Well, that is it i think. I couldn't find either what i wanted about
profiling but after reading a lot of posted messages and the help
files in QTR I understood. Did you make a calibration target print
also? I found out that the grey values i measured where sligtly
different then the ones in the example profile i used. Also i used the
4X21 stepwedge because i encountered some banding with the profile i
made with the single 21 stepwedge. That was one of Roy's tip i saw on
this forum. Now i have perfect B/W images which looks exactly the same
 (well, almost) as i see on my monitor.
