Digital BW, The Print

Lou

That makes a lot of sense to me - at least given my current knowledge.  He
has matched his white point to his lighting.  The difference in gamma is
simply managed by colorsync (image file values are not altered until it's
edited - your workspace is more important for this reason).  (I am still
getting my head around setting the luminance.)  Do a soft proof with
Simulate Paper White (and Ink Black) checked and if you have a monitor white
point that matches your viewing conditions (checked by doing an incident
light reading) then you should get a very good match.  Else the Colorsync
software is flawed.  I suspect a big issue is that a lot of people don't
Simulate Paper White - especially if you are printing to matte paper,
checking that baby can be depressing as all that paper warmth and weak black
is displayed.  But that's reality.  RC paper (there's that term again) soft
proofs turn the white a little blue - again reality.

As for 1.8 vs 2.2 vs other, it's interesting to note that in an article on
the X-Rite website they mention there is a "proposed" "standard" which has
D50/1.8.
