I have a lot of manuals I want to scan and am trying

best format. I'd like some opinions on the following scans of a 128-page
Franklin AceWriter manual.
On the low end is a pdf of bitmap images. It's hideous, but only 3.5 MB.
The high end is a 40 MB pdf of jpeg images. This one's easy on the eyes,
but is an awfully large download and I'm wondering if it might not print
as nicely as the bitmap.
Just test it. For scanning, I usually dont *care* about
the size,
since we're doing preservation, we get to do it *once*. So, I set
things to "max quality" and scan. Once that is done, usually turn
them into PDF with Acrobat, in "prepress quality". In your example,
this would yield a PDF of about 30M. I consider that very acceptable
for a scanned manual of good quality. If someone wants a smaller one,
one can always reduce it later. The opposite (sending out low-qual
ones and then make them look better) doesn't work so good.
Thoughts? Which of the three would you most want to
download?
The best one :) Disk space (or even bandwidth) issues are a problem
of days gone, I'd say. Downloaded PDF's easily fit on CD-R's, which,
at $0.10 a piece, come cheap...
Cheers,
Fred
