I would say the .4 dE consistency range for the iO is being kind....I've seen much greater than that.
And .2 dE for the iSis is perhaps being a bit UNkind...I typically see sub-.10 dEs when remeasuring a chart.
Putting it simply....if you have something as accurate (yes, that's the right word here) as, say, a GMG Colorproof RIP that is capable of sub-.30 average dE values to a reference, the instrument you're measuring with can easily be the limiting factor. Personally, I wouldn't own an EyeOne iO with a GMG RIP but would instead use either an iSis or DTP70. I'd rather have the accuracy of the RIP's color engine/CMS be the limiting factor and not the measurement device.
But for profiling on a wide array of substrates AND where sub-.50 dE consistency and accurate proof/print-to-reference isn't necessarily a priority, the iO is perfectly fine.
Frankly, if it were me and I needed the iO's flexibilitybut needed better consistency, I'd go looking for a good used Spectrolino/Spectroscan. Still can't beat those for consistency and versatility....they're just a bit slow is all.
