Dear All, I need to scan a textbook, black and white. Could someone please advice me about the settings (resolution, brightness, etc.) in order to get a small pdf file? Thanks in advance, Paul
Some time ago, on this very list I believe, someone posted the results of their OCR experiments. It seems that accuracy peaked at about 300 dpi if I remember correctly, and actually dropped off below that. I don't remember what OCR engine he was using. I wouldn't scan the textbook directly to pdf, even if your only intention is to reprint it. In that case, just go to a photocopier. OCR and reformatting the text will look much nicer. If it's English text, then it shouldn't be much of a problem. Dotan Cohen http://lyricslist.com/ http://what-is-what.com/
