KODAK TRI-X AEROGRAPHIC Film 2403 KODAK TRI-X AERECON Film SO-050 • AS-24 3
PROCESSING
KODAK TRI-X AEROGRAPHIC and AERECON Films
can be processed in the KODAK VERSAMAT Film
Processor, Model 11 or 1140, with KODAK VERSAMAT
885 Chemicals, KODAK VERSAMAT 641 Chemicals, or
KODAK VERSAMAT Chemicals, Type A.
Mechanized processing in roller-transport processors
offers the advantages of uniform treatment of all portions of
the roll, freedom from banding, and absence of significant
density variations from ends of the roll to the center. Refer to
the operator’s manual for the processor set-up information,
but in all cases, the fixer replenisher should be introduced
into tank No. 5 of the processor with a countercurrent flow
to tank No. 3, where it overflows to a collection or recovery
system.
General instructions for setting the machine dryer
temperature are included in these pages. However, the
temperature of the dryer may require some further
adjustment, depending upon the ambient temperature
conditions in the processing area. Usually it is best to set the
temperature approximately 3
°F (2°C) above that required to
dry unexposed, processed film.
