But then you need cmyk jpeg, which is not compatible (although
pdfTeX handles it)?

<quote src="http://www.faqs.org/faqs/jpeg-faq/part1/">
Adobe Photoshop and some other prepress-oriented applications
will produce four-channel CMYK JPEG files when asked to save a
JPEG from CMYK image mode.  Hardly anything that's not
prepress-savvy will cope with CMYK JPEGs (or any other CMYK
format for that matter).

If you really want cmyk, you need tiff.
