The following additive processes have been investigated: Agfacolor, Dufaycolor, and Finlay. Conclusions are based largely upon experience obtained in the practical use of the processes. The two subtractive processes investigated were Eastman Wash-Off Relief and Defender Chromatone. Here a systematic attempt has been made to analyze the factors which control the results and to eliminate difficulties by some method of control.
