Abstract

Transparencies are obtained by contacting polypropylene film, with transparency to visible light at least 60%, with original, radiating combination through film side shortly with IR light so that wrinkle image is formed by thermal structural changes on film side in contact with original. Exposure time is governed by speed of movement of combination across lighted area.
