GIMP and Inkscape can't do CMYK,
Does this not do it for Gimp?

The point of CMYK is that you create stuff in the appopriate colours:
My printing recommends the following:
* Black text: 100%K, 0% all others
* Black backgrounds: 100%K, 30%C, 0% others
RGB gets converted to CMY(Cyan, Magenta, Yellow)(with no K(Black)
channel).
This leads to imperfect blacks in printing, and 3x the ink being
dumped to form black leads to smearing, drying issues etc.
Text ends up with fuzzy colour speckles around it too.
The GIMP plugin will not resolve these issues as every part of the
image would have to be hand tuned after being created, which is
really
not practical.
GIMP does CMYK natively now:
http://en.wikipedia.org/wiki/The_gimp#Color_support
Citing that exact link:
"...GIMP does not have any built-in support for CMYK mixtures that
cannot be represented in RGB, such as rich blacks, though they can be
simulated to a limited extent with third-party add-ons."
I wouldn't call that "CMYK natively" - I'd consider that partial
implementation. They really need to offer a CMYK editing mode
completely divorced of Gimp's RGB heritage.
