Digital BW, The Print

Steve-  

I believe that with color management turned off in PS (and no ICC 
Soft Proof profile) screen gamma may affect correspondence between 
screen and print.  The ABW driver has no way of knowing what you are 
viewing the file "at" in PS because PS is not providing information 
to the ABW driver without CM turned on (one way or the other).  If 
the file itself has an embedded  profile of 2.2 (which is what I 
think the ABW driver is expecting for "darker") then this might not 
make a difference and PS would also make it look "right" on the 
screen.  If on the other hand the file had an embedded profile of, 
let's say, Gray Gamma 1.8 or Dot Gain 20%, PS would make that file 
look right on the screen, but the ABW would have no idea.

Incidentally, I am finding the use of the QTR Create ICC profiles in 
Soft Proof quite useful in predicting the print.
