Photographic Duplication of Variable-Area Sound Recordings
The factors influencing the sound-recording quality of prints made from duplicate negatives were investigated. Two photographic materials of different sensitometric characteristics were found to be suitable for use as master positives and duplicate negatives. No one set of density conditions on the duplicates produced optimal quality for all of the sound-recording characteristics simultaneously. It was found that a compromise resulting in near-optimal sound quality measured by each test can be made with some latitude in master positive-duplicate negative density.
