One last try, pretty please: 1. Open InDesign and with no document open: "Color Settings", set US Web Coated SWOP. as CMYK working space. As Colour management policies, set CMYK: Preserve numbers (Ignore linked profiles). Check the three "Ask when..." options. 2. Open the conflictive document. If asked anything, choose preserve embedded profiles. 3. Open the separations in the Output panel and check that the black text is still black (CMYK: 0/0/0/100) 4. Edit -> Assign Profiles, CMYK assign CMYK working color space (should be US Web Coated SWOP. as CMYK). 5. Edit -> Convert to profiles, from CMYK source profile (whatever it is) to Destination space... CMYK profile Working CMYK (US Web Coated SWOP). 6. Save. 7. Export as PDF, choose PDF/X-4 (the exact taste 2008 or 2010 depends on the version of your InDesign and is not very relevant to this issue, IMHO). 8. In the PDF export dialogue, go to the Output zone and choose Color conversions; Convert to destination (Preserve numbers). 9. Export. 10. Go to Acrobat Pro (you already have it, haven't you?). Open the PDF. 11. In tools, go to Print production, go to preflights profiles and choose one of the PDF/X compliance that verifies (not "convert", "verify") PDF/X-4 level. Push "Analyze" button and check that it is PDF/X-4 compliant (the profile now is irrelevant, we just want to check that the PDF is really a PDF/X-4). 12. In Tools, print production (still in Acrobat), go to Output preview. The simulation profile offered should be US Web Coated SWOP. Check that the black text is CMYK 0/0/0/100. If, after this walkthrough, your text still seems to be in rich blak (could happen. I managed to do that myself)... please choose as Simulation profile US Web Coated SWOP. Any other CMYK simulation profile will perform a color conversion (even for preview) and they are usually passed through a Lab space that converts black ink into rich black. Printing or simulating with the proper profile should show 100% black properly as pure black ink. Otherwise... the smart and dirty solution to overcome this is what Stephen_A_Marsh recommends: use Acrobat to solve the issue for the moment. But then I guess that although something seems wrong with the installation of your computer or the settings of your Adobe Suite, the culprit will be some tiny and maddening detail in your workflow. Being there, done that Best regards
