> Can I ask you what colorimeter / spectrometer you are using? > Stephan. I use every instrument I can possibly / financially put my hands on: Digital SwatchBook, EyeOnePro, Techkon SP810, DTP41uv, 530, Spectrocam, ICcolor. I don't have a Spectroscan yet but I'm have my eyes set on a DTP70 instead. Of course, argyll does not support all those instruments directly. I find that measurements do make a difference in the final rendering and neutrality. But on the 2200s, in RGB, using any of those instruments with other profilers never yielded better results than the canned profiles ! It could be that the host driver was, somehow, corrupted. But my client did not care for me to find that out. What platform are you driving your 2200 through? Regards, Roger Breton | Laval, Canada | graxx@xxxxxxxxxxxx http://pages.infinit.net/graxx
