Hi Todd
I doubt that the delta H is used for average CMY Gray if
one uses the Fogra Mediawedge 3.0.
It is. See

Hi Klaus
I feel your pain! The Idealliance, GRACoL & SWOP stuff is poorly
organized to say the least. However, I think the data sets you are
looking for (in CGATS format) are available at:
http://www.gracol.org/resources/datasetdownload.asp
Regarding tolerances: Ha! I threw a fit/rant about this same thing
back in April
[http://lists.apple.com/archives/colorsync-users/2008/Apr/msg00319.html
].
There are NO official published tolerances that you can use "if one
simply wants to know which patches have to meet which criteria". This
doesn't exist for SWOP or GRACoL! Amazing but true. Personally when
I'm "certifying" a proof to be compliant to a SWOP or GRACoL dataset,
I use the ISO 12647-7 tolerances, which I believe are:
delta E paper: 3
delta E average: 3
delta E max: 6
delta E primaries: 5
delta H primaries: 2.5
delta H avg. CMY gray: 1.5
