18.5. Recommended Scan Settings

How should I configure my scanner for optimal use with Symphony OCR?

For best accuracy, we recommend scanning at:

  • 300 dpi for black and white images, or
  • 200 dpi for grayscale and color

Note: 200 dpi will still work for black and white, but accuracy will drop slightly.  Below 200 dpi, accuracy drops off sharply for smaller fonts, and is not recommended.  Above 300 dpi, accuracy does not measurably improve (and results in much larger files that are slower to process).
