PROCESSING
In rotary processors, drum, cover and film reeds are to be cleaned thoroughly with

warm water after each development process. Before each new process they must be
absolutely dry.
Certain plastics absorb traces of the colour developer strongly and permanently.

Consequently, rotary equipment with trays and other parts made of plastics are not
suitable for this process.
The first developer is the critical phase of the process. Time, temperature and agi-

tation must be constantly monitored. Deviations from these conditions will impact
on veiling (minimum density) and loss of sensitivity (density). Any contamination of
the first developer with even the slightest traces of the colour developer (including
vapour) results in lower final densities (maximum density).
Used and unused solutions should not be mixed because of possible contamination.

INFLUENCE ON COLOUR BALANCE
The colour balance can be affected by a change in the pH value of the colour developer.
Reduction of pH value –> addition of 20% sulphuric acid (H
Increase in pH value –> addition of 20% sodium hydroxide solution (NaOH), abt. 4-6
ml per litre.
