Most people would agree that the best strategy for PDF accessibility is to integrate accessibility best practices prior to the conversion process, when the document is first being created. But in the real world, where legacy and automatically generated PDF documents abound, we don't always have the luxury of going back to the source document to fix accessibility issues. Sometimes, all we have to work with is the PDF document itself. So when the accessibility of that PDF document is so bad, and crying out loud that it sucks just isn't enough, then what do you do? Being able to rely on a backup plan to evaluate PDF accessibility and come up with a list of issues might be exactly what you need to figure out the full extent of the damage… When PDF Accessibility isn't exactly at the top of your LinkedIn Skills and Expertise list and you don't have access to someone who does, you need to roll up your sleeves and get creative. In this presentation we will see how much ground can be covered by combining the powers of the WCAG 2.0 guidelines and a customized checklist to determine the level of accessibility of your PDF documents.
