How do I convert a pdf from RGB to CMYK?

[foreignpresscomics]

I want to get my pdf printed, and I need it in CMYK. Is there a way to do that in Scribus? I know that in the export I can say that it is intended for the printer. Will that do it, or what else do I need to do?

Exporting with a printer destination will give you the PDF in CMYK, converting all colours in the process.
