1.) Dan Margulis' comments refer to the old, deprecated Custom CMYK
feature, not to any of the v2 profiles.
2.) The Euroscale v2 profiles were built from published FOGRA data.
If your press conditions conform to that data, the profiles work
extremely well. If they don't, the profiles will not work well. It
is nonsensical to complain about "profile errors" when your press
conditions don't match the conditions the profiles were built to
describe...

I've got into troubles with Photoshop 6 / 7 separations, and have read
things
like
"Dan Margulis recently posted that this too-high cyan value was a *last
minute kludge* implemented ........"
"...Hit the curves button and you'll see that, whatever you choose as
your
dot
gain percentage, PS adds 4 per cent to the cyan......."
Could someone tell me the right way to
1- convert RGB images to CMYK in Photoshop without getting a cyan or
green
color cast on press?
2- convert archived Euroscale v2 CMYK images to well balanced CMYK Euro
standard files?
hello,
European profiles from Adobe are often coming with errors.
Yes, I think like Dan margulis that the Adobe Euro V2 is with too much
important correction on the magenta ink. The result is a green color
cast and poor magenta and red colors.
The best way to obtaint good colors is to use the ECIRGB profile for
the RGB space and a CMYK profil simulating a Cromalin.
The more easy to do that is to use the "Eurostandard coated" from the
Photoshop Version 5.
But this one have also a error with a dot gain of 10. You have to put
the dot gain at 18.
When you do that, it is normal that the manual curve adds 4 per cent to
the cyan. It's the normal correction to have a good gray balance.
I suggest also to correct the separation table with light black
generation, maximum black at 90 and total ink at 340.
If you want a V2 CMYK profile, you may use the "Pantone Euroscale
positive" from Pantone. it is a good profile for an European defauld
CMYK space. His gray balance is not absolutly neutral, but with a very
little green color cast.
