Using Jobo Aerated film washer PMK-image stain...reduced time same stain?

[CropDusterMan]

Here's a question...living in California, water is at a premium, so conserving it paramount...

The Jobo Forced aeration washer is a great tool, reducing film wash times, but I'm curious if reducing
the film wash time with PMK while using the Jobo system could affect image stain...? I'm thinking it will.

Anyone out there had any experience with such. I can always do an experiment, just thought I'd get
some feedback first.

Jason,

PMK stain shouldn't be affected by wash times. That said, since you shouldn't be using a wash-aid with PMK (that'll remove the stain!), you should be sure you're washing thoroughly. A 30-minute wash is what you need for film when not using a wash-aid, whatever washer you're using. Don't be fooled into thinking that aeration or agitation will reduce the wash times much; it's a function of dispersion, not activity. If you need to save water, you can alternate periods of flow with periods of simply soaking.

If you look at the sticky thread on film washing (there was a url link here which no longer exists) there are lots of good ideas on the subject.

Best,

Doremus
