Hello Darian, Chris and all other participants in this discussion,
I am really amazed about the lengthy discussion following my simple question!
Just to make it clear:
The discussion is not about the ECI CMYK profiles but about advantages (if any) of using
ECI-RGB in a workflow.
My original question (which came to my mind after a lot of testing) and which caused this
discussion was:
Could anyone explain to me in which workflow it could be advantageous to use the ECI-RGB
ICC profile?
So far I have not seen any positive (documented) replies to this question but I did see a
number of answers indicating that the use of ECI-RGB does not have real benefits .
I tend to agree with the following statements:
- Using ECI-RGB (compared to for instance Adobe RGB) does not bring any advantages in
terms of greybalance when converting from RGB to (ECI-)CMYK
- Using ECI-RGB (compared to for instance Adobe RGB) does not bring any advantages in
terms of other quality issues when converting from RGB to (ECI-)CMYK
- Converting scanned images (with included scanner profile) or digital camera images (with
included profile) to ECI- RGB only adds an extra step in the workflow without adding any
quality, so it is an unneccessary step.
So my question still stands out:
Could anyone explain to me in which workflow it could be advantageous to use the ECI-RGB
ICC profile?

Hi Florian,
From my experiences comparing to the Euroscale v2 profile, the ISO allows more saturated
colors, and has a more uniform greyscale. Where I see the main benefit, however, is that
the profiles and characterization data, together with the conditions in which each profile
was made, are easily available to all, allowing for many more people to speak the same
language. It has been very difficult, until now, to have 1 reference which everyone can
use. A couple of weeks ago I did a test and sent
the Altona Visual to three service bureaus for a Digital Cromalin using the Eurostandard
setting, and got three very different results. Also, until now, a web profile was
lacking, as was data for different paper types. For the printers, there have been
different results. Those who received files with no warning that the ISO standard was
being used had difficulties reaching the proof, while those who were told about the change
and were aware have been reaching it.
Best regards.
