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.

Fixing: Adequate fixing is obtained at machine speeds up to and including 20 feet per minute.

Washing: With two developer racks, LE-100 keeping quality is obtained at process machine speeds up to 10 feet per minute, and LE-10 is obtained up to and including 20 feet per minute. (LE = Life Expectancy)

Drying: Adequate drying is obtained at machine speeds up to and including 15 feet per minute.
