Digital BW, The Print

Roy, you might try printing a file in a different space and use your
new profile as the print space and see how it looks compared to the
monitor.
Just might work.
Personally I prefer working and editing in the space "linearized to"
for grayscale, less loss in the end I think.
But some people might find it useful if it works. Back when I was
testing QTR I made a custom gray space that visually matched it's
output on the monitor and printed to QTR through it, seemed to work fine.
