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.
