Make sure that your files (parent documents) are accessible before
you convert them into PDF:
How do you do this?
- Start with real text (not a scanned image of text, which is only a picture with no text)
- Use structural tags and navigation aids in the parent document
such as headings (not just large bold fonts), lists, links and
a table of contents
- Provide a text equivalent for every non-text element W3C
Techniques for text equivalents, and update the text equivalent
whenever the non-text object changes (WCAG Checkpoint 1.1 - Priority 1)
- Use clear language and a logical reading order (W3C
Techniques for clear pages WCAG Checkpoint 14 - Priority 1)
Creating Tagged PDF
- Create Tagged PDF by using Adobe
Acrobat version 5 and above, which has better accessibility
features than earlier versions. Tagged PDF is the most accessible
format
for
the latest screen
readers. Tagged PDF allows PDF files to contain logical
document structure and can be reflowed to fit small-screen
devices and
are therefore more accessible to the visually impaired
Why?
Scanned images of text cannot be read by a screen
reader becuase they contain no text and will not be accessible to a visually impaired user.
Your PDF file will only be as accessible as the file you created
it from.
