ABSTRACT:
An apparatus for handling a substantially continuous strip or web of photosensitive material is provided with an overlying photographic endless master copy band caused to move in a path that includes a portion at all times in contact with a photosensitive strip or web. The superposed band and web travel through an exposure on an endless carrier band on which they are tightly pressed together by weighted transparent means through which exposing or printing light rays pass to impress the photosensitive material with images derived from the copy band. Following exposure the exposed material and the copy band separate, the latter moving on in its closed path for further printing and the former moving in a separate path to developing and fixing operations.
