P5 PLUS Technical Information
DEVELOPMENT TIMES
The table below gives development times for both manual and machine processing HP5 Plus. These times will
produce negatives of average contrast suitable for printing in all enlargers. The development times are intended
as a guide and may be altered if a different result is needed.
For manual processing in spiral tanks and deep tanks, the development times are based on intermittent
agitation. Where continuous agitation is used for manual processing (as in a dish/tray or with some types of
developing tank), reduce these times by up to 15%. For use in rotary processors without a pre-rinse, reduce the
spiral tank development times by up to15%. A pre-rinse is not recommended as it can lead to uneven
processing.

Note. Development times may need adjusting to suit individual processing systems and working practices. If an
established system is producing good results, adjust the recommended development times until the desired
contrast level is obtained. Development times in other manufacturers’ developers are included for your
convenience and are only a general guide. Other manufacturers can and do change their product
specifications from time to time, and the development times may change as a result.
