If all you are doing black&white scans, there is an easier way:

For my own archival scanning:
- scan at 600 dpi to bilevel TIFF
- convert TIFF to use fax G4 compression
- tar up the TIFF files for archival
- feed the TIFF files to tumble to produce PDF for archival
- feed the TIFF files to a conversion chain that emits DJVU for
archival
The scans are pretty compact and I end up with the data in three
different open formats, so the odds of being able to read them a few
years down the road should be reasonably good ;-)
Side benefit: due to the rather high resolution, the prints done from
the archival PDFs tend to be much better than Xerox copies (printing
with a 600 dpi laserjet). And the resolution is high enough to get
reasonable results for OCR, when needed.
Kind regards,
Alex.

Digging up an old thread, but for a good reason.
I'm trying to scan some pages from an IBM Tech Ref. A friend needs the
pages on the 5161 expansion unit.
I've got 400dpi TIFF images. But tiff2pdf is giving me PDF files that
are much lower quality than what I'm putting in. After 2 or three hours
I don't have a solution and I'm just mad. :-(
What is the trick on tiff2pdf to get higher resolution output? Hi guys,
I'm after a program that can convert TIFF files into PDFs. I've seen Eric
Smith's "Tumble" app, which works great... but only for B&W TIFFs.
While I
I've used tiff2pdf for many years with great success. It offers
various compression options, and the output has always been excellent.
Unfortunately, I can't help you on the OCR side.
