Jeff,

Oxalic seems to be a good idea for this paper. Definite increase in dmax,
though most of the difference shows up in the fully black border. Actual
image tones aren't affected that much and a masked print may not really need
the pre-treatment. It requires an acid clearing bath: in EDTA/sulfite the
image area clears but the entire sheet takes on a yellow cast (from the
developer?) that needs acid clearing to go back to the original white. 2%
citric does the trick.---Carl
