Interpretation of Dimensional Changes in Cellulose Ester Base Motion-Picture Films
The factors which affect the dimensions of solvent-cast, cellulose ester base motion-picture film are discussed in order to correct some of the misinterpretations that are sometimes made. The distinction between standard film dimensions at the time of manufacture and actual film dimensions at the time of use is clarified. The stacking or cancellation of dimensional errors caused by variations in cutting or perforating, relative humidity, temperature, processing and aging is explained. The application of the principles discussed to practical problems in the motion-picture and in the instrument and data-recording fields is illustrated.
