When pdf target is set to "Printer" and "Use ICC Profiles" checkboxes are not
checked the pdf will be created with DeviceCMYK color space (open the pdf in
a text editor or podofobrowser and check yourself). If a checkbox for "Use
ICC Profiles" is checked then the color space will be ICCBased and colors
will have their current icc profile embedded in the pdf for output device to
be able to convert the colors to it's own color space.
So if you have the correct printer profile already when creating the pdf I
don't see any need for "Use ICC Profiles" since the pdf color space will be
already correct for the target printer. If you know that your printer's setup
can handle embedded profiles then there's no harm in using this option. There
was a semi serious bug (http://bugs.scribus.net/view.php?id=5416) related to
this which was fixed 10 or so minutes ago. So you may want to wait till the
anoncvs is synced and try yourself.
A test pdf with DeviceCMYK color space can be seen at
http://www.saunalahti.fi/rikle/cmyk-test-fixed.pdf There are three images on
the pdf the top most one is converted to cmyk in PS middle one in Krita and
the last one has been converted by Scribus (was a RGB image when imported to
Scribus). All conversions were made with similar setup using ECI ISO Coated
