Hello!
List seems to be a bit quiet so here something to ponder...
I have been doing some comparison on these three profiles and some comments
on those
When looking at Mediawedge to my surprise also Euroscale coated is below
Fogra tolerances for primaries, max Delta E etc...
Avg Delta E ISOcoated vs. Euroscale Coated = 3.25
Avg Delta E ISOcoated vs EuropeISocoatedFogra27 = 1.06
Avg Delta E EuroscaleCoated vs EuropeISocoatedFogra27 = 2.98
But visually ISOcoated and Euroscale differ from each other quite
significantly when looking different images. So proofs made with ISOcoated
and Euroscale both can be inside Fogra tolerance even though pictures will
be quite different.
Also visually EuropeISocoatedFogra27 is much closer to Euroscale than
ISOcoated although that values from Mediawedge indicate otherwise.
what do you mean with "visually closer to Euroscale"? what is your
visual reference for Euroscale?
Any comments regarding these three profiles is appreciated

I also compared some FOGRA27 with its Characterization data using Graeme
Gills "profcheck" tool (
http://argyllcms.com/) but posted the results
only to the german list -- sorry.
You can find the results here:

The diameter of the bubbles is proportional to the Delta E 94 and ist
enlarged by factor 5 against a/b.
