How do I ensure a PDF is accessible for screen readers or visually impaired users when reading comics?

Ensuring accessibility involves adding alternative text (alt text) to images, which describes the content of each panel for screen readers. Using a properly tagged PDF structure helps screen readers navigate the document logically. Descriptive captions for speech bubbles and sound effects are also beneficial. However, comic book PDFs often lack these features, making them difficult for visually impaired users to access. Look for publishers offering accessible digital versions or consider using tools to manually add alt text.
