Thanks to everyone who replied to my post. In addition to the
helpful info provided, I've also searched the Scribus archive
and found the following post


which highly recommends using Krita for RGB->CMYK conversion.
I've tried it out myself and can confirm everything that was
said in that post. Even so, since all my images are originally
in RGB, I think I'll stick to importing them direclty into
Scribus and letting Scribus do all the work.
