Summary0015333: Color separation : print preview doesn't display spot colors
DescriptionI'm working on a document which uses a Pantone spot color (5 colors in total : CMYK + spot color).
When I check the color separations in the print preview, I can see CMYK colors just fine, but not the spot color.

I've joined a sample and a few screenshots.
The spot color is the brownish one.

ton_direct_color_config.png : spot color configuration
ton_direct_edit.png : preview of the document
ton_direct_preview_cmjn : color separation for CMYK colors
ton_direct_preview_pantone : color separation for the spot color

I've worked on this document for a few years now, and the color separation worked juste fine previously (that is 3 years ago on Scribus 1.5-trunk).
I also recall I could see the spot color in the print preview.

Now I don't know if this is just a preview bug, or a more serious bug affecting the color separation for spot colors.
Should I be worried that the color separation will fail when we'll send the document for printing ?

Hi tcharlss

I noticed that a setting is not good, please you modify:
File menu -- Document setup (or preferences... too) -- Colour management -- RGB images and RGB solid colour rows include wrong settings.

Let it be: sRGB profile and not the Monitor profile !!!

Avoid using special characters inside spot color names. Limit yourself to alphanumeric characters, spaces and underscores.

Thank you very much, I changed the color name and that solved the problem.

I think there should be a warning of some sort if spot color names must follow a specific convention, which doesn't seem to be the case for regular colors.

Also @PeterBenedek thanks for the advice.
