Reply To: CID 2 fonts

PDF/X 1a looks is a pretty old specification. I believe they are up PDF/X 5+ now. Are you worried about backwards compatibility with old acrobat software? Or just having the printed version come out differently?

I'd try one of the newer specifications, PDF/X 3 maybe, and if you still get errors/warnings, just convert fonts to outlines. I've seen some debate about converting test to outlines but it really is the safest thing, and it especially makes sense if the amount of text is small and you're mostly talking about large fancy header fonts (vs plain body copy). Don't stop using nice-looking fonts :) I save my .indd file first, then outline everything, export to PDF, and close without saving. That way the indesign file remains editable later if you decide there's a problem with the PDF.
