Hi Jo et al,
In our vision (we're magazine publishers) we ideally want all our images,
which come from more and more different digital sources, to be delivered to
us in the largest possible colourspace, so when shot with a digital camera
we want the camera's profile attached as a source profile, and we ask our
lithographers to attach their scanners profile.
We do so for the following reasons:
less conversions leads to less quality loss
we want to be able to reuse the images now with different media, and in
future we might see the print colourspace expand, and we don't want to lose
colours we'll be wanting later.
As for the point of not being able to assess the final products colour:
that's why Adobe gave us softproofing, both in InDesign and in Photoshop, so
our designers can choose to either look at the 'digital slide'
representation of an image, using the source profile, on a calibrated
monitor, or to look at the print preview using the print profile.
I must add that this workflow is a pain when using Quark Xpress 4 (and we're
still a long way from a total switch to InDesign...)
To sum it up: The less conversions the better, use a sensible source
profile, and let colourmanagement work its magic

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.
Darrian
