Gary, You also failed to mention what developer you use, whether you
humidify your paper or at what humidity range that you print in. As we
know, many different things contribute to the contrast of the print. The
strength of the developer, the type of developer, paper, etc.
It has been my experience that as you use a more dilute developer, the
contrast increases, as does the effect of enlarged grain with chlorate
use. Have you tried any of the dichromates? peroxide? using the Ammonia
based platinum with the Sodium based palladium?
A further explaination of your printing procdures might help open up the
discussion for you.
