Abstract: The use of sensitometry for process control and print-through evaluations in the motion-picture industry has been limited by labor-intensive manual techniques or expensive computer-controlled densitometers and calculations systems. By coupling a densitometer to a relatively inexpensive programmable calculator and a plotter, a sensitometric strip can be read and analyzed within 2 min. The programmable calculator collects and stores data from the densitometer. Through the use of a standard program, various process parameters can be calculated, and if desired, curves and trends can be produced automatically. The software and equipment design criteria are discussed, and the implementation of the system is shown.
