Error/Warning: increase resolution to improve recognition of small text

Symptoms

After updating Abbyy FineReader Server to the latest version and following message was received: Error/Warning: increase resolution to improve recognition of small text.

Also, the same warning message that indicates that increasing the resolution is needed may appear after changing the resolution in the scanning station option when it goes through the verification station.

Cause

As per the message shown, it appears due to the document resolution.

Resolution

Please check the following recommendations:

  • When scanning regular texts with font sizes 8-10 points, it is recommended to use 300 dpi resolution for OCR. All ABBYY technologies are tuned for that resolution.
  • For smaller font text sizes (8 points or smaller) we recommend using a 400-600 dpi resolution.

More details on the optimal settings for OCR are available via the following link:
