In this session, learn about the challenges, both foreseeable and surprising, that one encounters when performing large scale PDF/UA remediation. Also learn some techniques to resolve those challenges.


Enterprise PDF/UA remediation involves many challenges that one should expect, including issues with remediation at scale and issues with dynamic document contents and layout. Enterprise PDF/UA remediation also involves technical challenges that one may not expect, for example: weird encodings, missing spaces, and how PDF ActualText works – or doesn’t. You’ll learn about these expected and unexpected challenges and how software can help solve them.


  1. Enterprise remediation presents unique challenges.
  2. Dynamic documents can be subdivided into sections to address the accessibility of each section independently.
  3. Certain document features require specific solutions to achieve accessibility.
