I understand your point.
I don't understand why it should be the case however. It should be possible
to get fairly close to the result of Euroscale v2 using the custom CMYK
dialog. Certainly the tools are cruder than those used to generate the Euro
v2 profile, so I'm not expecting a perfect match :-)
But what we get is a result that shares little resemblance with the result
of the Euro v2 profile.
This should be fixed.
Photoshop is not supplied with a profile that is suitable for creating CMYK
images for reproduction in the majority of European publications.
People who need to supply CMYK for European web presses will be tempted to
build their own custom profile and will get a very poor result for their
labours, or waste a lot of time and materials fudging the settings until
they get something that looks OK.
Adobe people in this forum state that they have received no complaints about
this. Perhaps this is because those that are able to fix the problems do so,
and those that aren't suffer the complaints of clients and the smirks of
repro guys in silence.

Which brings us back to the original point. The Euroscale profile only works
for me to a limited extent.
If you examine the Euro v2 profile and compare it to ISOcoatedsb in your
favourite profile editor - what do you see?
In PrintOpen I see groups of data points that suggest that the same source
data was used. But I also see that the Euro v2 profile is has a pronounced
shift to cyan, some funny stuff going on with gray balance and some monkey
business in the shadows.
I have no idea what this stuff means as my interest is in separating the
images and proofing the results - not editing other people's profiles.
But I am deeply suspicious of the fact that the results of separations made
from AdobRGB1998 tend to produce reds that are too saturated and skin that
is too warm and that Euroscale v2 produces CMYK that is too cool.
Using the two profiles produces a passable result.
If I see somebody claim that Adobe have fudged the profile by chucking in a
couple of points of cyan and you stating that this is not true - I'd like to
hear your views on a direct comparison of the two profiles.
