Process ECP-2E Specifications 9-25FixerTo be used with persulfate bleach (may also be used with alternate process bleaches)To process a large quantity (more than one tank turnover) of VISION Premier Color Print Film, the normal
replenishment flow rate of the fix may need to be increased by up to 30%.

Alternate Process Fixer

(can be used with alternate process bleaches, not persulfate)To process a large quantity (more than one tank turnover) of VISION Premier Color Print Film, the normal
replenishment flow rate of the fix may need to be increased by up to 30%.

Fixer pH may decrease with certain operating conditions when electrolytically desilvering the fixer. If the fixer is not desilvered or desilvered by the
batch method, the replenisher pH should be 5.00 ± 0.015. Care should be taken to avoid fixer pH lower than 4.5 since lower fixer pH could cause
sulfurization of the fixer.
