Actually not exactly. Proofer gamut was bigger than ISOCoated v2 (especially in dark areas where problem mainly is /Process Black with higher "b" value, for example/, gamuts was displayed in Measure Tool), i am measuring ECI2002 Random, and compare with Fogra39. I do not suppose any out of gamut colors here, but maybe i am wrong?

Have You checked wither the problematic patches are in printer gamut or not? Refine procedure can't improve the result with out-of-gamut printer color.

Hi all,
My question is about profile tweaking with refine: what amount of
correction is possible to expect? My case: proofer system with Epson
Stylus Pro 4800, proofer profile created in Argyll, proof with ISOCoated
v2 as input profile (absolute colrimetric) give us results with few values with deltaE between 6-11. Abstract profile created with refine tool acc to manual and applied with both colprof and revfix, but i get nearly the same resluts as with original profile in both cases (deltaE differ in tenths). Maybe i am making some systematic error? (Argyll 1.3.5. in this case, but i get similar experience in the past with older version, but dont remeber
details).
Thank you for any advice,
all the best,
Kamil
