Title: [SOLVED] ICC Profiles on Scribus : how to install new ones ?
Post by: omblik on February 14, 2025, 06:58:40 PM
Looking at the Scribus's archives, my question is an old song for this forum... However I haven't found the solution in spite of my numerous researches on the big Internet.

I use Scribus for the first time. I do the imposition for a fanzine I want to print in risography. For this I have to use special ICC profiles and it would be super convenient if Scribus could get to them.

I have a Windows 10 computer and the latest Scribus version (as I am a newcomer to this software). I have already installed the ICC profiles on C:\WINDOWS\System32\spool\drivers\color  for the first part of my job and softwares as Krita or Photoshop can read them and access to them.

However, I can't find a way to access to them on Scribus. I've already tried :
- no document opened :
Settings -> Colour Management -> Activate Colour Management -> looking for my profiles in all menu list... won't find them
Settings -> Paths -> Colour Profiles -> set C:\WINDOWS\System32\spool\drivers\color  as a colour profile path, then returning to Colour Mangement -> won't find my profile in the menu list...
- same with an opened document.

Can someone help me ?

in the preferences, you have a section called paths...

something is waiting for you there : - )

(you will probably need to restart scribus after having changed the values in there...)

Hello,

Thank you for your answer !

As I have said in my first post, I've already set  C:\WINDOWS\System32\spool\drivers\color as a path for the Colour Profiles. I have restarted Scribus after this and I haven't found the ICCs of this path in the menu of "Colour Profile" after this. Maybe there is something really obvious that I don't understand ?

In what menu can I find those profiles after having set the path ?

For example in Photoshop you cannot find them in the section "Colors" but you have to select "Convert to  profile" in the Edit section. Maybe there is something analog in Scribus that I haven't found ?

Hi,

Could you upload some of these ICC profiles somewhere and paste the link here ? Due to the specific printing process, I suspect these profiles are N-Channel profiles which are not supported by Scribus.

Hi,

With pleasure ! I began to have this guess too yesterday night.

Here (https://colorshift.theretherenow.com/profiles) is the link for the open-source ICC profiles I use for separation of colors for my files.

I guess you're right and the solution will simply be to do separation of colors for each a5 file I have to print in a big a3 for riso, and do the imposition after.

I am not an expert on color management, but those profiles look like what I would call "spot color profiles".

If you are using spot colors, I think you do not need a profile, you just need to define the spot colors in Scribus.

I had a look and most of these profiles are either N-Channel profiles or RGB printer profiles. As previously mentioned, the first kind, ie N-Channel profiles, are not supported by Scribus. The second kind is not supported either. They are profiles which are most commonly used in Windows environment where the system sends data in RGB colorspace to the printer and the printer hardware performs the separation itself.

Thank you for your time and the clear answers !

I will split my colours before the imposition on Scribus, then.

The thread is resolved I think.
