It's difficult to know what is actually happening without objective testing - which is not necessarily easy to do. But if it is working, I'd say keep doing whatever you're doing. We all learn to print with the negatives we make, regardless of whether or not they are exactly the way we think they are. There's enough room in the materials. In any case I was referring to more extreme contractions and dilute solvent developers.

Apologies to Mark if I derailed the thread. Back to his diagram now.
