ILFORD PQ UNIVERSAL
ILFORD PQ UNIVERSAL is a liquid concentrate developer suitable for the dish/tray developing of all RC and FB black & white photographic papers.
With excellent keeping properties, PQ UNIVERSAL gives a slightly warm image tone with most black & white darkroom papers. Supplied as a concentrate, it is typically used at a dilution of 1+9.
When a fast working, high contrast developer is needed and a high degree of enlargement is not required, PQ UNIVERSAL can also be used to dish/tray process technical films such as ILFORD ORTHO COPY PLUS as well as some photographic sheet films (see the tech data sheet).
