For some reason I can no longer export .pdf files from Illustrator and Indesign in CMYK color modes. That is, the file will export, but it always ends up as an RGB file. I've tried exporting the file using the PDF/X 1a preset with the same result. I've also tested saving my files in Illustrator to a .pdf file and those are always saved with the same working RGB color profile.
Does anyone know why this would happen and what I can do so I can create CMYK PDF files again? This is driving me crazy and I need to send art (created in InDesign) to the printer in CMYK colorspace.
I am working on a Mac. My operating system is OSX version 10.6.8. Thanks!
