Subject: RE: Sutton book - Reply
I use OmniPage 10 and rarely have errors in character recognition and this
is not the latest version! When I do get errors they are related to weird
fonts, fancy headlines, poor copies, stray marks, and so on. Sutton's book
would not present these problem as far as text is concerned.
