Computerized Process and Printer Control: Part I: Color Positive Developing Control and Printer Tape Preparation

David J. Degenkolb, Harold W. Larson, Manfred G. Michelson, Fred J. Scobey

An assessment of color positive developing is made by analyzing a Ib gamma strip read on an automatic recording densitometer. The output of the densitometer is fed to a minicomputer through an analog-to-digital converter. The interpretation of the computer output is typed out as full instructions on a teletypewriter giving a decision as to whether the process is normal or abnormal and, if abnormal, it lists probable cause and corrective action to be taken. A further use of the computer is correcting printer punched-tape programs, which is a valued aid in timing color prints.
