Most of us know the “easy” PDF errors to fix – such as not setting the language or not adding alt text to images. But, what about those harder errors about annotations not being tagged, tables failing regularity, and “other elements” not having alternate text? Join me to learn how to clear these pesky errors and pick up some lesser-known tips!


You finish your award-winning PDF and run the accessibility check to find errors for character encoding, tagged annotations, table regularity, and other elements alternate text. What does this mean?! You tagged the content, including tables, and added alternate text to the images! These pesky errors can stump us, and the answers to these questions can be elusive even to the best “Googler”. From personal experience, resolving these errors was often trial and error. Now, I want to share what I have learned with you!

Join your peers in a session to demystify PDF accessibility! You’ll learn what the more difficult errors mean and how to fix them. You’ll also hear tips for using some of the lesser known options of the Tags and Content panels, manually tagging and marking content as artifacts, and hiding long descriptions for complex images. The end goal is to have you feeling more confident when working in Acrobat and to tackle any PDF errors thrown your way.

  2. Learn how to resolve the unclear PDF accessibility errors.
