I've been playing with LittleCMS' icclink. It's a rather long single
string but here's the command I've executed for sRGB to GRACoL 2006 1v4
using black point compensation, relative colormetric, high resolution.
The -f2 preserves the black plane which for sRGB to CMYK doesn't really
apply.:
icclink -o
C:\Windows\system32\spool\drivers\color\sRGB_to_GRACoL2006_1v4_dvl.icc
- -d"sRGB to GRACoL 2006 1v4 BPC RelCol DVL" -t1 -c2 -b -f2
C:\windows\system32\spool\drivers\color\sRGB.icm
C:\windows\system32\spool\drivers\color\GRACoL2006_1v4.icc
On the Mac it would essentially be:
icclink -o /Library/ColorSync/Profiles/sRGB_to_GRACoL2006_1v4_dvl.icc
- -d"sRGB to GRACoL 2006 1v4 BPC RelCol DVL" -t1 -c2 -b -f2
/Library/ColorSync/Profiles/sRGB.icm
/Library/ColorSync/Profiles/GRACoL2006_1v4.icc
It seems to work well. But then again I'm no color expert...
