What is the difference between Process C-41, C-41B, and C-41RA cycles?
· Process Cycle C-41 is used most frequently by commercial / professional labs with equipment that uses a water wash. · Process C-41B is a shorter process cycle than standard Process C-41. This cycle was made shorter by eliminating both washes and reducing fixer time. Originally the process used a final wash, but the most common version in use today is a “washless” cycle. · Process C-41RA has a shorter total process time than Processes C-41 and C-41B. To use this cycle, the minilab must be capable of providing the higher fixer and stabilizer agitation, and must use HCL HNRA-2R Bleach Replenisher and HCL HNRA-3R Fixer and Replenisher. Although Process C-41RA was designed to be a “washless” cycle, you can use it with a final wash.
