As previously stated, FineReader can read texts set in
practically any font regardless of print quality. Consequently, no
prior training is normally required before recognition can take
place. FineReader, nevertheless, features a number of user pattern
recognizing large volumes (more than a hundred pages) of texts
of low print quality.
Tip: Use Train User Pattern mode only if one of
the above applies. In other cases you may obtain a slight
increase in recognition quality, but the time and effort involved
will probably outweigh the benefit received.
Pattern training works as follows. One or two pages are
recognized in training mode, and, subsequently, a pattern created. FineReader then
uses this pattern to aid recognition of the remaining text.
Sometimes two or even three characters may get "glued" together,
and FineReader may be unable to enclose each character in an
individual frame to separate them. If this proves to be the case
(i.e. you cannot move the frame so that it contains only one whole
character and no other character parts), you can train FineReader
to recognize the whole inseparable character combinations. Examples
of character combinations frequently found glued together include
ff, fi, and fl. Such combinations are referred to as ligatures.
A pattern is only useful in the case of documents that have the
same font, font size, and resolution as the document used to create
the user pattern.
Each pattern is created for a particular batch. Consequently,
if a batch is deleted, its user pattern is also deleted. Patterns
can, however, be copied into other batches. To transfer a user
pattern to another batch, simply save the batch options in a
If you switch to recognizing texts set in a different font,

Tools>Options menu, in the Training group. The

Click the 2-Read button.
Train your pattern - recognize
one or more pages in Train user pattern mode.
Trained characters are saved in the default pattern. Once you have
completed training the pattern, FineReader will save the pattern
(Default.ptn) in the current batch folder.
Deactivate training mode (click the Use user pattern
button on the Recognition tab).

To create several patterns for the same batch, use the Pattern Editor dialog
(click the Pattern Editor button on the Recognition
tab or select the Tools>Pattern Editor menu item). Create
a new pattern (click the New button in the dialog) and
select it (click the Set Active button). Working with a
created pattern is no different to working with a default pattern
(see steps 1-5). Keep in mind,
however, that only one pattern may be active at any one time.
If you've created several patterns for the same batch, the
active one will be the pattern that was last created. The active
pattern name is displayed in the status bar. To activate another
pattern, select the pattern of your choice in the pattern list in
the Pattern Editordialog
(Tools>Pattern Editor menu) and click the Set
Active button. Then click the Use user pattern button on
the Recognition tab,
Tools>Options menu, in the Training group.
If the Use built-in patterns option is set, FineReader
will read all texts using its built-in patterns and stop only at
uncertain characters. If you are training the system to read
decorative and/or non-standard fonts (for example, Tibetan) the use
of in-built patterns may result in characters being read
incorrectly. If the latter occurs, disable the use of
in-built-patterns (clear the Use built-in patterns checkbox
on the Recognition tab) and train the system to recognize
each unknown character it is likely to encounter.
