Sorry, forgot that we have scientists here. I will print ang make the
test when I have a minute.
How about using ProfileMaker 5.0.10 on SL with Epson 9880 freshly
linearized with gmg colorproof 5.1?
I will use both non uv i1pro rev D (year old with minimal use as I
have 4 of them) in iO rev 2 (2 weeks old) and non uv isis A4 rev A
(about 3 years old but recently re-certified).
I will print a chart for eack spectro and read each chart twice.
Which chart should I use? Is 918 RGB from Bill Atkinson enough?
Will provide results from pmp.
Or anyone has a different preference?

Hi Derek
2010/3/2 Derek Lambert <email@hidden>:
Isis is much more accurate. Maybe .2 dE difference reading the same
chart.
On iO with rev. D i1 I can get .35 - .4 dE.
Just a plea for a scientific approach.
Is 0.2 dE the mean, max or maybe median? What about replicates and
standard deviations? Is 0.2 dE significantly different to 0.35 dE?
Statements like "much more accurate" need some underlying proof.
