Checking the accessibility of Adobe PDF documents
It's always a good idea to check your Adobe PDF documents for accessibility before
distributing them to users. The Quick Check feature quickly examines your Adobe PDF
document for structure and tags to see if it has the information necessary to make it
accessible. It also checks for protection settings that prohibit access and determines if the
document is a scanned image (and therefore inaccessible). It returns a brief statement of
any accessibility issues.
If you require a detailed report of accessibility problems and suggestions for fixing them,
run the Full Check feature. You can check a PDF document for specific accessibility
elements, such as image descriptions, or use the default settings to generate a
comprehensive report.
When you run the Full Check feature using the default settings, a report opens in the How
To window that lists errors and provides suggestions for repairing them. Because the Full
Check feature is unable to distinguish between essential and nonessential content types, it
may report issues that don't affect readability, so it's a good idea to review all issues to
determine which ones require correction. Full Check saves an HTML report with the same
name as the analyzed PDF document so that you can refer to it later.
Note: A full accessibility check can be time-consuming. You can stop the process by
pressing Esc and can choose a smaller page range in the Accessibility Full Check dialog
box.
To check the accessibility of a PDF document using Quick Check:
Choose Advanced > Accessibility > Quick Check.
Note: If the document is unstructured, a message may appear, suggesting that you change
the reading-order preference. (See
Setting Reading preferences .)
To check the accessibility of a PDF document using Full Check:
1. Choose Advanced > Accessibility > Full Check.
2. Select Create Accessibility Report, and then click Browse to save a copy to the location
you want.
3. Specify the pages that you want included in the accessibility check. To view the report as
comments in the PDF document, select Create Comments In Document.
4. Select the Checking Options that you want, and then click Start Checking.
A report opens in the How To window with a list of problems and links to specific areas
of the document.
Note: Errors must be corrected manually. (See Correcting tags .)
To reopen the Full Check accessibility report:
1. Choose Advanced > Accessibility > Open Accessibility Report.
2. Select the HTML file, and then click OK. The report appears in the How To window.
3. In the How To window, click any of the links to highlight the error in the associated PDF
document within the document pane.
Note: To reopen the accessibility report with the associated PDF document, both files
must be located in the same folder as when you ran the Full Check command.
