Section 5: Converting scans to accessible Adobe PDF content
In some instances, Recognize Text Using OCR can't recognize all the text. These instances relate directly to the clarity
of the scanned material. For example, Recognize Text Using OCR might interpret a smudge on a page as suspect text.
Similarly, the OCR dictionary in Acrobat may have difficulty identifying characters, so it considers them suspect or
questionable. You can examine, confirm, or correct suspect text in Acrobat either one suspect at a time or for all
suspects at once.
For detailed information on applying OCR and checking for OCR suspects in scanned PDF documents, see
"Creating Adobe PDF documents from paper documents" in Acrobat 7.0 Help.
Scanning a paper document to Adobe PDF
You can use a scanner and Acrobat 7.0 to scan a paper document directly to Adobe PDF by using the File > Create
PDF > From Scanner command in Acrobat.
You can apply OCR at the same time that you scan the document, or afterward by using the Recognize Text Using
OCR feature. If you apply OCR while capturing the scan, you must activate the Formatted Text & Graphics setting,
as previously described in "Applying OCR to image-only Adobe PDF scans" on page 29, so that Acrobat processes
both text and graphics. In this workflow, this setting is available when you click Settings in the Create PDF From
Scanner dialog box.
Applying OCR while scanning a document; click the Settings dialog box to select the Formatted Text & Graphics option and create an accessible
PDF document from the scan.
After applying OCR, you must verify the accuracy of the OCR by checking for OCR suspects.
For detailed information on scanning documents directly to PDF, applying OCR, and checking for OCR suspects,
see "Creating Adobe PDF documents from paper documents" in Acrobat 7.0 Help.
Note: If your enterprise has a large volume of legacy paper documents that have not yet been scanned and converted to
PDF, consider purchasing Adobe Acrobat Capture 3.0 and the Tag Adobe PDF Agent, so you can process them all at once
into searchable, tagged PDF archives. See
www.adobe.com/products/acrobat
for more information.
Converting TIFF or other image formats to Adobe PDF
Scanned files that have not been saved directly to Adobe PDF are generally saved in an image format, such as TIFF,
JPEG, or GIF. To bring these files into the PDF accessibility workflow, you can open them in Acrobat 7.0, save them
as PDF, and then apply OCR to convert the image to accessible content.
Acrobat 7.0 can open and convert BMP, GIF, JPEG, JPEG2000, PCX, PNG, and TIFF images. To open them, use
either the File > Open command or the File > Create PDF > From File command. When you apply OCR, be sure to
select the Formatted Text & Graphics option in the Recognize Text Settings dialog box, so that Acrobat can recognize
both graphics and text on the page. See "Applying OCR to image-only Adobe PDF scans" on page 29.
