Hello everyone,
Just following up on Standards development related to ICC CMYK Reference
Conditions for US Sheetfed printing. For Web, we have SWOP. SWOP Inc. does
not want to release a SWOP-sanctified TR-001 derived profile, so they send
us to Steve Upton's Chromix site. That's fine. Or we have to create our own
if we have access to the TR-001 data and use an CMS that supports the
IT8.7/3 Target format (PrintOpen, ColorBlind, Monaco (not sure?), Kodak
ColorFlow, ProfileMaker and ColorTune). -- Please add to the list if I have
forgotten any.
What about for SheetFed? Last time I checked, a GraCol colorimetric standard
was in the works. I am not aware of any CGATS Sheetfed-related activities.
And the other that comes to mind, which I wonder where it stands today is
GATF's own SHoPS.
OK. So suppose someone, today, only has a TR-001 profile, how good would
this profile be as a predictor of US SheetFed printing conditions? Granted,
If one increases the TIL too 320% or even 340%, the L* range is going to get
closer to a Sheetfed press but what about the CMYK primaries? I believe
that the SWOP Cyan, for instance, will understimate a Sheetfed Cyan -- less
Chroma at least, because of less density and possibly different L* and H*
angle.
Just trying to kee up to date. I do not have a chance to go to all those
meetings.
