In this demo Atsuhiko will demonstrate how to work with photopolymer plates.

This method will use Ultra Violet light to change the properties of the photopolymer. First a halftone dot screen is exposed on the photopolymer, followed by a second exposure with a drawing on mat, grained polyester film. Where the UV light hits the parts not protected by the drawing the film hardens. The unhardened parts can be washed out with water and this leaves a texture like that of an aquatint.

After hardening the plate can be inked and printed like conventional intaglio.
