It's RGB.

The printer is also RGB.

Yes, that's true -- but then what am I going to do with a profile 
based on GIMP output and not on output coming from Scribus?
I've been told that it is most critical not to change the 
workflow *at all* once the profile being made. Please correct me 
if I'm wrong, and excuse my ignorance.
As far as the GIMP is concerned, I don't see the possibility to 
use an ICC printer profile with it yet.

in brief, the advice is as follows:
- open the test chart in Photoshop
- switch off any color corrections in the printer driver
- select the paper type (usually a matte paper)
- in the color management section, set the "output color space" 
to "Same as source" (usually Adobe RGB or sRGB)
- print the file
- have the printout measured
- once you have got the profile, set "output color space" to this 
profile and leave the printer driver as it were, with color 
corrections switched off.

So I was wondering if this would work in Scribus as well:
- printing a test chart from Scribus with color management 
switched off to get something like a "raw", unbiased output from 
the printer
- measuring the printout and making the profile
- using this profile in Scribus with color management turned on 
again, selcting this profile as printer profile

Thanks for any advice,
