Cranes Kid Finish was the culprit... I hadn't seen any problems with it before, but then again I never had it in liquids as long as I did for Pd printing. I thought I'd use a cheap paper for my first Pd prints ever.

I've tried Arches Watercolor with other processes (this is the heavier paper I mentioned above, heaviest I've used), and while not the best paper, it's very strong.

I probably just need to be more careful with the paper next time.
