9-20 Process ECP-2E Specifications

Formulas and Analytical Specifications

Maintain the fresh tank formula specifications exactly as given on the following pages. Any large deviations from tank
specifications, noted by chemical analysis, should be corrected immediately by appropriate additions or cuts to the tank solution.
Any long-term tendency to deviate from the tank analytical specifications (e.g., slowly increasing pH) should be corrected by
adjustment of the replenisher. The replenisher formula specifications are to be used as starting points for typical operations.
Important
Observe precautionary information on product labels and on the Material Safety Data Sheets.
Developer
To process VISION Premier Color Print Film, the normal replenisher flow rate must be increased by 8%. If the footage
processed is less than one tank turnover, no change of pH is required in the replenisher, but small adjustment could be necessary
in the tank processor. For larger quantity of VISION Premier Color Print Film (more than one tank turnover), it is recommended
to increase the replenisher pH to 11.45.

* The difference between the mix levels and the analytical specifications for CD-2 and sodium sulfite are to compensate for aeration losses that occur
during mixing and transfer of solution to the machine tank. The mix levels necessary to achieve the required analytical specifications will vary with
mixing equipment and solution transfer techniques.
