Cannot extract the embedded font error

In examining yet another PDF file sent my way with these symptoms, we found that the underlying problem was in the production of the PDF file. The creator of the PDF file (it wasn't Adobe software or any Adobe PDF libraries) improperly embedded the fonts in terms of both how they were identified (claiming they were TrueType although they were Type 1) and with messed-up encoding tables.

The fix in this particular case was to open the PDF file in Acrobat Pro DC, invoke Preflight, and run the Fix potential font problems profile in the Acrobat Pro DC 2015 Profiles group. This appears to have resolved the problem, at least for this file.

I have been seeing this issue in our print output workflow for awhile, and I have only been able to fix this 2 ways. 

1.  As mentioned above, with Acrobat you can print the file to PDF by chosing 'Adobe PDF' as your printer.

2.  Purchase a third party tool called PDF Toolbox, use the PTB_Redistill function on the PDF (this can be automated)

Does anyone know what the fond CIDFont+F1 would be?  The only fonts on my PDF that I can see are Arial and Arial Narrow.

I had the same problem but it stopped as soon as I exported the PDF as "spreads" and not "pages". (Using InDesign)

I was having the issue exporting a PDF from Adobe Indesign. I had to re-login to the Adobe Acrobat software using my Adobe user information and that fixed the issue.

We encountered this on a network with around 50 users. Most could open the file, but a couple could not. The solution we found was to use Microsoft's Print To PDF option to regenerate the PDF file. That regenerated file was able to be opened by the users that experienced the problem with the original.

Note that we encountered errors on the file which was created by MS Publisher in both Chrome as the reader and Adober Reader on the machines with the problem and despite being the same version of Chrome and Reader on the other machines, only a few had the issue.

Hey all!

Here we are in mid-2015, and still this problem persists.

I have run into this issue also, but no work-arounds seem to be fixing the problem, and I just can't seem to figure out what could be corrupt.

It started with third party PDFs, then became almost all PDFs that began their lives as either InDesign (CC) files or Keynote (6.5.3) files. This began when I had Acrobat X, and is continuing now that I have Acrobat XI. In fact, a lot of people in my office have run into the issue, some files open just fine for some people, then don't open for others and there is no real pattern to the madness.

Our office is made up primarily of mac computers running Mavericks and Yosemite. We all have the most up to date Creative Cloud, Acrobat and Keynote, we also all share fonts on a universal type client. Whenever we export to PDF and open those PDFs with Acrobat Pro XI, those PDFs show up with blank spaces where some of the text should be, and an error is shown saying that the embedded font could not be extracted. Even when I make a fresh Keynote or InDesign file from scratch the resulting PDF returns the same error. Obviously, the "use local fonts" trick doesn't work here. (I also tried extensive troubleshooting, using other computers in the office, working with people in offices we have in other countries and cities, installing fonts locally and disconnecting from the type client, etc.)

Could you please go into detail on what you think could be corrupt across all of these files? Do you think it's a Keynote issue? An InDesign issue? An issue with the fonts themselves? Perhaps something crazy going on with our entire computer network? I've tried with numerous TTF and OTF fonts with hit-or-miss results across the board. Our IT department is also baffled, having flushed the UTC cache, as well as local computer cache multiple times - the only thing that we all unanimously agree upon is that it seems to be an Acrobat problem.

I would absolutely love some help from anyone on this matter! I seem to be able to find a lot of questions in forums, but no helpful answers...

Thanks!
