From a review of causes of film retake, the important role played by film processing technique is evident. In this study, a) we standardized the technique of daily monitoring the performance of film processor (whether automatic or manual) using the sensitometer & densitometer b) evaluated the significance and contribution of quality control in routine monitoring of performance of 3 types of automatic film processors & c) used the processer status to guide the exposure. Our experience with 750 evaluations is presented. The results show that the frequency of intervention in adjusting the temperature of automatic film processor was 22% and that of the adjustment of exposure 15%. This highlights the utility and necessity of routine quality control on day-to-day basis even for automatic film processors.
