Checking the accessibility of Adobe PDF documents
You can check your Adobe PDF documents for accessibility before providing them to your
users. Acrobat provides you with an Accessibility Check command that lets you check
each document to see whether or not it has the information necessary to make it acces-
sible, including alternative text for figures, specified languages for text, reliable character
encodings, and a complete logical structure tree referencing all of its contents.
To check the accessibility of an Adobe PDF document:
1
Choose Tools > Accessibility Check.
2
Under Options, select Create Logfile to have Acrobat create a log file containing the
results of the accessibility check, and click Choose to select a location for the file.
3
Select Create Comments in Document to insert comments identifying individual
problems resulting from the accessibility check into your document.
4
Under Pages, specify the pages that you want included in the accessibility check. Select
Selected Pages to have the accessibility check performed on the page or pages displayed
in the document window.
5
Under Check For, select the accessibility requirements that you want to be checked.
Select Reliable Character Encodings to make sure that all characters include Unicode
values. An example of a character not including a Unicode value is a special font character
drawn in the document without any further information about what character it repre-
sents.
