Excellent question. Don't know the answer. But I do know that when I
use pdf x/1-a format (Scribus 1.5.0) I don't have problems with RGB.
Of course all the other factors must be set correctly.
For members of this group only, if you have an sla file you want saved
as PDF X/1-a please send it to sales at wexfordpress.com subject
"scribus conversion." For now I'll do this for free. We may have to
wait a year for 1.6.0.
