[XeTeX] Outputing PDFs in CMYK ColorSpace

[Clinton Gormley]

Hi all

I'm producing PDFs with xelatex destined to be printed in a newspaper.
The printers require the PDFs to use a CMYK colorspace, but I can't find
any option to set this.

The only solution I've come across is the one mentioned in:

$ pdftops -level1sep original.pdf separated.ps
$ ps2pdf14 separated.ps

Is this still the best solution?

thanks

Clint
