Adobe® Acrobat® XI Pro Accessibility Guide: Best Practices for PDF Accessibility

Tagged PDF:

If this rule check fails, the document is not tagged to specify the correct reading

order for reflow and assistive technology. Documents without tags also do not provide

information describing the logical structure and relationship of elements to users of assistive

technology.

To fix this item automatically, select Tagged PDF on the Accessibility Checker panel, and then

choose Fix from the Options menu. Acrobat automatically adds tags to the PDF. °e tags that

were added still must be reviewed to ensure they are correct.

Note:

Refer to the related WCAG section: 1.3.1 Info and Relationships, 1.3.2 Meaningful

Sequence, 2.4.1 Bypass Blocks, 2.4.4 Link Purpose, 2.4.5 Multiple Ways, 2.4.6

Headings and labels, 3.1.2 Language of Parts, 4.1.2 Name, role, value

Logical reading order:

Verify this rule check manually. Make sure that the reading order

displayed in the Tags panel reflects the logical reading order of the document.

Primary language:

Se±ing the document language in a PDF enables some screen readers to

switch to the appropriate language. °is check determines whether the primary text language

for the PDF is specified. If the check fails, set the language.

To set the language automatically, select Primary Language in the Accessibility Checker tab, and

then choose Fix from the Options menu. Choose a language in the Set Reading Language dialog

box, and then click OK. °is does not set the language for specific parts of the document that

may be in different languages. To set specific portions of the document in different languages

refer to the Adobe Acrobat XI Pro Accessibility Repair Workflow guide.

Note:

See the related WCAG section: Language of Page (Level A)

Title:

Reports whether there is a document title. Document authors can choose to have the title

appear in the Acrobat or Adobe Reader application title bar rather than the document file name.

To fix the title automatically, select Title in the Accessibility Checker tab, and choose Properties

from the Options menu. Enter the document title in the Description dialog box (deselect Leave

As Is, if necessary).

Note:

See the related WCAG section: 2.4 Page Titled (Level A)

Bookmarks:

°is check fails when the document has 21 or more pages, but does not have

bookmarks that parallel the document structure.

To add bookmarks to the document, select Bookmarks on the Accessibility Checker panel, and

choose Fix from the Options menu. In the Structure Elements dialog box, select the element(s)

that you want to use as bookmarks, and click OK

(See “Figure 8. Fix missing bookmarks in

Acrobat” on page 15)

. You can also access the Structure Elements dialog box by clicking the

Options menu on the Bookmark tab.

Note:

Ways (Level AA)
