Starting-Point Replenishment Rates—

Process C-41B

Process C-41

This process cycle is sometimes used in older minilabs. It most

commonly includes water washes. To use the washless version

of this cycle, follow the recommendations in the second

footnote under the table.

†
† Use a two-stage countercurrent-flow wash. For a single-stage wash,
double the replenishment rate.
If your minilab uses a final rinse step instead of a final wash, eliminate
both washes. Use three countercurrent-flow final rinse tanks with a
minimum final rinse time of 2:20 (0:47 in each tank). Use a final rinse
temperature of 38 ± 3°C (100 ± 5°F) and a replenishment rate of
40 mL/135-24 roll (36 mL/m).
