General PDF Accessibility Tips
PDFs must be accessible to ensure the widest possible readership and to allow all students to participate fully in online courses. It's easiest to produce an accessible document by creating it in WORD or PowerPoint or HTML and then to save it as a PDF.
First: Scan with OCR “Optical Character Recognition.”
Make sure your phone app produces "OCR" scans.
"Dropbox Enterprise License" version allows for OCR scans.
CUNY users login to Dropbox using CUNYFirst login for the enterprise version.
Second: Apply Adobe Acrobat Pro “Accessibility Checker” (instructions below) to address accessibility issues.
Third: Provide a WORD transcript of a scanned PDF if the PDF is not accessible.
Adobe Acrobat Pro DC Accessibility Checker
Adobe Acrobat Pro DC has an "accessibility checker" to:
- Check that a PDF is OCR.
- Optical Character Recognition mean each letter is recognized and text is searchable.
- Check that a PDF is “tagged” with hidden labels.
- Tags describe the document structure (e.g. header, paragraph, table cell).
- Screen readers use tags to orient readers with audio cues to the document.
- Check the "reading order" of the PDFs (especially important with documents containing columns).
- Check for "alt-text" alternative text to describe images and graphs for screen readers.
Tip: limit black edges on scans to reduce the toner required to print a scan.
