Eight Essentials for Creating Accessible PDF Documents
There are eight essential checkpoints to creating an accessible PDF document.
1. Bookmark your documents. Creating bookmarks in your document makes it easy to access the
chapters/sections of your document and for a reader to understand the overall scope of the
document and the way the information is organized. Bookmarked titles should be marked with
the appropriate H tag.
2. Create Articles. Documents like newsletters have articles in them that skip from page to page.
These kinds of documents are especially difficult for individuals using screen readers or
alternative input devices. Defining articles in your PDF document allows someone to follow the
article through the document without having to manually skip from page to page.
3. Reading Order. Sometime the content in PDF documents is read out of order by screen readers.
This is especially true of documents containing columns. Fixing the reading order of the
document will ensure that the information is presented to the reader in the correct order.
4. Semantic Tags. Content must be properly tagged so that a screen reader can know what kind of
information the content represents. This includes headers, body text, lists, images, backgrounds,
and tables.
5. Alternative Text for images. Where the content is an image that conveys information to the
reader, an alt tag should be used to provide the information to the screen reader user.
6. Links. If your document contains links, for example to a website (HTTP link) or to a location
within the document (Anchor link), the links must work. This includes links in the table of
contents for a document and any foot or end notes you have used.
7. Color. Color cannot be the only way information is conveyed to a reader. For example, if you
have a chart in your document, the legend cannot simply have “red” as the color identifying a
column. There must be a second visual clue for the reader for example using a “checkerboard”
pattern on the column.
8. Contrast. If you use background colors or images, there should be ample contrast between the
background and foreground (text). Overall does the font and spacing enhance the readability of
the content?
