Professional.

On the tagged PDF document, perform an accessibility Full Check to isolate problems with
PDF accessibility.
To help improve the accessibility of tagged PDF documents, you can use the Acrobat user
interface or the Acrobat SDK to:
Create document navigation by adding bookmarks to the document (see
●
Managing Bookmarks" on page
Add alt text to images
●
Create hyperlinks, which enhances accessibility because it is easier to activate a
●
hyperlink than to search for a specific reference point in the same or another document
(see
Add watermarks that optimize the accessibility of the PDF document (see
●
Pages of a PDF File" on page
Manipulate the tag structure tree using the

Acrobat and PDF Library API Overview)

Making Forms Accessible

The follwoing accessibility tips can make your forms more easily usable by all users.

Field Descriptions

Every field that is not hidden should contain a user-friendly name. This name is spoken
when a user acquires the focus to that field and should give an indication of the field's
purpose. For example, if a field is named
First Name. The name should not depend on the surrounding context. For instance, if a form
asks for the first name of both a person and their spouse, the field in the spouse section
might be named Spouse's First Name.
This description is also displayed as a tooltip when the user positions the mouse over the
field.
