It's been ages since I've had to send in a project in CMYK, 
PDFs in RGB with respective embedded profiles is the norm 
around here.
Occasionally my projects use spot colours, rarely more than 
one at a time; then I normally rely on the competences of 
the printshop people ;-)
Also been ages since I've had to send in a separate 
spot-colour sheet.

Just got back some print-on-demand photobooks; instead of 
using the dumbed-down windoze-only-crappy-cloudy-software I 
used Scribus to layout a very difficult mix of photos from 
various sources/ages (BW and color scans, negative and 
positive filmscans, orange tinted, blueish, yellowish 
etc...) with various types of RGB-profiles.
I'm even a bit surprised how exactly/correctly Scribus 
managed to display this mess on-screen comparing it to the 
final product (via 'Simulate printer'). But then; the 
printshop people were nice and pointed me to the correct 
output profile.

The only complaint I have for Scribus in this workflow is my 
inability to control the degree/strictness of out-of-gamut 
highlighting in the 'Simulate printer' feature. The feature 
would IMHO be of much more service to track real colour 
problems if the out-of-gamut noise could be lowered a bit.
