Abstract
The adoption of safety base film throughout the motion picture industry has required the abandonment of the Bell & Howell perforation for color release prints. This fact presents an opportunity to achieve the long-desired goal of a single standard perforation for negative and positive films in all applications. Tests are described and conclusions reached covering registration problems in the studio, studio laboratory and release laboratory, as well as accelerated and normal release life tests on Dubray-Howell perforated black-and-white prints.
