Ilfochrome Classic process P-3X is a photographic process based on silver dye-bleach technology designed for the processing of Ilfochrome Classic papers and films in roller-transport or leader belt processors.
Replenishers and starter additives make it easy to use, very stable and economical. The chemicals are supplied in the form of liquid concentrates. Because of the low replenishment rates used, process P 3X only creates little overflow, which is favorable in terms of waste disposal.
The very low wash rates also contribute to lower the cost of warm water.
The Ilfochrome Process P 3X consists of three processing steps with intermediate, and final washes.
The P-3 Bleach process is the second part, in this bath the silver previously formed in the developer and the dyes incorporated in the layers are bleached simultaneously.
As the dyes can only be bleached in the presence of silver, the bleaching of the dyes automatically stops when all the silver is bleached out.
Note: If the process is correctly replenished and the necessary minimum throughput respected, the tank solutions will keep almost indefinitely.
The minimum daily throughput should amount to at least 10 % of the developer tank volume, expressed in square meters. For a machine with 40 liters of developer, at least 4m2 of material should be processed daily.
