i think they are two different approaches. b/w icc allows you to work with the color managment workflow and the epson print engine, while qtr alone allows you to control individual channels and their mixing very precisely.
personally i prefer the latter by a long shot, far easier to understand and to manage imho
Just starting to make b/w ICC profiles on my P800. they need a little tidying up.
Is this something that can be achieved with QTR Curve? if so what is the trick to opening files in this?
None of the saved data that I've measured with i1profiler will open in QTR Curve.
Any advice much appreciated.
