The world’s default electronic paper technology, PDF files are opened hundreds of millions of times daily across the globe. PDF is in constant, heavy use for communications between publishers and printers, between individuals and organisations and throughout all levels of government.
Many persons with disabilities – especially those with visual or mobility impairments – require assistive technology (AT) to use electronic content, including PDF files.
PDF files must be “tagged” to be accessible. Historically, support for tagged PDF has been a relatively low priority for PDF software and assistive technology vendors.
PDF/UA (ISO 14289), a new ISO Standard, will change this paradigm. While AT users will benefit the most from PDF files that conform to PDF/UA, all users will benefit from standards-based support for accessibility-enabled PDF content in search, navigation and re-use implementations.
