Ok so far no problem, since i thought > after printing it looks the same or at least similar as on screen. You probably want to look a bit deeper into color management. It's non-trivial to get right. Getting colors to look on screen as on paper is very difficult and requires a lot of consideration (e.g. correct monitor calibration and profile, correct printer profile etc.) Key issues: - Enable color management in Scribus. - Ask your printing company about the profile they use. They'll probably tell you "Euroskala" (which is Euroscale Coated) or "ISOCoated". - Use that profile in Scribus, so it will convert RGB colors correctly. - Remember that RGB contains colors which cannot be represented in CMYK and vice versa! > Well, but it doesn't.

Which viewer did you use to get these pictures? What CMYK profile did you use? What RGB profile?
