Klippet fra manualen - Acrobat 7 Pro side 139: For most pages, black-and-white scanning at 300 ppi produces text best suited for conversion. At 150 ppi, OCR accuracy is slightly lower, and more font-recognition errors occur; at 400 ppi and higher resolution, processing slows and compressed pages are bigger. However, if a page has many unrecognized words or very small text (9 points or smaller), try scanning at higher resolution. Scan in black and white whenever possible. Ole K.
