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
- 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,
