20.11. Digitally Signed

Digitally Signed:   Documents that are digitally signed will not be processed by Symphony OCR because adding OCR information to these documents would invalidate the digital signature.   If you wish to have these documents OCRed anyway (and are OK with invalidating the digital signature), enable the Analyzer > 'Process digitally signed PDFs' option.  Note that rolling the document back will recover the original digital signature if you ever need to prove that the document has not been materially modified by OCR.
