I did not use the 810 to make icc. If I remember well you have to input cie lab values into the qtr make icc, so I do not think the 810 will be of any use for that purpose. It gives you the relative density for each colour RGB, but unless you are aware of a methodology to make the conversion between the two color models, those values are not usable.
Well, my goal is to make an icc profile, and it seems like people are being able to do so just by feeding the icc maker an output file from eye-one, and nothing else. If I make the density text file alluded to in your writeup and only feed that to the qtr icc maker, will that work? Or is the .acv necessary too?
