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. 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. 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. 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). Place blank pages if you want to save your document to multiple output files using the `Create a new file at each blank page' option. If you have a document longer than the capacity of your ADF, select `Automatically prompt for more pages' in the Process panel of the Options dialog box. Then a dialog box lets you add further page batches and signal when all pages are scanned. 50 T U T O R I A L : PROC E S S I N G D O C U M E N T S You can scan double-sided documents with an ADF. For non-duplex scanners, select `Scan double-sided pages' in the Scanner panel of the Options dialog box. Then you can scan the document in just a few passes, with even pages grouped together and odd pages also grouped. OmniPage Pro will merge the pages for you. Scanning long documents without an ADF You can scan multi-page documents efficiently from a flatbed scanner, even without an ADF. [. . . ] If an area is not enclosed by a zone, it is generally ignored during OCR. Reidentify zone types and contents, if necessary, and perform OCR on the document again. x Adjust the brightness and contrast sliders in the Scanner panel of the Options dialog box. You may need to experiment with different settings combinations to get the desired results. [. . . ]
