Digital BW, The Print

For those of you with Spectratone Dmax envy - and to prove Tyler's point
that my real life ended when I bought my first spectrophotometer, here is a
quick list of Dmax measurements for various papers and the Spectratone
inkset for the Epson Stylus 3000 printed with the standard RGB driver set on
backlight film.  Note that just because it has a high Dmax I don't
necessarily recommend it -- some of the clay papers print with a really
strange reddish cast (except Crane Museo which prints with a really strange
cyanish cast just to be different).  However, a lot of the clay coated
mattes and watercolors that aren't recommended by Lincoln Inks and Papers
(longevity issues I think) look really nice after they finish curing for a
few days.  The Arches papers listed are *not* the "bright white" variety.
Not sure if the Bulldog Photorag is still available but it is a gelatin
paper with a rather nice very light pebble finish much smoother than the Oce
texture (but it was hugely expensive a few years ago when I bought it).
Need to do further work with this one!   Konica QP and Tetenal have a high
Dmax but print horribly reddish with these inks.  The Ilford Glossy is still
king at 2.32 and spotlessly neutral.  Haven't yet tried any of my hand
coated (Knox gelatin) varieties with Spectratones but I would bet they do
well.

One final hedge -- some of the papers, like the Oce Watercolor and Somerset
Velvet Enhanced, *appear* to be darker in the shadow regions than a simple
Dmax reading would seem to indicate (comparatively).  This mostly has to do
with the paper fiber showing through on some papers with similar Dmax
readings.  Thus Arches Hot Press, with a slightly higher Dmax than Somerset
Velvet uncoated doesn't appear nearly as dark in the shadow regions right up
to the Dmax where the paper is fully saturated with ink and the fiber is no
longer evident.  Somerset Velvet has a surface quality that avoids show
through of the paper fiber and gives a better shadow region though not a
deeper Dmax.  So sometimes it ain't how Dmax it is, it is how you use it (or
something like that).
