No thoughts, but wouldn't this be a fairly easy experiment to do, varying the time (immediate, overnight, 24 hours, 48 hours, etc.) on small identical prints?

Subject: MAY HAVE ASKED BEFORE? PT/PD TIME PAPER SITS 

DEAR LIST, 

I may have asked this before and, if so, here we go again. After coating and drying paper with pt/pd sensitizer solution and drying it, I often let it sit for a while (half hour to hour) and then rehumidify/expose/process the paper...as I feel most of us have done. 

THE QUESTION: How long can one let coated, dried paper sit before rehumidifying and exposing it? I feel that up to an hour is no big deal but what about 4 hours? 8 hours? 12 hours? Remember that the Palladio company used to sell precoated pt/pd paper and it worked reasonably well. I cut my alt photo teeth on that stuff in the mid 90s. In their case it sat for days or weeks at least. 

The reason I ask is that I am hoping to be able to either coat at night and rehumidify/expose/process the next morning or coat in the early morning and rehumidify/expose/process that evening. I am guessing that I would have to do with the test strip(s) exactly the same procedure as I will do with the actual print...there by eliminating the variable of sitting time. 

All thoughts welcome but actual experiences with this more welcome! LOL!!! 

CHEERS! 
BOB
