Always follow the health and safety recommendations on the packaging. Development can be extended up to 6 minutes without any noticeable change in contrast or fog. Stop Bath See the 'Processing summary' for stop bath recommendations. A stop bath stops development immediately, reduces the risk of staining and will extend the life of the fixer bath. A water rinse can be used instead of a stop bath, but it must be changed frequently to avoid processing marks.
Fixation See the 'Processing summary' for fixing recommendations.
The use of a hardening fixer is not recommended as it reduces washing efficiency. Washing See the 'Processing summary' for washing recommendations. After washing, squeegee prints on both sides to remove surplus water. The standard fixing and washing recommendations will give excellent print permanence for all commercial needs. Do not add a har ener to the fixer.
