  • Method for producing film exposed to different images
    Patent number: 4195995
    Abstract: A method produces a reproducible image on a film in a single machine. Steps include exposing the film to an image, passing the exposed film to a developing station and developing the film. An improved method controllably recovers the exposed film from the single machine without developing the film. The exposed film is subsequently exposed to a second different image in the single machine to form a composite exposed film. The composite exposed film is passed to the developing station and developed in the single machine to produce a composite image film for reproduction purposes.
