I finally got my POP printer friend over to compare prints exposed on her
Black Light 360nm bulbs vs. my Super Actinic 420nm's. Her prints were
exposed in half the usual time (10 mins. vs. 20 mins.) and were at least a
grade higher in contrast. She was quite pleased and is ready to buy Super
Actinics to replace her Black Light bulbs. We printed about 4 of her negs
and the results were always the same.
So, 420's are faster for both Pt/Pd and POP. Any data out there on Super
Actinics for other processes?
