Can I ask why you need to have such precise results Donald if its for the Web the variation between different set-ups makes it a waste of time... And if it is for colour printing Why not save the best settings for your Printer? Or have I missed the point? I use the Adobe tool to set up my system and the Colour Prints from my Canon A3 are superb after some tweaking..
