Hi Mike,
i wrote "good middle class" :) OK, OK, "well done, good job" was definitely more appropriate, i was just little bit disputing "best on the planet".
IMO, technically speaking, depends on what we measure. If you measure little bar (Fogra), it is no matter if you get average 1,1 or 0.90, particulary with regard to instrument precision. But if you measure big target (ECI), improving in both values, average and max, is a bit more important.
But i agree with your statement about printer drifts - and there are many others practical issues which affects proof precision far more, than few tenths of deltaE.
Best regards,
Kamil
>I haven't seen the blog in question, but your characterization of 1.05/3.10 as "middle class" for a proofing system is not correct, as anyone who installs these systems >knows (and Dan is among this group). In fact, in general, only systems that have some sort of iterative "tuning" of output profiles (e.g., GMG, ORIS, XF can do better than >this immediately after calibration, and even then the improvement is vanishingly slight and the ultra-low numbers rise very quickly as the printer drifts in regular use.

>> You can do this in the new i1Profiler software. You can compare to the 24 ColorChecker values or to printing standards/specifications like GRACoL or Fogra. You can read more in the blog I wrote about it here: http://everydaycolormanagement.blogspot.com/2012/01/eizo-vs-nec-monitor-calibration-with.html.
