Ensuring Accessibility: Managing Digitally Signed PDFs
As digital documentation becomes increasingly prevalent, ensuring that these documents remain accessible is essential, particularly when it comes to digitally signed PDFs. This blog post, part of our "Path to Compliance: Expert Solutions for Real-World Challenges" series, delves into the best practices for managing digitally signed PDFs to maintain compliance with 508 standards.
Preparing PDFs for Digital Signatures
Before we even consider applying a digital signature, it is crucial to ensure the document is fully accessible. Robert Scarbrough, a senior 508 Specialist, stresses the importance of finalizing all changes and accessibility remediation before signing. He advises, "This is a perfectly fine and normal way to handle digitally signed PDFs, but always finalize any changes or ADA/508 remediation before the signature." This step is critical because once a PDF is digitally signed, it becomes locked, preventing any further modifications.
Steps to Ensure Accessibility
Conduct an Accessibility Audit: Before signing, perform a thorough check of the document to identify and correct any accessibility issues. Use tools like Adobe Acrobat's accessibility checker to identify areas that need enhancement.
Incorporate Proper Tags and Headings: Ensure that your PDF includes the necessary tags and follows a logical heading structure. This helps screen readers to navigate the document efficiently.
Use Alt Text for Images: If your document contains images, ensure they have appropriate alternative text (alt text) descriptions. Alt text is crucial for users with visual impairments who rely on screen readers to interpret images.
Review Interactive Elements: If your PDF includes forms or other interactive elements, ensure they are correctly labeled and navigable using a keyboard, which is essential for users who cannot use a mouse.
Common Pitfalls to Avoid
One common mistake is assuming that a digitally signed PDF is still editable for accessibility adjustments. As Robert Scarbrough points out, the document becomes locked for security reasons after signing. Therefore, any attempt to modify the document post-signature could invalidate the signature and compromise both its integrity and accessibility.
Another pitfall is neglecting to review the document's reading order. Erratic reading orders can confuse screen readers, leading to a disjointed experience for users. Always check and correct the reading order before signing.
Advancing Accessibility in Digital Documents
Managing digitally signed PDFs is a nuanced process that requires attention to detail and a proactive approach to accessibility. By following these steps and avoiding common pitfalls, you can ensure that your documents remain compliant and accessible to all users.
