PDF CMYK Problem

[Newbietoo]

Hi,

I am using Xtreme Pro V4 and am exporting to PDF to provide print-ready CMYK

When I print direct from Xara the colour is pretty well a perfect match to the hard copy CMYK colour chart I have. However when I export the drawing as a PDF/X an then print, the colours are way off. I've fiddled with just about every setting in the PDF export dialog (none of which I understand) except they all say CMYK, but to no avail.

I have attached screen shots showing the difference between Xara and the PDF. The printed version of the PDF looks the same as the screen version (and is wrong). The screen version of Xara is quite different to the printed version (of course), but the printed version is true CMYK

What am I doing wrong?

Thanks
Patrick
