Dear Mr. Karl Koch,
Having been involved in the ECI profiling activities for offset and being a promotor of
international standards I take the freedom to react to your message.
The profiles from ECI, based on the ISO standard are well accepted in several countries
including our own country.
The introduction of these profiles has greatly improved the standardisation process and
the quality of offset printing in our country.
If there is room for improvement, as you suggest, I would highly appreciate if you would
put efforts in improving the profiles published by ECI. Of course I can imagine it is
always possible to improve workflows, settings and profiles..
I guess that, because you are a member of ECI yourself it should be possible to achieve
the suggested improvements from within this organisation. That would be for the benefit of
the entire printing world and would help to further enforce the standardisation process at
least in Europe.
Best regards,
Jo Brunenberg

Claas, Vitor, Emmanuel,
sorry, Claas, it´s not just a matter of taste. The ISOcoated_v2_eci profile is faulty as
you can see when you convert (e.g.) the test image Test Out-of-Gamut colors.tif (1,2 MB)
from
http://colormanagement.org/en/testimages.html to ISOcoated_v2_eci and to
ISOcoated_v2_bas.
There are JPEG artefacts in the image (headband, skin tones) which will be
"enhanced" with ISOcoated_v2_eci. The reason lies in "jagged" gamut
boundary in this profile (there are other flaws as well).
You can download (from
www.basiccolor.de) and try "basICCoolTool profile´s
secret" to see the differences.
And no, the eci profile is not an official one and is not ISO! The basICColor profile was
made fromthe exact same characterization data from Fogra. And these are not ISO either!
ISO just specifies the printing condition – color values of the primary colors and dot
gains.
I do not want to diminish the achievements of the eci (being a member myself), I just
want to make clear that there are more ways than one and the user is free to choose the
one he likes best.
Best regards,
Karl Koch
