Summary0005139: CMYK Spots don't display the same as pure CMYK with color management.
DescriptionI'm using spot colors and the same color set as spot and non-spot (cmyk representation) doesn't show up the same.

Color in question is C20, M4, Y100, K32. I guess it's the same about all colors, but this one in questions is vastly different.

I forgot to say the RGB approximation is R156,G154, B0, and it looks mostly the same when I use pure CMYK.

Spot color are normally not color managed during the printing process, but displaying them is another issue. I will provide a better conversion for thes colors. No gamuck check nor output simulation on screen will be performed tho, for the reason mentionned above

Yes, I know they are unmanaged and whatever shows up on screen is irrelevant to what will come out, but I still like to have it show up correctly if I have the CMYK at hand.

Spot colors conversion are now handled as follow:
- conversion to RGB is done according to color management prefs and takes into account monitor profile
- no gamut check nor printer simulation is performed
