Up to 400 dpi, 2,000 frames/hour? Yee-haw!
400 dpi does not sound at all adequate. If we were to assume that the
microfiche were to be 1/10 (linear) the size of original paper (.85" x
1.1"), then we would want 10 times the resolution (linear) per inch
that we would want for original paper. Therefore, if the microfiche
were to be 1/10 (linear) the size of paper (approx 1" square per
frame), then that would be like scanning pieces of paper at 40 dpi.
Anybody know offhand what the conventional sizes are for microfiche?
(it's certainly less than 1" for the height of a frame!)
My guess is that the 400 dpi resolution is after enlargement. According to
the first Google hit, the 460XL supports 20:1 and 24:1.
Does 400 dpi seem adequate for most printed matter?
