Recommended Agitation: Agitate continuously for first 30 seconds of development, then provide agitation of 5 to 7 inversion cycles for 5 seconds every 30 seconds for remainder of development time.


Where continuous agitation is used for rotary processor, reduce the developing times by 15%.

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 is obtained.
