Digital BW, The Print

I'm not sure why the "barrier-paper" (RC) prints get a higher dmax but with
a "Photo K" that is less dense on matte paper.  The surfaces of these glossy
papers are just a different animal.  Perhaps it's the inherent smoothness --
or lack there of -- that allows a different coating type or the
characteristics that give rise to these differences.

Paul? Anyone? How does a barrier-type paper effect Dmax?
