I have written about the importance of adding a PDF/UA identifier to your PDF files to help with accessibility.
The PDF/UA flag in the document informs screen readers and AT software that the PDF’s structure elements are logically ordered and semantically correct. This enables the AT apps on different devices (desktop, mobile, tablets) to process correctly-tagged PDF content consistently for a multitude of users.
Let’s talk about why you should embed missing fonts
Embedding missing fonts ensures reliable presentation of the PDF document’s text because the AT viewer is not forced to substitute fonts that may not match the usage specified in the document.
Fonts that are embedded can also help speed up the editing process. Let’s say you discover a typo and need to fix it via Adobe Acrobat Pro DC. You should be able to fix the text in the document using the original font.
How to embed missing fonts
1. Open the PDF document in Adobe Acrobat Pro DC.
2. Go to Print Production > Preflight.
3. Make sure the Adobe Acrobat Pro DC 2015 Profiles is selected.
4. Select PDF fixups.
5. Select Embed missing fonts.
6. Press the Analyze & Fix button.
7. Save and replace the file.
8. Test in PAC 3.
