Optical Reduction Sound Printing
The optical reduction sound printer was developed to provide a simple and direct means of transferring sound tracks from 35-mm. film to 16-mm. film, and its use resulted in the production of 16-mm. sound tracks of superior quality. The mechanical and optical requirements of the printer are discussed, and features of the process that led to the improved record quality pointed out. An optical system is described that was built to convert a re-recorder into an optical reduction sound printer.
