Cold tone additive for developers:
The quantity for 1 litre working solution is between 2 - 15ml. With higher dosage the exposure time has to be prolonged.
This additive is only conditionally suitable for developers of other manufacturers, as it contains a highly effective combination of development retarders which influence the reduction capacity. The development times have to be extended, the required amount has to be determined by tests. As a rule, from 6ml the exposure time must be increased by 10% for each additional millilitre.
