What is Accessibility?

  • Accessibility involves two key issues:

    • How users with disabilities access electronic information

    • How content designers, developers, and authors produce content that functions with assistive devices used by individuals with disabilities.

    • Accessibility is not a feature, it’s about procedures, processes, and techniques

      • Acrobat Forms (Forms Panel in Acrobat X Professional)

    • Searchable PDF

  • You Intend to Create a PDF File

    • Applications that Create Tagged PDF

      • PDF Maker (for Microsoft Office)

      • Other Applications

    • PDF Form

      • LiveCycle Designer (Application Distributed with Acrobat X Professional)


Scenarios for Accessible PDF

  • You want to evaluate and repair a PDF File

    • Scanned PDF

    • PDF Forms

      • Acrobat Forms (Forms Toolbar in Acrobat 8 Professional)

    • Searchable PDF

  • You Intend to Create a PDF File from another Application

    • Adobe FrameMaker

    • Adobe InDesign

    • Adobe LiveCycle Designer

    • Microsoft Word

    • OpenOffice.org

  • You want to consolidate documents into a PDF portfolio


The PDF Accessibility Workflow....

  • Ask Yourself a Series of Questions in this Order

    • Is the PDF a Scanned Image?

    • Is the PDF Intended to be a Form?

    • Is the PDF Tagged?

    • Are the Items Properly Tagged?

      • Verifying read order

      • Verify proper tagging (i.e., figures, tables, etc.)

      • Add alternate text descriptions to graphics

      • Add short descriptions to form fields

    • Have I Missed Something?

      • Run the Accessibility Checker

        • Make recommended and appropriate repairs until no problems found

  • You Can Consolidate These Steps Using the Action Wizard


1. Open the PDF File

  • From Acrobat

    • From the Menu

      • File > Open

    • Keyboard Shortcut

      • Ctrl + O

    • Accelerator Keys

      • Alt + F + O

  • From Outside of Acrobat

    • Tab to file and select (begin typing file name)

    • Click on a PDF file

    • Right Mouse Click (“Open With...”)


2. Analyze the Content – Give Yourself an Idea of What Lies Ahead

  • Determine the Complexity of the Document / Page

    • Short document (a few pages) or a long document (many pages)

    • Single Column / Multi Column?

    • Are there graphics present?

    • Tables?

    • Does it appear to have multiple headings?

    • Does it appear to have form fields

    • Is the layout easy or difficult to follow (side headings for example)?


3. Determine if the PDF File is a Scanned Image

  • Verify the presence of searchable text

    • Zoom In, Look for “Jaggies”

    • Search for Text on the Page (Ctrl-F)

    • Run “Read Out Loud” on the Page

    • Run a Screen Reader


If it is a Scanned Image... Perform OCR

  • Optical Character Recognition

  • Tools Pane > Recognize Text

  • Menu: View > Tools > Recognize TextAlt + V + T


4. Locate URLs and Activate Links

  • Use Acrobat’s Create Links from URLs Command

  • Tools Panel > Document Processing > Create Links From URLs

  • Menu: View > Tools > Document Processing (Alt + V + T + U)


5. Determine if the PDF File is Meant to be a Form

  • Visual Inspection

    • Does the Document Appear to be Soliciting Information – Name, Address, Social Security Number?

    • Read Out Loud / Screen Reader Also Offer Clues for the Visually Impaired


If the PDF File is Intended to be an Interactive Form...Add Form Fields

  • Automatically detect Form Fields

  • Add form fields using the Acrobat Forms Tools


6. Determine if the PDF File is a “Searchable PDF”

  • If you have performed the previous steps on the other PDF file types, your PDF will be a “searchable” PDF at this point

    • You Have Ruled Out or Corrected for the Scanned Document

    • You Have Ruled Out or Corrected for the Form

    • Now It Behaves as if it Came from a Word Processing or Desktop Publishing Application


7. Determine if the PDF File is Tagged

  • Verify the presence of tags

  • Add tags if necessary


If the PDF File is Not Tagged...then add Tags to the File

  • Add Tags to Document

  • Tools Panel > Accessibility


8. Determine if the Items are Properly Tagged

  • Use the Touchup Reading Order Tool

  • Tools Panel > Accessibility > TouchUp Reading Order


9. Make Sure You Have Not Missed Anything

  • Run the Accessibility Full Check

  • Tools Pane: Accessibility > Full Check


Create an Action for Your Accessibility Workflows

  • No Need to Commit All These Steps to Memory – Create an Action

  • Two are Provided

    • Create Accessible PDFs

    • Make an Accessible Form

  • Tailored Actions for Specific Documents


Microsoft Word to Accessible PDF – Use the Adobe PDFMaker

  • Add Alternative Text to Graphics in the Word File

  • Do NOT Use Spaces, Tabs to create tables, use the Table Editor

  • Do NOT Use Character formatting for Headings, Use Styles

  • Set Your Preferences from the Microsoft Word Menu: Make sure “Enable Accessibility and Reflow with Tagged PDF” option is selected

  • Convert with Adobe PDFMaker

  • Check the Results in Adobe Acrobat X

  • Follow the Suggestions for Repair, Repeat Until No Errors Detected


Loose Ends (Some Common Errors That Crop Up)

  • Check the Language Attribute in Acrobat

  • Use Tags Panel to Provide Table Headers <TH> in First Table Row

  • Fix Tab Order Does Not Correspond with Read Order Error


A Caution Regarding Automated Checking

  • There is NO Accessibility Button – Accessible Content Creation is a Process NOT a Feature

  • Achieving Accessibility Requires Human Testing in addition to Automated Checking

  • Checking Can Only Detect for the Presence or Lack of Required Items

  • Cannot Check if an Item is Correct or Appropriate

  • Accessibility is a New Item for the Production Workflow – Like Authoring, Layout, Proofreading, etc.

  • Note Also, Publishers Will Need to Employ a Variety of Techniques and Methods


Adobe Acrobat Pro Review of Accessibility

  • Compatible with Conventional Assistive Technology – Screen Readers, etc.

  • Provides Built in Accessibility Accommodations

  • Facilitates Accessible Authoring

  • Create Accessible PDF Documents and Forms

  • Produces Standards Compliant Content

  • Creates Accessible PDF Documents from Other Sources
