Scanning and OCR with Acrobat

Acrobat can import scanned images (best in TIFF) or interface with any TWAIN driver to scanners and digital cameras. This imports only pixel data, so a text recognition step is needed to create searchable text and possibly reduce file size. Acrobat calls this OCR step paper capture.

  • File > Import to bring in image data
  • Tools > Capture to set up your capture preferences. Normal will convert image data to text. Both will keep the image visible and the text data hidden behind it, so find-operations do take you to the right location in the document.
  • Find Next Suspect (Ctrl-H) to review the words Acrobat thinks it may not have recognized correctly. You will see a magnified version of the word/pixels in question. In the actual document, the word Acrobat chose is highlighted. Accept it or type over it.
  • If good looks are really important, you may need to go over most words/lines and edit their font properties with the touchup-text tool, a very lengthy and tedious process. Probably retyping in a word processor would be faster.
