As I indicated in my post, 300 dpi is indeed inappropriate for OCRing small type. Since the original question only mentioned "books" I thought it best to not make the assumption of small text, since hi-res scanning is slower, and produces much larger files. >An 8x10 1 bit TIFF at 300 ppi is 320k > >An 8x10 1 bit TIFF at 600 ppi is 860k - I guess I don?t see any big deal >with the file size being an issue.
