Document background fades when exported to PDF
I've created an InDesign document with a dark blue background (check linked photos), set to CMYK. When I try to export the document to PDF (note: i have tried every possible setting) the background colour fades, as if it was set to RGB - even though I have made sure to set everything as CMYK. I have tried to export it with press quality, highest quality, different versions and you name it - and nothing seems to work.
How can I fix this?
Thanks,
Ebba
