Step 7: Use the Accessibility Checker to Evaluate the PDF File
The accessibility checker tools (Quick Check and Full Check) can help to identify areas of
documents that may be in conflict with Adobe's interpretations of the accessibility
guidelines referenced in the application and its documentation. However, these tools
don’t check documents against all accessibility criteria, including those in such referenced
guidelines, and Adobe does not warrant that documents comply with any specific
guidelines or regulations.
Quick Check
Use Quick Check to check for document structure tags, searchable text, and appropriate security settings for
accessibility. This method is often the best way to check for accessibility before attempting to use a PDF.
Quick Check Results
• This document has logical structure but it is not a Tagged PDF. Some accessibility
information may be missing.” Quick Check has found an underlying document structure
in the document, so Acrobat will use the available document structure to control the
reading order, rather than analyzing the document itself. However, this untagged
document structure might be incomplete or unreliable, so assistive software and the
accessibility features in Acrobat (such as the Read Out Loud and the Save As Text features)
may not read the page properly. If the reading order of the page seems to be wrong, select
Override The Reading Order In Tagged Documents in the Reading panel of the
Preferences dialog box.
• This document is not structured, so the reading order may not be correct. Try different reading
orders using the Reading Preferences panel.” . Quick Check has found no underlying
document structure that Acrobat can use for reading order. Acrobat will analyze the
reading order of the document using the current analysis method set in the Reading Order
preference, but this PDF might not be read correctly by screen readers. If the reading order
seems wrong, select a different option for Reading Order in the Reading panel of the
Preferences dialog box.
• No accessibility problems were detected in this quick check. Choose the Full Check command to
check more thoroughly. Quick Check has found that the PDF contains searchable text, is
tagged, has an underlying document structure, and has no security settings that prohibit
access for screen readers. To check for other types of accessibility problems that may be
present in the PDF, use Full Check.
