摘要

Apparatus for exposing lithographic plates to light through a film, e.g. a negative, adapted for exposing a plurality of plates to light through the same film, having a conveyor with grippers for conveying a plate with a film thereon to an exposure station, where a window comes down on the film and plate, the grippers being opened to allow the window to vacuum-lift the film off the plate and retain it while another plate is conveyed to the exposure station for exposure through the retained film.
