How exactly do you export from InDesign to PDF? Which version of InDesign are you using? You should not have to use Acrobat to get from InDesign to PDF - InDesign can export to PDF directly, and this way, nothing else will interfere with what goes into the PDF file.
I do export from InDesign, and then it goes to Export Adobe PDF. I tried all different set ups. I have it on PDF/X-4:2010 and Compatibility: Acrobat 7(PDF 1.6)
Should the Standard be set to None instead of a PDX?
Which version of InDesign are you using?
Sorry, I forgot to answer that earlier. It is version 6 on a Mac.
