These helpful hints will increase OCR accuracy in OmniPage Pro:
Choose Options
All... in the Tools menu and click the tab in the Options dialog box for the settings you want to change:
Adjust the Brightness and Contrast sliders in the Scanner tab if you are scanning pages with text on colored or shaded backgrounds.
Select Automatically correct page orientation in the Process tab.
Select Automatically straighten page image in the Process tab.
Move the OCR Method slider to the Most Accurate end in the OCR tab. This will improve OCR accuracy, but may increase processing time.
Select Use training file in the OCR tab to use a character training file to help recognize special characters during OCR. See Training OCR for more information.
Make sure zones are identified correctly before OCR. See Changing Zone Properties for more information.
To retain handwritten text, such as a signature, identify it as a graphic zone.
Try to use original pages when you are scanning documents. Typeset, high-quality printed page images return the best OCR accuracy. OCR accuracy may not be as good with lesser-quality pages.
Ask senders to select Fine or Best Mode when they send you a fax.
Page images should be free of notes, lines, or doodles. Anything that is not a printed character slows recognition, and any character distorted by a mark will be unrecognizable. Try not to include such marks in zones, or enclose them in an Ignore zone type.
Text in page images should be reasonably clean and crisp. Characters should be separated from each other and not blotched together or overlapping.
Text in page images should not be underlined. It is difficult to recognize underlined text because the underline changes the shape of descenders on the letters q, g, y, p, and j.
If you plan on reopening and performing OCR on a color or grayscale image, save it as an OmniPage Document (*.opd) rather than an image file. This is because color and grayscale image files are saved at a lower resolution than the originals, but OmniPage Documents retain the image resolution necessary for optimal OCR results.
