[QUOTE=D-Nice;53354386]Here is the comparison. The i1Pro appears more accurate (sic) than the i1Pro 2 for Grayscale measurements. However, the i1Pro 2 is more accurate (sic) than the i1Pro when measuring the Gamut. Overall, I would be cautious when using either as a reference.[/QUOTE
D, thanks for doing this very detailed work. Really appreciate it
-670 is a 1 NM device where the i1Pro's are 10 NM devices so given that, the i1Pro is doing a very good job for non-production calibration. For production, I agree, a 5 NM or 1 NM reference device is needed along with it's magnitude higher cost.
Also, I thought that the i1Pro and the i1Pro2 are essentially the same devices with the i1Pro2 being more stable longer? I wasn't surprised that there are some slight variances between the two units that you have. What I do notice is that the PR
-670 and the i1Pro2 CMS sweeps "look" almost identical where the i1Pro2 varies a little, especially in Magenta. I know if you look at the numbers which is the reference, that it shows the Pro's very close but it is an observation that I wanted to point out.
It's good to see that you were getting "relatively" good results on your A1, especially with the CMS given that there are no controls.
What did you think of my color volume scans?
