PDF Accessibility involves several key steps to make documents inclusive for all users. These steps include tagging various elements within the document structure, such as headings, links, lists, tables, artifacts, figures, and form fields. Images require alternative text descriptions, and appropriate metadata should be set, including title, author, keywords, subject, and language. The reading order is crucial, established through tags and the reading order panel, and color contrast is tested for enhanced readability. The accessibility check is performed by clicking the left side of the PDF bar, right-clicking, selecting tags, and checking off "Highlight content." Additional actions involve setting document properties, conducting an accessibility check, and fixing errors. Manual checks with screen readers like NVDA and JAWS are recommended. The process also covers handling untagged PDF conversions, addressing OCR/scanned PDFs, and using tools like the axe Monitor for accessibility scans. The importance of defining tab order, creating and managing tags, and associating content with tags is emphasized throughout the document creation and accessibility enhancement process. Ultimately, this comprehensive approach ensures that PDF documents are visually clear and accessible to individuals using assistive technologies.
