Kodak C-41RA manual Process RA-4 Cycle-Average Utilization, Process RA-4 Cycle-High Utilization

Process RA-4 Cycle—Average Utilization

This cycle is appropriate for processors with average utilization—i.e., a developer tank turnover occurs at least once every four weeks.

* Immersion time plus crossover time to the next tank. For best results, use the recommended times with crossover times of 6 seconds or less.

†This developer may not yet be available in your country. If not, use EKTACOLOR PRIME Developer Replenisher in a processor with

average utilization.

‡Use four countercurrent-flow stabilizer tanks with equal times in all tanks (0:23 in each tank). With three countercurrent-flow tanks, use a replenishment rate of 495 mL/m2 (46 mL/ft2); with two countercurrent-flow tanks, use 970 mL/m2 (90 mL/ft2).

If your minilab uses a countercurrent-flow wash instead of a stabilizer, use a wash-water temperature of 30 to 40°C (86 to 104°F). For wash times of 1:30 or longer, the wash-flow rate should be between 2160 and 10,800 mL/m2 (200 and 1000 mL/ft2). The actual rate depends on the number of tanks and the wash time (see KODAK Publication No. Z-100, Using KODAK Chemicals in Minilabs, or Z-130, Using KODAK EKTACOLOR RA Chemicals).

Process RA-4 Cycle—High Utilization

This cycle is appropriate for processors with high utilization—i.e., a developer tank turnover occurs at least once every two weeks.
