Creating Section 508 CompliantPDF Documents I Module 1 – Introduction and HHS Document Requirements
HHS PDF Document Layout and Formatting Requirements The document should be properly tagged The document language should be specified The document should have a logical reading order Table of Contents (TOC) and Bookmarks must be functioning correctly
HHS PDF Document Layout and Formatting Requirements All URL’s must contain the correct hyperlink and display the fully qualified URL All URLs must be linked to an active Web Destination All Acrobat Comment and Markup items must be removed from the document All Acrobat Accessibility Tags must be correctly applied to the document
HHS PDF Document Layout and Formatting Requirements A Full Accessibility Report must be run on the document Documents that contain multi-column text, tables, or call-out boxes should be checked for correct reading order using assistive technology or the Acrobat Reader ‘Read Out Loud’ function Any document that is unable to be made accessible will need to have a separate accessible version available for disabled users to access This version must have all of the capabilities (e.g. bookmarks) of the PDF
HHS PDF Document Images Requirements All images, grouped images or non-text elements must have Alternative Text associated with them Documents comprised of scanned images of text are not 508 compliant Complex images must have descriptive text immediately after the image Multiple associated images must be grouped as one object (i.e. single flattened image) All multi-layered objects must be flattened into one image and use one alternative text (alt tag) for this image
HHS PDF Document Tables Requirements Documents containing data tables should have readily identifiable row and column headers Tables should be used to organize information into a tabular format Data tables should have a logical reading order from left to right and top to bottom
HHS PDF Document Tables Requirements Table cells should be logically associated with the Row/Column Header Tables should be named, have a table number (if applicable) and have a description below the table All cells within a data table, that are not part of the header row, must be designated as “data cells”
HHS PDF Document Best Practices A visual check should be done to the document to ensure that no hidden data from any application used to create the original document is present in the resulting PDF file The document file name must not contain spaces or special characters (!,;:?{}@/\=+parentheses?
HHS PDF Document Best Practices The document file name must be concise, generally be limited to 20-30 characters, to make the content of the file clear in the context in which it is presented Scanned signatures within documents are a considered a theft-of-identity risk and should not be used The document must utilize the recommended fonts i.e. Times New Roman, Verdana, Arial, Tahoma and Helvetica
Use Document Properties as Best Practices Properties Summary tab Shows document creator and ownership Gives author of the document Further contact information

Module 2 – Creating PDF Documents • You have completed Module 2 • You can convert a Word document into a PDF • Using Adobe Acrobat Professional • Using Microsoft Word
Creating Section 508 CompliantPDF Documents I Module 3: Structuring Documents
Structure Document structure gives a logical reading order A document that is well-structured and logically organized can easily be: Read and navigated by assistive technology Exported to other applications, with minimal adjustment to maintain accessibility Certain specifications need to be identified for text elements, non-text elements (images, tables, and diagrams), organizational aids and navigation aids
Adobe Acrobat: PDF Accessibility PDF tags create accessibility For a PDF document to be accessible it must contain the following: Actual text, scanned images are not accessible Tags that create the appropriate document structure Reading order specified for columns and tables Alternative text for images
Adobe Acrobat: PDF Accessibility Navigational aids as needed Fonts that allow characters to be extracted to text Security settings that do not interfere with assistive technology
Tagged PDF Tags are a text only representation of the PDF file that is presented to Assistive Technology (AT). They create the document’s structure and functionality PDF documents use tags to indicate the page elements that define the document’s content structure and how elements relate to one another Elements include: headers, paragraphs, tables, graphics and lists
Verify Status Using the Tag tab, will denote if the document is tagged or not If no tags appear, the document is untagged From the Content tab, review the document’s content If no text appears in the Content pane, the document is a legacy PDF or image Selecting the Order tab will reveal the reading order If the document is untagged or does not contain actual text, the reading order will not exist Document Status
Tagging Converted Documents • Converting documents to PDF may generate an untagged PDF • Untagged or poorly tagged PDFs are not accessible • Combining several PDFs or other files into a single document results in a poorly tagged PDF [covered in PDF II]
Tagging an Untagged PDF • Select Advanced > Accessibility > Add Tags to Document
From Office formatted document: From the Order tab, review the documents reading order Remove empty containers and adjust reading order Edit tags Test for accessibility From legacy PDF or paper document (covered in PDF II) Accessibility review of documents
