Hello Andrew,
The fact that certain users do not even know that Photoshop color settings
exist, or know how to use them, is obviously a problem, and something we
both agree can easily be solved by reading the manual, or, like it was
mentioned by Martin Weberg, by having the printer or prepress shop
communicate their color management policy to their customers.
Still, this gives me part of the answer I was looking for, that many
designers, all over the world, will simply work in SWOP v2 by default when
selecting a CMYK color space. This is certainly not an ideal situation as
you point out with your example of a Canon Matte profile on an Epson printer
loaded with Luster paper, but the press world is somewhat more uniform than
the ink-jet printer world. I said part of the answer because I am also
interested in knowing what are the choices by those who know how to do color
management.
What I seek in these default CMYK spaces is similar to what we often see as
RGB recommendations: sRGB for Web work (a Photoshop default), Adobe RGB for
prepress (another Photoshop default) and general photography, or even
ProPhoto 16-bit for large gamut work. I know these choices are debatable and
may be different in Europe, but they cover a large number of cases, and
nothing prevents anybody to use a more specific RGB space for their own
work, as you well know.
So far I saw a definite preference for Fogra39 in Europe. I have not seen
such a clear stance for North-America yet, and I am very tempted to consider
the current Photoshop default (U.S. Web Coated (SWOP) v2) as the best of the
less than ideal CMYK working spaces in this part of the world.

He can, Adobe his is favorite whipping boy <g> Of course, RTFM is the
most sensible suggestion.
However, because of the importance of color standards, it would be a
nice suggestion to Adobe to add a small configuration screen (a wizard)
when installing asking (and suggesting) the most appropriate color
settings.
In the Color Settings, if you hover over any of the settings, including
the current CMYK profile (in the case of U.S. Web Coated (SWOP) v2 ) it
tells you all about what the target aims are for this profile (“quality
seps using US Inks with the following print conditions...”).
Peter Nagy also mentioned many will supply work done in SWOP.
Even users printing to a Sheetfed press <g>. You either have users that
have a clue about the target printing conditions or they don’t.
Can you imagine if everyone printing to a Epson printer on Luster paper
just assumed all ink jet printers were Canon i9000 using Matt paper? Its
about that bad in the CMYK world for those that simply have no idea how
highly device dependent CMYK is and how they really need to target the
conversions to the printing process. There isn’t a thing Adobe can do
about this.
Any of the preset color settings that begin with North America set the
CMYK profile to U.S. Web Coated (SWOP) v2 unless you pick newsprint which
selects SNAP 2007 which kind of makes sense. There’s a number of other
settings for other countries which alter the CMYK profile. None may be
the correct profile of course.
When the optional brain probe for CS6 comes along, Photoshop will be able
to read your mind. Until then, users have to take responsibly for setting
the correct profile in the Color Settings or when using the Convert to
Profile command and unless they know what to select, any default or other
setting is a giant crap shoot.
