No

read the thread I just posted



The thread says:
As you can see from 1ajs's 4800dpi example, even these could "nearly do".

Also I think saving uncompressed 9600 DPI from 4800x9600 scanner may be
much better.

Could it be tried?

I've calculated fiche DPI for posted DEC images (TA11 bootstrap), it's
about 3200.
1110*16/5.75 = 3089 DPI
You can add a few percents for margins.



DEC crammed a lot of frames on a fiche sheet
