The issue isn't that the same colors defining spot colors do not hit a pdf. They do. But spot colors in Xara applications are only truly useful if you use them as spot colors...then it is the reference that matters not the colors displayed.

The issue is spot colors use wrong definitions to begin with. And here's the, my, main gripe. They can never be transformed to correctly defined color values depending upon an output condition because there is no color management.

Again, because Xara applications have no internal, user-configurable document color model reference (both for CMYK & RGB), no document color management, Xara applications do not know what to do, how to transform, spot color definitions. Period. Compounding this spot color transformation is the fact that without using a LAB color definition, spot colors defined in CMYK cannot ever be properly transformed into the proper colors if CMYK output is desired. RGB spot color definitions are a bit better in this regard, but still cannot be properly characterized by "dumb" numbers that have no concept of both the document color space and the eventual output profile.

Professional applications use color management, use LAB spot color models and transform those colors properly.
