Hi
Been following this thread with interest.
So a few observations:
1) On making a profile from the Fogra 52 dataset, using ColorLogics
ColorAnt and CoPra4 software, reducing the TAC to 260% and applling heavy
GCR I get what seems to be a usable profile when tested using the stadard
test images, Grainer Rainbow, etc.
2) However it is noticable when separating RGB B/W images that the CMY
separations are not neutral, there are blue /black as reported by Martin.
If these are printed correctly would this be an issue? Hope not! The
yellow separation, as reported by Martin is a little odd.
3) Soft proofing on screen seems to be a issue with M1 based profile with
higher OBA¹s. I guess as the screen cannot show the OBA as the human eye
would see then, is shows the paper white, say -b10, as very blue. Not sure
this can be easier corrected?
4) Is Is there spectral data for Fogra52 as there is for 51?
Regards
Paul Sherfield
