So let's say we had to scan in order to change and add stuff. And if a novice did the work then he'd be hit-n-miss on the supersctipt and such becuase he's using a COMPUTER, of all things.
So there are still ALTERED documents.
Exactly. You would OCR Scan a document that was particularly long (i.e., a catalog of information) because you needed to edit/update the information. Mostly useful in updating old index info without having to type for days from analog "hard" copy into your "new" computer software. Took more time to fix the OCR mistakes than to just retype the damn stuff.
You would never use OCR to simply make a copy.
PLUS: crumple marks on the PDF wouldn't show up on an OCR scan. Game.Set.Match.
