Unfortunately, this only works if the PDF file is placed as a background in the MacOS version of Word and the subsequent use of the Word document is used in Word only under MacOS.
Except for MacOS use of Microsoft Office products, which for better or worse is a miniscule fraction of overall Office use, PDF is not natively supported.
A PDF placed as a background in MacOS version of Word is placed both as PDF and a low resolution (i.e., fuzzy-wuzzy) RGB raster image flavor of Microsoft's EMF format. When opened in Windows, all that is used is that EMF copy of the background with the obvious unacceptable results.
I do have an alternative that has proven to work very effectively, though.
- Export PDF/X-4 from InDesign.
- Open the resultant PDF file in Acrobat Pro DC.
- Use the fixup to convert all text to outlines (yes, this can terribly small point size type, but it is better than fuzzy-wuzzy low resolution raster).
- Save the PDF file.
- Create a new non-color managed CMYK Adobe Illustrator document and place (not open) the PDF file into the Illustrator document. Adjust content location and artboard size as appropriate.
- From Illustrator use File=>Export=>Export As and use the EMF file format.
- Close Illustrator.
- Open up the desired Word document and import the EMF file you created from Illustrator, placing as desired for a background without the “washout” option.
You made need to fool around with the original document size and possibly some fake white lines given that Word seems to do its own thing in terms of its percentage for placement.
Alternatively, you can simply insert the .EMF file into a Word document as a normal image, again adjusting to suit.
I have found that this works fairly well once you get the hang of it (and how Word scales EMF despite what you may ask for).
Note that this method does not work particularly well for complex graphics and/or graphics with small type for which outlining plays havoc. (Although EMF does support text, it doesn't support font embedding and a letterhead missing fonts, oy!).
