Digital BW, The Print

I think you are both right.  BO only comes into play when its output
time, but an initial color to BW conversion does map the image (if
that is the correct term) to the default gray workspace.  So the
initial screen images for DG20 and GG2.2 conversions of the same color
image, for example, will look identical, but the initial prints will
be very different (assuming the printer profile is SAS).  However,
once converted and changed to grayscale, any profile may then be
assigned to an image, and only the screen image will change, not the
print (again, assuming the printer profile remains SAS).  Beyond that
I'm not sure what happens when you check the Black Only box, but your
description may explain what I've been experiencing. Changing the
driver gamma setting does change the print. Thanks.

Clayton
