Hey, I already did some PR for this application at graphicsplanet.org (http://www.graphicsplanet.org/) and Libre Graphics World (http://libregraphicsworld.org), but presumably not everyone visits them, so here goes... :)

As many/all of you know GIMP doesn't have real native CMYK support. Some years ago Alastair M. Robinson wrote a plug-in for GIMP that did ICC profiles based CMYK separation. The project was then picked by Yoshinori Yamakawa renamed to separate+ (http://cue.yellowmagic.info/softwares/separate-plus/index.html) and continually improved.

So now Alastair revisited the old plug-in and created a new standalone application out of it called CMYKTool (http://www.blackfiveimaging.co.uk/index.php?article=02Software%2F05CMYKTool).

What you can do with it, more or less, is:


freely convert between RGB and CMYK using ICC profiles (uncluding devicelink profiles)
view and compare (with synced navigation) versions of converted image in 1:1 and fit to window (right-click) modes
create conversion presets
view per-channel % and overal ink coverage for pixels under mouse cursor
save to TIFF (8/16 bit per channel) and JPEG


There's a number of plans for future listed here (http://www.blackfiveimaging.co.uk/index.php?article=02Software%2F05CMYKTool%2FCMYKTo ol+0.1.1+Released). Alastair is very responsive. Some of the new stuff and bugfixes is a result of his interaction with linuxgraphics.ru community. So if you don't like lack of interactivity in the separate/separate+ plug-ins, CMYKTool could do the job for you.

Cool!
I've used the separate+ plugin a few times for doing print material and it really helped me.
This standalone seems like a very useful tool.
