I got to thinking today at the darkroom about having to spot some of the prints I was doing. then it occurred to me what others do about that. Specificly, in what sequence. I know they need to be dried. I generally flatten the prints first in the dry mount press then get out the triple 000 brush and do the spotting at that point. After that I mount and mat the print if I am to do that. Is there any advantage for the b/w practitioner to spot the print before they are flattened in the press?
We always spot after the prints have been mounted. As we are dry mounting the concern has always been about the relationship between the dye and heat. Never wanted to take a chance to test it out, and it has never been an issue doing it after mounting. just place a piece of clean board across the photo and spot away.
I do only portraits and retouch the negative first and then the print. The dye retouching is far more extensive than just spotting. If there is a lot to do I often do it before I mount the print because you can wash it off if you screw up.
More often than not though, I do it after the print is mounted because it is easier to work with a flat drymounted print.
I've never seen a color change from the heat of the press.
