When creating electronic documents, you should strive to make the documents accessible to and inclusive of the widest-possible audience. The basic guidelines included in this section help provide a base level of accessibility when creating most types of electronic documents, including Microsoft Office, PDF, and other document formats.
Accessible documents are:
Each of these guidelines is crucial to create a document with a base level of accessibility:
These core guidelines for accessibility should be applied to all documents, regardless of the authoring tool or software. However, individual applications of these guidelines to each document may vary based on the authoring tool used.
Ideally, start with an accessible source document (e.g., in Microsoft Word) and export it to an accessible PDF. This preserves the document's accessibility features if it is edited in the future.
If the original document is not available, accessibility features can be added to the PDF using Adobe Acrobat Pro DC.
To review PDF accessibility, complete these steps by using Adobe Acrobat Pro DC:
Step 1Does document have text?
Try selecting document text using a mouse, or select all text using Edit > "Select All" from the Acrobat menu. If all text cannot be selected, then part or all of the document contains an image file and is not accessible. Convert to text using View > Tools > "Recognize Text."
Step 2Is document tagged?
Go to File Properties (Ctrl+D in Windows, Command+D in Mac). In the bottom left corner of the Document Properties dialog, see the "Tagged PDF" field. If status is "No" the document will need to be tagged. Tags provide the structure on which accessibility is built. Add tags by selecting View > Tools > Accessibility > "Add Tags to Document."
Step 3Check for other errors
Run the accessibility checker using Acrobat Pro. Select Tools > Accessibility > "Full Check" then read the report and follow the prompts. Please conduct this step last because some documents generate dozens of errors that can easily be addressed with the first two steps.
To manually inspect the tag tree in Adobe Acrobat Pro, select View > Show/Hide > Navigation Panes > Tags. This will display the tags in descending order. Visually inspect the tags to make sure the heading level structure is correct and elements are tagged accurately. More details >
