I assume that PrinceXML does not support spot colors as reading and researching the forum.

However SVG 1.2 supports "named colors" which could used to use spot colors through the back door on the SVG level:

Does PrinceXML support SVG 1.2 (especially "named colors")?

Prince supports a subset of SVG, and does not support named colors yet.

Now we have released Prince 8.1, with support for named spot colors using a new @prince-color CSS rule. Documentation will be available soon.
