Adjusting the Image Quality
The recognition results depend a great deal on the image quality of your documents. If you're scanning
very low-quality documents, Readiris will not be able to recognize them properly.
The reason for this is that Readiris works by converting pictures of text characters into actual text
characters. If your documents are too dark, the characters fade into one another and create black spots.
If your documents are too light, the text characters might be broken. Consequently, Readiris will not be
able to recognize them.
Example 1: text is too dark
Here, the letter shapes begin to fill in and become fuzzy. Letters like a, e, and o are almost completely
blurred.
Example 2: text is too bright
Here, the text characters start to show gaps and incomplete shapes.
To improve the recognition results:
Check the Scanner Settings and make sure your documents have been scanned in a resolution of
300 dpi and in color.
If that's not the case, re-scan your documents using these settings.
Then access the Image Adjustment options:
Click the Adjust icon on the Image and Layout Editing toolbar.
