Hi Tyler 

I don¹t know whether you have followed the discussion that Roy and I were
having about soft proofing (QTR question for Roy) but I was intrigued by
your comments below.   In the colour world one would choose an intent and
check Use Black Point Compensation.  Furthermore one would most properly
check Simulate Paper White (and, as a result, Ink Black).  Although many
find the initial effect of doing so quite off-putting it does actually lead
to better soft-proofing.  I was wondering what the difference is when in the
B&W world we check Preserve Colour Numbers (rather than using a rendering
intent).  How does Simulate Ink Black (and I guess one should also check
Paper White) work in a Preserve Colour Numbers world?  I guess at the heart
of this I am wondering why Preserve Color Numbers is used.  Because we use
Same as Source at printing?  Can you help me muddle through this?

 I find some very
critically chosen separations, particularly near 100%, more accurately
predicted with the icc soft proof profiles, particularly with ink
black checked.
Takes a while to get used to the look of it, but ink on paper always
looks so different than the monitor that I need all the help I can get.
Those with EyeOne Photo may want to give it a try, it's very easy to
do. If custom dot gain in PS had some more curve points, or allowed a
simulated dmax like profiles do, it would surely help.
