PDF export options?
What is the content of the pages?
Is some transparency here?
How are the masters, same master on left and right side?
We exported the PDF as a X3 using Fogra 39L as the pre-set color space in InDesign. The PDF was exported as single pages.
The content of the pages is an image, spread over both sides (each double page).
There are no transparencies involved.
The output intent when exporting the PDF is ISOcV2 300. Once we changed the InDesign color settings to ISOcV2 300 the result was perfect.
Is there any explanation for this problem? Is there a way we can upload some screen shots to show you the results?
There's almost never a good reason to make CMYK to CMYK conversions, which is what you are doing when you export a document or image assigned with ISOcV2 300 to Fogra 39L.
A press can't have two profiles, so settle on the correct profile and assign it to the document via Edit>Assign Profiles... (not Color Settings Working CMYK) and then export to the same Document CMYK profile. Also use PDF/X-4, which will include the Output Intent and by default give you the correct preview in AcrobatPro
Use RGB images with a color profile and convert them not before PDF-Export, leave them as RGB up to the end. InDesign has the same result in converting files with the same settings as Photoshop has.
Thanks for your answer. We know that this is not the correct way. Unfortunately there was the wrong profile activated on this computer. What i want to know is, why pages 1 and 3 are correct and pages 2 and 4 are incorrect? If there was a problem with the profiles, every page should have been incorrect. Not only two of four pages.

Without seeing the ID file it's hard to know, but you clearly have conflicting CMYK profiles and CMYK objects on the page. It's possible to have CMYK images with different profiles embedded. So if ISOcV2 300 is the correct press profile there's no reason to have Fogra assigned to either the document or the images.
The Color Settings' CMYK Working Space is only used when the document has no profile assigned. So first assign ISOcV2 300 to the document via Edit>Assign Profiles.... Then make sure the placed images also have Document CMYK assigned—you can see the image assignments in the links Info panel. If the profile is not Document CMYK you can change it by selecting the image and choosing Object>Image Color Settings.
