Complying with PDF
and Accessibility Standards
Traditionally, the preflight process tests files for compliance with certain
printers or standards. The concept of preflight has changed from that of a
testing tool to one of the most powerful features in Acrobat. Along with
evaluation, you can also employ fixups, which modify your document
for everything from flattening form fields to moving comments off the
printing area.
Acrobat 9 Pro takes the evaluation and fixup process further than ever
before, letting you specify a particular area or view to evaluate or repair, or
even create layers to separate your document’s objects. Just as you might
certify a document with a digital signature to indicate you are the author
or approve the content, Acrobat 9 includes a preflight audit trail, add-
ing a digital signature automatically to certify your document’s standards
compliance.
If you find opening dialogs and running preflight profiles repeti-
tious, make yourself a program to run features automatically from the
desktop.
Output standards also apply to accessibility features. Acrobat 9 offers a
range of features that allow users who are visually or motion impaired to
work with PDF documents. You’ll find testing options to establish whether
a document complies with different accessibility standards, and evalua-
tion reports that help you correct accessibility issues.
Tags are a key element in making accessible documents. Acrobat con-
tains a number of ways in which you can apply tags to a document, evalu-
ate the status of the document, and use the tags for manipulating the
document and its contents.
