      You are saying that the mentioned workflow is no more valid for AcrobatPro
      9 ? What's different ?




There must be some misunderstanding here: My workflow involved exporting the pdf from Indesign with the profile embedded. I'm trying to find where exactly in Acrobat 9 I can confirm that the profile is actually embedded. I didn't find anything in the document link you provided that gives this information - unless i'm missing something?

In Acrobat 9, I can go to the Advanced menu > print production > preflight - but I can't find anything in this complicated dialogue box that allows me to check for the existence of an embedded profile. I just thought that someone may be familiar with Acrobat 9 and may know where I can check this kind of thing.

      Yes, PDF/X-1a is ideal. Not a reason for confusion. It's absolutely correct
      to use the same profile for all conversions, but it's not necessary to
      embed it in each image.




You say it's not necessary to embed it in each image. I was reading back at your post #22 and you were saying:

      Also a good solution, after soft-proofing the RGB images by Photoshop:
      use RGB images, make a PDF and convert this globally into the destination
      space by Acrobat Professional.




So clearly from the above quote, if I was to use that workflow I shouldn't necessarily embed any CMYK profile in any of the images, in fact the images shouldn't be CMYK at all - they should be RGB according to your post #22. If I understand the theory correctly, if I was to use that workflow and have CMYK images, the numbers would all change when I converted to profile within Acrobat Pro, right?
