Large Tank Rack-and-Tank Processors
The development times for large-tank rack-and-tank
processors are based on a machine speed that transfers
the film every 2 minutes. The times given below are
starting-point recommendations for T-MAX RS Developer
and Replenisher and XTOL Developer. Make tests to
determine if results are acceptable for your needs.
Replenishment Rates
T-MAX RS Developer and Replenisher—Add 45 mL
(1.5 ounces) of replenisher solution for each 135-36 or 120
roll or 8 x 10-inch sheet of film processed. Stir or
recirculate the solution after each addition of replenisher
solution.
Note: Do not use T-MAX RS Developer and Replenisher to
replenish T-MAX Developer. They are not designed to
work together.
XTOL Developer—Add 70 mL (2.4 ounces) of replenisher
solution for each 135-36 or 120 roll or 8 x 10-inch sheet of
film processed. Stir or recirculate the solution after each
addition of replenisher solution.
RETOUCHING
You can retouch KODAK PROFESSIONAL TRI-X 400 Film
(135 and 120 sizes) on the emulsion side. You can retouch
KODAK PROFESSIONAL TRI-X 320 Film (120, 220 and
sheet sizes) by applying liquid dyes to the base or emulsion
side. You can also use retouching pencil on the base side
after applying KODAK Retouching Fluid.
Compared to KODAK TRI-X Pan and KODAK TRI-X Pan
Professional Film, the newer TRI-X 400 and 320 Films may
have a slightly different retouching “feel”.
