Hi Darrian,
Thanks a lot for all the info.
I recently heard about a similar test in the Netherlands.
Hope, that I correctly remember the case: Three printers were asked to
print the same content according to the ISO standard - all three
results were very close to each other - much closer than in the past
when every printer provided very different results. Of course all of
them claimed to provide the best possible solution ;-)
Best regards,
Florian

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.

Asunto:Re: [ECI-EN] ECI-RGB / Any advantages?
Hello Darrian,
Good points, Thanks.
- yes we calibrate our displays to Gamma 1.8
And therefore have the same situation as you have with Gamma 2.2 and
profiles based on the same Gamma. As long as no switching from/to
'your' and 'our' workflow is needed both of us are just fine.
The common settings not only in our workflow are D50 and Gamma 1.8.
Based on visual comparison with proofs under D50 one sometimes
slightly changes the white point to 5500 K but never changes the
Gamma.
At that point it seems to be an issue of what's common and *not* a
technical issue based on quality aspects.
At least in Germany ECI RGB is very common - many image data bases use
this color gamut as reference and the ECI (European Color Initiative)
recommends using ECI-RGB in two cookbooks about pdf-workflows
(pdf/x-1a and pdf/x-3).
But there is another point you raised that makes me very curious to
hear more about your experiences with the ISO profiles. What kind of
quality increase did you see using the ISO profiles? Did you print
seps already? What kind of experiences did the printers have as e.g.
the dot gain is significantly lower.
Looking forward to learning more ...
Best Regards,
Florian
