Is your conclusion that the information from Adobe isn't right and that the

19% and for uncoated paper is about 25%.
I cant find a good explanation in the book wy their is such a big difference
between the Photoshop's Custom CMYK standard settings and the Euroscale 2
profiles. The only two things I find in the book are that the way dot gain
compensation is calculated is changed (but in what way?) and that the old
and the new ink definitions for coated and uncoated paper aren't the shame.
Short answer. The old Photoshop CMYK Setups were presumably based on
something, but no-one currently involved with Photoshop development
can remember what -- they date from the early '90s. The v2 profiles
are based on published FOGRA data. There's basically no relationship
between the two.
Versions of Photoshop prior to 5 had a bug in the way dot gain
compensation was calculated, but that's totally unrelated to the v2
profiles....
