Abstract: Two existing test methods for measuring retained chemicals in processed films and papers have been slightly modified and used to predict image instability during storage. One method is a titration and the other is a silver stain test that is measured densitometrically. The methods are relatively insensitive to time-lapse between processing and analysis. One practical application of the methods is illustrated by a survey of Eastman Color Films processed by 28 motion-picture film processing laboratories. It is recommended that the simpler of the two methods, the CD-Index method, be used by processors of Eastman Color Films as a measure of the effectiveness of washing. A CD-Index tolerance value indicative of satisfactory washing is suggested for the Eastman Color Films. It is further suggested that processors of other products apply one of these methods.
