Digital BW, The Print

Josh - big subject.  It has been churned a reasonable amount under the
(heavy) thread ICC v. Transfer Function in Epson Driver.  Here's a quote
from my last post:

The "linearised L* output has good L* separation but is
flat and lifeless and we can readily see why from a quick sketch - the gamma
or contrast of the output is significantly less than "ideal".  If we are
going to restore this contrast into something visually appealing then
something's got to give so think either a handmade contrast s-curve or a
luminance-calculated ICC profile.  We readily recognise that the former
compresses luminance change at either end in order to restore contrast
through the important mid-tones."
