Digital BW, The Print

I noticed that too. Lightroom doesn't have soft-proofing yet either.
The color-engine in Lightroom (although solid) isn't totally fleshed
out. I'm assuming (I hope rightfully) that Adobe will fully develop it
in the next updates. It could be an issue with the ProPhoto
source-space. I noticed that Lightroom out-put to older 9600 drivers
doesn't work because those drivers can't do the conversion from source
profile to output profile correctly. As an organization, tiling, and
processing program it's pretty good so far. And in comparison to
StudioPrint (that doesn't have profile support for monochrome printing
either) it's totally there.

take care, Walker
