Abstract: The introduction of new color emulsions to the industry makes it necessary for the sound engineer to investigate problems in connection with the recording and reproducing of quality tracks on this new medium. This paper is a discussion of the results of some preliminary tests made with variable-area tracks on Ansco reversible monopack color film. The tracks were processed in exactly the same manner as for picture and therefore are of dye composition. Three specific methods of printing are discussed. Quantitative measurements of tracks containing modulated and constant-amplitude tones reproduced with the new gas-filled blue-sensitive and the ordinary red-sensitive phototubes are given.
