Accessibility Checker Results Key & Limitations-2

Although the Accessibility Checker provides a thorough overview of document accessibility, there are still some elements that require human eyes for verification.  It is important to manually check if:

• the heading levels are in a logical order.
• the document has a logical reading order. 
• there is enough color contrast between the text color and background color. 
• the intended table rows or columns are designated headers .
• alternative text is described in a meaningful way.
• the links are descriptive. 

The Accessibility Checker is intended to provide a basic assessment of the PDF document and is not reflective of a full and complete accessibility analysis. It is an automated tool and, as such, can only test a handful of the accessibility standards.
