To expound that...the papers specifically made for platinum printing (e.g. Cranes Platinotype and Arches Platine) are not buffered, so an initial acid bath is not required.

Besides you'll be clearing in an acid bath (citric acid, EDTA, HCl, whatever) of some sort anyway, so any buffering is pretty well eliminated just by virtue of that.

Avoid the paper chase. Pick a good paper, and stick with it until you've learned its qualities inside and out. If you still don't like it, move on, but don't be premature in decision making until you're sure your motivation is the paper and not something in your process.

Is anyone using Bienfang 360?
