Hi Nermander!
Thanks for the quick and helpful answer. It is good to know that if you choose "Printer", it will choose the CMYK mode.
In the meantime the Color Options of the PDF have changed as Scribus has progressed and there are more options to choose. What do you suggest regarding the use of Color Profiles? And which one to choose?
The printshop I will use, recommended the profile "ISO Coated v2 300%", but I can only choose it for the CMYK images in the document setup/color managment (but not in the pdf-save-window) and I set it accordingly. Will this profile be used when I check "use color profile" in the save-as-pdf-window?
What is meant with solid colors? Is a Color profile needed for this, too?
Thanks for your patience as I am new with this part of scribus. I only used Web/Screen so far.
