ABSTRACT:
A latent image is produced on a metallic film having at least one layer of chromium or aluminum by exposing the film to a light pattern. The intensity of the light from the light pattern must be below the threshold for evaporation of the metallic film. The latent image is developed by dipping the metallic film into an etchant.
