Developer Temperature

[1] Record the developer temperature recommended by the film manufacturer for
your:
• type of film
• developer (chemicals)
• Processor
• length of developer immersion time
[2] Record this value on the control chart.

Daily Processor Quality Assurance

[1] Expose and process a sensitometric strip each morning.
[2] Use a Densitometer to read the values for the following processor variables, using
the same gray scale step numbers recorded on the control chart:
• Speed Index
• Customer Upper Density Point
• Base+Fog
[3] Plot the values and the measured temperature on the control chart.
[4] Evaluate the results and make the necessary adjustments before processing any
