The Accessibility Checker will evaluate a PDF document to identify potential accessibility
errors in the file. However, the Accessibility Checker should not be used to evaluate the
PDF document for the logical reading order or to identify if alternate descriptions are correct.
Rather, the Accessibility Checker simply evaluates the technical accessibility of the PDF
document and whether or not the correct tags have been included in the document.
Additionally, there are elements the Accessibility Checker will mark as potential
accessibility errors that may not cause a problem for screen-reader technology or other
assistive computer technologies. It is necessary to review the original document with the
appropriate assistive computer technology as well as check the tagged document structure for
Paper Capture Plug-In
The Paper Capture tool provides Optical Character Recognition (OCR) for Adobe Acrobat
7.0. The Paper Capture Plug-In performs OCR on PDF document Image-Only files to extract
text content that is searchable. The Paper Capture Plug-In contains the same technology that
is used for the Adobe Paper Capture On-Line service, but will only support PDF documents
up to 50 pages in length. PDF documents longer than 50 pages require the Adobe Paper
Capture 3.0 software application. OCR support is provided for English, French, German,
Brazilian Portuguese, Castilian Spanish, Danish, Dutch, Finnish, Italian, Norwegian,
Nynorsk, Portuguese, Spanish, Swedish, Swiss, and German languages on both versions of
the Paper Capture software.
In general, the Paper Capture Plug-In provides a service to those individuals unable to access
the on-line version of the Paper Capture service. Both applications will perform OCR on a
PDF document less than 50 pages and return a document that provides content searchable
text. For additional functionality, including batch processing and zone processing, it is
recommended to use the Adobe Paper Capture 3.0 OCR software application.
Tables provide the ability to visually present related pieces of information in a quick and
easy format. Similar to data tables on the Web, assistive computer technology is not able to
recognize tables and render the content information in a recognizable manner to the user.
Rather, the user generally must navigate through the table hearing information, yet not
understanding the relationship between different pieces of content as displayed on the screen.
To create a table for a PDF document, it is necessary to use the Table formatting option in
the appropriate word processing program. Do not use "spaces" or "tabs" to visually
format a table as this will create the incorrect content in the root tagged PDF
Suggestions for a tagged PDF table:
1. The <Table> element should be the first markup "tag" before any content in the
table is described.
