Thanks for this info. So it really is the paper. Darn, I got a deal on
50 sheets of the stuff.
I got good cyanotypes with the white Rives BFK. I don't seem to have
the time to make the big negatives for contact printing when doing
the cyanotype or gum prints. I am working on getting more time.
Thanks to all who responded. I'm gonna try the Sprint stuff and keep
the trays covered. Another part of the problem is that I insist on
using the standard full sheets of paper so I got a lot of chemicals
out at one time.
