinner than Imagon or DK-films. This makes it ideally suited to serve as a light-sensitive etching ground.

Warning: Prolonged exposure to temperatures higher than 23 ° C can cause damage. The film is made up of 3 layers; 2 transparent plastic layers and in between the photopolymer as a gel. If this gel melts locally, so that the 2 plastic layers touch, the film cannot be used at this location. Sending the film at higher temperatures is at your own risk.
