Laura,
Having columns enabled when recognizing tables will cause information which
should appear on the same line to be placed further down the page. For
example, when recognizing a table of contents, if columns are enabled, then
all of the page numbers will appear after all of the chapter titles instead
of each page number being placed on the same line as the chapter title.
BTW, FineReader is up to version 8.
As for reasons to use one OCR engine over another, each has its own
strengths and weaknesses. For example, it was my experience that FineReader
7 did a better job at recognizing punctuation, and the previous version of
ScanSoft did a better job at recognizing larger text or text in headers. My
personal preference then was to use FineReader since I preferred to look for
issues with text instead of punctuation. I've only had the current versions
of the OCR packages for a couple of weeks, so I can't say what improvements
had been made to either package.
I think the best advice to give you would be to try both, and either settle
on one which tends to do the best job on the type of books you like to scan,
then switch to the other if you encounter a problem. Or to give each a try
every time you start a new scanning project. BTW, K-1000's Optimization
feature is meant to help you with the latter, if you happen to have K-1000.

Two questions:
Why do you disable columns? Is it advisiable to do that allof the time?
I'm a newbie scanner so I'm learning invaluable tricks through this thread.
Also, why fine reader 7? Isee the different engines, but can anyone give me
an explanation as to the difference between them all and why one might be
better than another in different situations?
Thanks,
Laura
