including developer temperature, amount of film
processed, amount of replenisher added, the person
who processed the film or control strip, and the time
of processing. By using a processing record form,
you can establish and maintain proper replenishment
rates and monitor the processing variables that affect
processing quality. When control strips indicate that
the process is, or is going, out of control, some
potential causes can be eliminated by checking the
processing record. This often makes it possible for
you to determine the source of the problem. Also,
when workers maintain processing records, they have
an added incentive to follow prescribed processing
procedures more carefully.
