For OCR, it may depend on the OCR software, but for almost everything I have
found that 300 dpi and gray-scale (8 bits per pixel) JPEG works best.
Grayscale is definitely better than black-and-white (1 bit per pixel) for
reproduction that is indistinguishable from the original, but for some OCR
software, black-and-white line art (1 bit per pixel) may work better.
