Evaluating and Repairing PDFs

This workshop will focus on incorporating accessibility features into existing PDF documents. It is always better to build as much accessibility into the source document (.docx, .pptx or .indd) as possible before converting to PDF. In situations where you don’t have the source document, you can build accessibility into an existing PDF using Adobe Acrobat DC. Techniques include:

Converting an image/scanned PDF to real text
Tagging
Adding alt text to images
Creating headings and bookmarks
Adding table headers
Checking and correcting read order

NOTE: Remediating PDFs for accessibility can be an extremely time consuming task. Consider whether the content you are trying to make accessible must really be in the form of a PDF before you begin. For example, if you are trying to remediate a document that was originally created in InDesign and intended for print, perhaps creating a web page that contains the same information along with a link to the printable PDF might be a better option.

Segment Title	Description	Duration
Introduction	Introduction to accessibility guidelines and the importance of creating accessible documents. Note: this introductory material is from the 'Creating Accessible Documents in Microsoft Word' course, but the content is relevant here as well.	4mn38sec
Screen Reader Demonstration: Reading a PDF with Jaws	A demonstration of using the JAWS screen reader to read and navigate a PDF document.	3mn7sec
Acrobat DC: Setting Up Your Workspace for Accessibility Remediation	Adobe Acrobat has several accessibility remediation tools that should be added to your tools panel for easy access. These include: The Accessibility Tool, the Action Wizard, the Enhance Scans Tool, and the Prepare Forms Tool. You should also add a few icons to your left navigation panel for easy access to the Bookmarks, Content, Reading Order, and the Tags panel.	1mn20sec
The Document Navigation Pane	Use the document navigation pane to move between document bookmarks, content elements, the reading order pane, and the tags panel.	2mn11sec
Using the Accessibility Checker	Use the built-in Accessibility Checker to identify common accessibility errors in your document.	0mn43sec
The Make Accessible Wizard	If your accessibility check results in a large number of errors, you may be dealing with an untagged PDF. Use the Make Accessible Wizard in the Action Wizard panel to recognize text in a scanned document, add tags to the document, and add alternative text to figures.	1mn15sec
Fixing Alternative Text Errors	Locate and fix missing alternative text on figures, or flag images as purely decorative.	2mn17sec
Fixing Heading Errors	Identify skipped or missing headings in your document, or add headings to a document that doesn't have any.	3mn17sec
Adding a Table Header Row	When it comes to data tables, the most common accessibility error is the lack of a defined header row. Without a header row a screen reader cannot correctly interpret the cells in the table.	1mn42sec
Checking Reading Order	A screen reader like Jaws will read the document content in the order they are presented in the tag tree, which may not match the visible order on the page. Adjust the location of elements in the tag tree as needed to maintain a logical reading order for users of assistive technology.	1mn2sec
