This document describes how accurately different types of text are scanned in and converted in an Optical Character Recognition OCR program.
Accuracy of converted text in OCR programs
Optical character recognition programs convert some text more accurately than other text. Because OCR technology is never perfect, proofread all converted text carefully to ensure the characters have been correctly interpreted.
These types of text convert most accurately:
- Text in standard fonts
- Text in 9-point font or larger
- Crisp, clear text
- Black text on a white background
These types of text might convert less accurately:
- Text close to non-text elements, such as bullets, lines, or graphics
- Text in spreadsheets, tables, or forms
- Letters that have gaps, that "bleed" along their edges, or that touch other letters
- Underlined text
- Text on colored paper
- Handwriting cannot be converted.
