Digital BW, The Print

There is an  explanation of the Arches Bright White papers at
http://www.handprint.com/HP/WCL/paper2a.html.  Perhaps the "smooth" variety
that folks are looking for is the 300 gsm version (smoother than the 640
gsm) rather than a hot press bright white.  At any rate the site has an
interesting review of the Arches papers.
