Color contrast
When this check fails, it's possible that the document contains content that isn't accessible to people who are color-
blind.
To fix this issue, make sure that the document's content adheres to the guidelines outlined in WCAG section 1.4.3. Or,
include a recommendation that the PDF viewer use high-contrast colors:
1 Choose File > Preferences (Windows) or Acrobat > Preferences (Mac OS).
2 Click Accessibility.
3 Select Replace Document Colors, and then select Use High-Contrast Colors. Choose the color combination that you
want from the pop-up menu, and then click OK.
Page content
Tagged content
This check reports whether all content in the document is tagged. Make sure that all content in the document is either
included in the Tags tree, or marked as an artifact.
Do one of the following to fix this rule check:
• Open the Content panel and right-click (Windows) or Ctrl-click (Mac OS) the content that you want to mark as
an artifact. Then, select Create Artifact from the context menu. (To display the Content tab, choose View >
Show/Hide > Navigation Panes > Content.)
• Tag the content by choosing Tools > Accessibility > Touch Up Reading Order. Select the content, and then apply tags
as necessary.
• Assign tags using the Tags panel. Right-click (Windows) or Ctrl-click (Mac OS) the element in the Tags tree, and
choose Create Tag From Selection. Items such as comments, links, and annotations don't always appear in the Tags
tree. To find these items, choose Find from the Options menu. (To display the Tags panel, choose View > Show/Hide
> Navigation Panes > Tags.)

Sequence (Level A), 2.4.4 Link Purpose (In Context) (Level A), 3.1.2 Language of Parts (Level AA), 4.1.2 Name, role, value
Tagged annotations
This rule checks whether all annotations are tagged. Make sure that annotations such as comments and editorial marks
(such as insert and highlight) are either included in the Tags tree or marked as artifacts.
• Open the Content panel, and right-click (Windows) or Ctrl-click (Mac OS) the content that you want to mark
as an artifact. Then, select Create Artifact from the context menu. (To display the Content panel, choose View >
Show/Hide > Navigation Panes > Content.)
