Anoto Live Forms PrintProcessor - Why does printProcessor alter the colours of a CMY only form?

Question
Why does printProcessor alter the colours of a CMY only form? My understanding is that the printProcessor will only convert any K elements of a form into their nearest CMY equivalent. It therefore shouldn’t alter any existing CMY only colours.

Answer
This happens if the original PDF is saved as RGB and that confuses the Paper SDK when converting. Re-save the PDF as CMYK and everything will work as it should.
