ABSTRACT:
There is disclosed a method of producing an image of an original multi-color subject in polychromatic glass by employing, as a mask during initial exposure of the glass, a continuous tone, ultra-violet transmitting, film negative in which each color in the original subject is recorded in terms of a unique film density corresponding to that color in the glass and capable of conditioning the glass for development of such color by transmission of a single predetermined exposure flux. Methods of preparing the mask are also disclosed.
