Scanning Tips
OCR results will be poor if an image is not scanned properly. Remember
the following tips when you scan:
• Take the color and quality of your document into account when
scanning.
High-quality documents return better recognition results than
low-quality documents. Shaded, colored, or low-quality
documents may result in poor recognition accuracy unless
adjustments are made before scanning.
See “What is the quality of the original document?” on page 85
for more information.
• Always try to scan an original document instead of a copy.
• Make sure the page is properly aligned in the scanner.
• Check the scanner glass for dust, smudges, or scratches. Clean it
if necessary.
• Make sure the proper settings are selected in the Scanner section
of the Setting Panel before scanning.
See “Scanner Settings” on page 66 for more information.
OmniPage Pro cannot recognize white text on a black background. If
your page image has this type of text, you can reverse the black and
white elements so that the text is black and the background is white. See
“Inverting an Image” on page 54.
