Select Adobe PDF to choose from options for the Adobe PDF accessibility standard:

  • Alternative Descriptions Are Provided Checks for tagged figures that are missing alternate text.

  • Text Language Is Specified Checks for paragraphs that don’t have a language specified for them. Setting the language for an entire document in the Document Properties dialog box corrects all errors related to this option.

  • Reliable Character Encoding Is Provided Checks for fonts that are inaccessible to screen readers and other assistive software. Fonts must contain enough information for Acrobat to correctly extract all the characters to text. If one or more fonts don’t allow for the correct extraction of all the characters, the PDF is inaccessible.

  • All Content Is Contained In The Document Structure Checks for page elements that have been overlooked during tagging. Adding these elements to the tag tree (if necessary) ensures that a screen reader can present the content to a user.

  • All Form Fields Have Descriptions Checks for form fields that are missing descriptions.

  • Tab Order Is Consistent With The Structure Order Checks whether tags properly reflect the document structure.

  • List And Table Structure Is Correct Checks whether tags that have been generated for lists and tables meet the requirements of tagged PDF.
