I designed a brochure for a client in Xara Pro and then exported as a PDF for commercial printing. Advanced options lists color space as CMYK. When my client took it to the printer, he was told it was RGB and they had to charge him extra to convert it to CMYK.

My question is did I neglect to do something? And I have to admit I have no idea how to check whether it's CMYK or RGB ... suggestions/help would be appreciated.
