Heard that before. Well it's just a private production, so there's no
need to be perfect, but the result at the moment is not really satisfying.
Well, i have some time left, so I am ready to get deeper into the topic.
But from the statement, that I should not use embedded profiles I
thought, that this is not the direction I should run to.
Maybe I am wrong, I am new to this topic. Maybe I can use profile
while converting, but don't embed the profile into the resulting PDF?
I uploaded a PDF with the settings mention bellow and only got a warning:
Warnung: In Ihrem Dokument werden ICC-basierende Farbräume verwendet.
~Warning: Your document uses ICC-based color-spaces.
So since the resulting pdf looks much better, I might ignore this
warning and print it that way anyway, we'll see. Maybe we'll also find
a better solution.

Done, it was off up until now. So the test-print (PDF) was produced
without color managment turned on.
I guess this is bad :-)

Yes, you're right. On their website they recommend ISOcoated_v2.
RGB- zu CMYK-Daten, ICC Profile)
On the other hand I should not embedd ICC profiles. That troubles me a bit.

Ok, i turned Color Managment on, but i can't choose between profiles.
All drop down boxes just contain one alternative (plus the empty
I'll search the wiki on how to get and install these profiles.
I produced an pdf with the following settings:
and the result looks much better! I now got a warning (see above).
I'll try to do the same process with the correct profiles.

Adobe Reader 8 on Linux. Profiles in Scribus: None, color management
Thanks for your hints so far
