Input from scanner You must have a functioning, supported scanner correctly installed with OmniPage Pro. In making your choice, there are two main considerations: Which type of output do you want in your export document?x Which mode will yield best OCR accuracy? x Scan black and white Select this to scan in black-and-white. This is not suitable if you want color in your output document, nor if you want pictures to look like socalled 'black-and-white' photographs: they need grayscale scanning. For best OCR accuracy, use this for crisp black texts on a white or light background. Black-and-white images can be scanned and handled quicker than others and occupy less disk space. Scan grayscale Select this to use grayscale scanning. Choose this to keep `black-andwhite' photographs in the output document. For best OCR accuracy, use this for pages with varying or low contrast (not much difference between light and dark) and with text on colored or shaded backgrounds. Scan color Select this to scan in color. Choose this if you want colored graphics, texts or backgrounds in the output document. For OCR accuracy, it offers no more benefit than grayscale scanning (for a given resolution), but will require much more time, memory resources and disk space. DE F I N I N G T H E S O U R C E O F P A G E I M A G E S 49 Brightness and contrast Good brightness and contrast settings play an important role in OCR accuracy. Set these in the Scanner panel of the Options dialog box. The diagram illustrates an optimum brightness setting. After loading an image, check its appearance. If characters are thick and touching, lighten the brightness. If characters are thin and broken, darken it. Then rescan the page. Unsuitable Tolerable Good Best Good Tolerable Unsuitable Scanning with an ADF The best way to scan multi-page documents is with an Automatic Document Feeder (ADF). [. . . ] If IntelliTrain was running, try turning it off ­ on some types of degraded documents it may not be able to help. 86 TECHNICAL INFORMATION If you use True Page as the Text Editor view or for export, recognized text is put into frames (formatting boxes). Some text may be hidden if a frame is too small. To view the text, place the cursor in the text frame and use the arrow keys on your keyboard to scroll to the top, bottom, left, or right of the frame. x Check the glass, mirrors, and lenses on your scanner for dust, smudges, or scratches.
