Dear List,
Recently there was a lot of discussion on the ECI List (mainly German
section) on the Adobe profiles and the quality of the rendering.
Peter Constable of Adobe asked on the Adobe Pre Release Forum several
questions regarding this issue.
I would like to copy Peter's questions on this list and ask you to comment
on this and a copy to Peter directly.
This could improve Adobe's satisfaction index and help us to increase the
usage of ISO profiles.
Regards, Henk Gianotten

Hi Henk,
Your Question #1 - "When does Adobe deliver the ECI-profiles as part of
their standard profile package in CS2?"
We currently are trying to support the FOGRA data sets that seem relevant
for our users. We looked into supplying the ECI profiles during out
development of the Adobe FOGRA27 profile but there were several issues that
we could not resolve. These were comments I posted on the Adobe
Pre-release forum as reasons for creating our own profiles:
*************
1 - Adobe gamut mapping is very smooth. During testing of non-Adobe
profiles, we noticed some poor smoothness of perceptual mapping in certain
areas of the color gamut.
2 - Perceptual gamut mapping of Adobe profiles are consistent with gamut
mapping of many commonly used press profiling applications. This leads to
better consistency in workflows. We noticed that the ECI profiles'
perceptual mapping was significantly different than the perceptual mapping
of our current set of profiles (lighter in the mid-tones).
Question: Is this a preferred perceptual mapping in the EU compared to the
Gretag/Adobe type rendering?.
3 - User's are aware of Adobe's gamut mapping strategies (they're in our
other profiles). The new (Adobe) Europe FOGRA27 profile shares these traits
reducing unexpected surprises when separations are reviewed.
4 - We are not required to license Heidelberg's IP to distribute the profile.
5 - ECI's profile creates a very long black starting at 0%. We have been
told that users like to see "cleaner" highlight color without K. Our black
starts at 30% of total ink.
*************
Henk - I would appreciate feed-back from the ECI members on these 5 points
above.
We would be interested in shipping third party profiles if we could make
headway on the 5 issues mentioned above.
Your Question #2 - "Why did Adobe deliver only 2 profiles based on the ISO
standards and not all 6 different versions?"
Which profiles & ISO standards are you referring to? Several of our
profiles refer to older FOGRA data using ISO 12647-2:1996 (Euroscale Coated
& Uncoated) and FOGRA27 which references ISO 12647-2:2004. Our Japan Color
profiles also use ISO 12647 type printing. Others, like the SWOP profile,
reference ISO-based ink.
I think your question is, "Why hasn't Adobe supported the other "major"
FOGRA characterizations?"? We are looking at doing that.
