TIP 59: Basic Document Tagging

Some program features used to enhance accessible use, such as articles and reflow, don't work properly or predictably unless a document is tagged, which means it has a logically defined structure. Tags are invisible and are a part of the document's information. They define relationships among elements in the document, including tables, lists, images, and text.

Planning Documents for PDF Accessibility

The key to successful tagging of a document as well as making it comfortable for a user working with a screen reader is to use your source programs' features efficiently. Plan ahead. Here are a few examples:

  • Configure the document pages correctly. Don't add blank lines to make a space.

  • Check the styles attached to inserted material such as images and charts.

  • Group tables and charts or convert them to an image before conversion to prevent creating individual tags for each line and word segment.
