So, I'm trying out Scribus (1.4.8 on Win 10) for a project. I've installed and am using SWOP v2 ICC for color management in this project.

My question is when it converts this book to a PDF/X3 could I have problems if one or more images in the Scribus doc are not CMKY? In other words, will it convert the images to CMKY within the new PDF or am I setting myself up for a headache?

I understand that not all RGB colors translate to CMKY (like some blues and some reds) but I don't know how to tell if any of the colors in these files will not convert. I'd like to be able to identify that before it becomes an issue.

  • Have you tried simply preflighting a PDF to check?

  • @Scott No, I'm in the beginning stage of the project, just trying to be forward-thinking from the start.

    @Leezard - I think you should probably convert the images to CMYK, if you want to be forward thinking from the start. Why take the chance? If you are looking for free software to convert RGB to CMYK, then Krita can do it. Then at least you can check if there are any weird colour changes.

When you activate the color management, you can ask Scribus to simulate the printer on the screen (and you can activate the option at any time after that : - ).

You can also ask Scribus to mark out of gamut colors (by default they will be show as bright green).

Concerning the PDF, if you don't have access to professional pre-press tools your best bet is probably to trust Scribus and -- if in doubt -- ask the print shop for a proof. All other actions will probably result in a lost of time for you.
