The structure types for lists in PDF documents are: L - the List tag, which contains one or more LI tags. LI - the List Item tag. List item tags can contain LI_Label and LI_Title tags. LI_Label - the list item label. Contains distinguishing information such as a item number or bullet character. LI_Title - the list item title. Contains list item content, or in the case of a nested list, it may contain additional List tag trees. </p> <p>Int-Adv Document Accessibility 1/17/2013Creative Commons-Some Rights ReservedList Tags</p> <p>Int-Adv Document Accessibility 1/17/2013Creative Commons-Some Rights ReservedMaking scanned documents accessibleScan the documentOnce the scan is complete use Document &gt; OCR Text Recognition &gt; Find first OCR suspect to look for problems in the conversion.Correct any problems you find and repeat the process as necessary.Add alt text to any graphic images.Repair the structural elementals such as reading order.Then run the accessibility check to see if anything else needs your attention.Creative Commons-some Rights Reserved</p> <p>Intro to Document Accessibility 1/17/2013Scanned DocumentsOCR Process: If the PDF file is a scanned image of text, an Optical Character Recognition (OCR) process must be followed.</p> <p> In Acrobat Pro 9.0 select Document &gt; OCR Text Recognition &gt; Recognize Text Using OCR... &gt; then select all pages in document for conversion. </p> <p>In Acrobat Pro 11.0 Select Tools &gt; Text Recognition &gt; Find all Suspects &gt; In This File &gt; Select All Pages Creative Commons-some Rights Reserved</p> <p>Intro to Document Accessibility 1/17/2013Scanned Documents OCR Acrobat Pro 11.0Creative Commons-some Rights Reserved</p> <p>Intro to Document Accessibility 1/17/2013</p> <p>Scanned Documents - OCR VerificationOnce OCR has been completed Tags must then be added to the document.Once OCR conversion is complete each tagged element must be manually checked and verified.
