Control and Prediction of Film Density and Color Balance in the Developing Process

When the Swedish Television Film Laboratory moved into new premises in 1983, a new technique was initiated to prevent pollution from developing agents. After some time there were increasing difficulties in keeping the control strips within limits. A survey of the working developing solutions was carried out in order to overcome this problem. The survey is a systematic procedure for determining the effects of mechanical and chemical variations on film densities. It was applied to the ECN-II process. The experimental part yielded the basis for an equation system, the solution of which is the key to a single corrective step. The result is the best composition of the tank solution and minimizes the overall deviation from specified reference values of the control strips. The formula for the developing solution was changed in accordance with the experimental results, and the strips have been satisfactory ever since.
