Indeed, always insightful to get an explanation from Hal! :-)

What fileformat are you using? PS native (PSD)? Or tiff?

Also, can you use ICC profiles elsewhere?

Scribus can simulate printer colors in Preview, version 1.3.4 also on

Color management is primarily about using defined colours and secondly about
translating between gamuts. A printer's gamut will always be different to a
monitors gamut, so you will need experience and/or color proofs to get the
colors right. Working in a high gamut color space will offer colors to you
which don't work on printer, but all colors which *are* in the printer's
gamut should appear exactly the same on screen. 

Working in the printer's color space will make it more difficult to switch
the printer if needed. It's better to allow Scribus to apply the printer's
profile on export (or even embed the used profiles in the PDF and let the
printer do the conversion if they support it, as in PDF-X3).
