Standardization of Sound Negatives and Prints
It is suggested that the SMPTE develop and provide a Standard Negative Test Film and a Standard Print-Test Film both standardized especially for cross-modulation characteristics, the print having minimum cross-modulation at a unified density. A method is outlined whereby each negative recorder preparatory to recording production sound negatives would be adjusted so that if its recordings were processed to certain specifications, it would produce negatives with printable characteristics identical to those of the Standard Negative. Similarly, each printer would have specularity of printing light adjusted so that when its Sound Negative Test Film prints were processed to certain specifications, the prints would have a unified density and minimum cross-modulation. With this method all negatives could be handled interchangeably and indiscriminately, from all recorders to all printers, with improvement in operating efficiency and economy.
