Thanks all, just to clarify my negs are not so thin that they would be unprintable, in fact many of my older negatives are probably on the denser side of the spectrum. I've just always heard that a slightly less dense negative scans better and was considering targeting that. It seems rather that the best system would be to target easy to print in the darkroom negatives and then make the scans right with PS, as darkroom chemicals/paper cost much more then photoshop time (mine that is.)
Yep. While slightly thinner is easier on the scanner, the difference (with a good scanner) is minimal. Not worth significantly perturbing your process.
I aim for about Grade 3 on my negs and they both print and scan perfectly.
