I'm not really too sure what the best method is - I used to be a big believer in
jpg, but I think it's no good for text or line stuff like patch sheets or
schematics.
I don't really know about tiffs, but gifs are pretty good for this kind of stuff,
you can cut the file size right down while keeping readability, by reducing the
colour depth as much as you can - down to two colours is best if you can manage
it. My suggestion is to scan at say 400dpi, clean up the image (colour replacer
in Paint Shop Pro is pretty good for removing erroneous shades of white etc.,
which cuts file size amazingly), decrease to 2 colours (or as few as will
maintain legibility), and save as gif.
I spent at least an hour trying to optimise, resize, resample, re-everything one
of the patch sheets in several attempts to get Acrobat to convert it to text, but
to no avail.
Perhaps you might want to try the method above and post one to the site (I'm on a
fast connection at work) and I could try converting that one?
Though I don't really know how we'd go about making the tables in a text file...
but first things first ; p
