ENTMERE PAN 400 Technical Information
Processing at Different Temperatures
KENTMERE PAN 400 film can be processed over a range of temperatures. Development times at temperatures
other than 20°C/68°F may be calculated from the charts below. For example, if 4 minutes at 20°C/68°F is
recommended, the time at 23°C/73°F will be 3 min and the time at 16°C/61°F will be 6 min.
PROCESSING
KENTMERE PAN 400 can be processed in all types of processing equipment including spiral tanks, rotary
processors, dishes/trays, deep tanks and automatic processors. Standard capacity figures and replenishment
rates can be maintained. KENTMERE PAN 400 is very robust in processing and will tolerate less than ideal
processing conditions. Also, it will not contaminate the processing chemicals.
Safelight recommendations
Handle KENTMERE PAN 400 film in total darkness.
Agitation
Intermittent agitation is recommended for use in spiral tanks and deep tanks. With spiral tanks, invert the tank
four times during the first 10 seconds, then invert the tank four times again during the first 10 seconds of each
further minute. Otherwise, follow the recommendations given by the processing equipment manufacturer.
Stop, fix, wash and rinse
For best results it is recommended that all process solutions are kept at the same temperature or at least within
5ºC (9ºF) of the developer temperature.
Stop Bath
After development the film can be rinsed in
water, but we recommend that an acid stop
bath is used such as ILFORD ILFOSTOP (with
indicator dye). ILFOSTOP is also
recommended for all machine processing
applications. When tanks or dishes (trays) of
process solutions are in use a stop bath
immediately stops development and reduces
carry over of excess developer into the fixer
bath. This helps to maintain the activity and
prolong the life of the fixer solution.
