What are the common pitfalls or challenges of creating accessible PDFs and how do you overcome them?

As the summary says, this is the first stop in making documents accessible. The PDF-UA standard is very similar to WCAG for web, in that it follows a similar mandate of heading hierarchy, image descriptions, proper flow, etc. It is easy to have an accessible PDF if your source document (Word, InDesign, etc.) is properly structured. There is also a disadvantage to remediating the output PDF if the source is still inaccessible, because that means any change to the document will require re-remediation, which is costly and redundant.

When creating accessible PDFs, common pitfalls include issues with color contrast, improper heading structure, missing alt text for images, incorrect reading order, and using scanned documents that aren't machine-readable. To overcome these challenges, ensure you use appropriate color combinations, properly tag headings, provide descriptive alt text for images, structure the document logically, and convert scanned documents to text-searchable formats.

- Make sure the source documents accessibility regulation are met. - Fix out the missing heading structure and image alt texts to make it more semantic. - The source document must be fixed first, and converted to PDF last so that the accessibility is not compromised.

"An inaccessible source document leads to an inaccessible PDF." Always ensure proper structure and use accessibility checkers from the start to avoid manual fixes later.

Missing or incorrect PDF tags can make navigating and accessing information difficult. PDF editors like Adobe Acrobat Pro can help identify untagged content and assign proper tags like headings, figures, and tables. This creates a structured document for easier reading and navigation, especially for assistive technologies.

- Review and where necessary manually add or correct tags. - Make sure that each table is marked appropriately. - Check reading order and content structure for the screen reader users.

"Avoid missing or incorrect PDF tags!" - Tags define the structure for assistive tech. - Many PDFs lack proper tags, resulting in confusion. - Consider using the PDF editors to auto-generate or manually adjust tags, ensuring accurate navigation and accessibility.

It is important to provide alternative text that accurately describes non-text content like images in a PDF document. You can insert this text using PDF editor tools like Adobe Acrobat Pro.

Make your PDFs inclusive by ensuring images and graphics are accessible! Add alternative text ("alt text") to describe visuals for screen readers. Use PDF editors to insert alt text in the source or with built-in tools. This ensures everyone can access your content.

When creating accessible PDF documents, it's best to use simple designs with minimal interactive elements. If interactive elements are essential, align them with Universal Design principles such as DfA. Detailed alt texts and simplified navigation ensure assistive devices can easily detect them. PDF tools often have built-in accessible forms and elements, along with many design software checkers. Inclusive design principles are often overlooked due to the extra 'man hours' required or a lack of awareness and importance of such tools.

- Make the forms labels and interaction elements easy to understand. - Make sure that elements have programmatically their functionality addressed. - Test whether the form is accessible through keyboard navigation and if it works properly.

"Make your documents inclusive and user-friendly." - Proper labels, logical tab order, and keyboard-friendly elements help everyone interact seamlessly. - Use PDF editors to add names, roles, and states for assistive technologies.

- Try not to use just one color for presenting information. - Make sure text and background have enough color contrast. - Use the color contrast checkers to ensure the compliance with the accessibility guidelines.

As the title suggests, "Ensure accessible color and contrast in PDFs!" - Use minimum contrast ratios (4.5:1 for text, 3:1 for graphics) per WCAG. - Don’t rely solely on color to convey info. - Utilize contrast analyzer tools to verify and adjust colors, making your documents readable.

Inaccessible fonts make documents difficult to read and understand. You can fix this challenge with PDF editors by embedding the missing fonts or swapping them for fonts your computer recognizes.

"Here's how I ensure accessible fonts and text in PDFs!" - Make use of legible sizes, clear styles, proper spacing, and embed fonts to display correctly on all devices. - Clear, readable text makes the documents usable for everyone.

- Include real user insights to enhance accessibility! - Understanding diverse experiences ensures your PDFs are truly inclusive.

There are may free tools available to test the formatting of your PDF. If you are at all familiar with the structures of WCAG for websites, you will find understanding these tests relatively easy. If you have access to the source document, you can easily remediate the accessible features and re-export to PDF.
