Digital BW, The Print

Dean

You can always use just one curve by selecting 100-0 or 0-100.  And it
doesn't have to be neutral.  For example, if you wanted sepia then you would
just select sepia 100 and x 0.  Re soft proofing the technique is referenced
on Roy's site:

http://harrington.com/QuadToneRIP.html#softproof

See the "download this" part.  You need an Eye One to do it.  Net net though
I think you will likely softproof hue less than the tonal compression part.
I would keep the step wedges for different curve mixes on the same page as a
ref, soft proof the tonal compression with the printer ICC profiles and test
print your curve mix with a full print.  Hope this makes sense (Friday night
and a few vodka gimlets under the belt...   :-)  )
