Wanted: suggestions as to why a 3:1 ratio of pd:pt makes a great print
but the same neg printed with pure pt suffers from either weak blacks
(when single coated) or streaming (migration of metal into highlight
areas) when double coated. Here are the specs:
Paper: Bergger Cot 320
Ferric: fresh stuff mixed from B&S powder (fresh but aged several days)
Developer: Potassium Ox. at 110F.
Paper humidified before and after coating
I don't plan on printing with straight pt myself but was tyring to help a
friend when we encounted this problem.
Many thanks in advance for any helpful advice!
Dan
