Am I right in thinking that a home flatbed scanner has
absolutely no
hope of providing the resolution needed to scan microfiche?
I've seen some microfiche readers / microfilm readers which by means of
optics could enlarge a single page to Legal or A4 format, possibly on a
photocopier drum (or however that works). Then you could print a hardcopy.
Mumble mumble headscratch :
suppose we have 80 chrs (fontsize 10, fixed width) on an A4 line. Each
characters would need (e.g.) 12 pixels. 25% for margin, overhead etc.
So, 16 A4 pages would be (16 x 80 x 10 x 12 x 1.25) pixels = 192.000.
192.000 pixels on a fiche, about 12 (?) cm wide, would give a density of
16.000 pixels per cm = 40.640 pixels per inch.
Hardly obtainable, I would say ...
