ABSTRACT:
An asynchronous contact printer and a related method for printing motion picture film in different formats. The contact printer has a pair of film drives that move duplicate film and original film at different increments through the printer, and then intermittently stop the film to permit exposure of the original onto the duplicate. The printer can print duplicate film in an alternate format, such as the three-perforation or 2.5-perforation format, from original film in another format, such as the four-perforation format. This is accomplished by moving the film asynchronously through the printer and exposing frames of the original film onto the duplicate film on a frame-by-frame basis.
