With your SA method we are literally stripping out all of the papers prepared sizing and starting with a pristine sheet of rag paper. It is more difficult to clear in that there is no sizing to prevent the emulsion into settling deep within the paper fibers.

Hi again Stan, I don't think sulfamic acid does anything to the sizing of Fabriano papers; to my knowing those are sized with AKD, and sulfamic acid doesn't attack AKD. I haven't noticed a change in the absorption characteristics of the paper myself... (That's for FAEW SP.)
