It's time for the old CMYK talk again. Did the obvious search but can find what I'm looking for.

Sent something to the printers. But the complained that the text was 'rich black' i.e. not black but made from all colours.

Followed the advice of exporting in pdf/x. But they said that did not work.

Reading the post it seems XXPro is not fully CMYK complient - is this one thing wew fall down on?
