To go back to a previously trained character, click the Back button. The frame will jump to
its previous location and the latest trained "character image – keyboard character"
correspondence will be removed from the pattern. The Back button navigates between
characters of one word and will not navigate between words.
Important!
• You can only train ABBYY FineReader to read the characters included in the alphabet of the
recognition language. To train the program to read characters that cannot be entered from the
keyboard, use a combination of two characters to denote these non–existent characters or copy the
desired character from the Insert Character dialog box (click
to open the dialog box).
• Each pattern may contain up to 1,000 new characters. However, avoid creating too many ligatures,
as this may adversely affect OCR quality.
Selecting a User Pattern
ABBYY FineReader allows you to use patterns to improve OCR quality.
1. On the Tools menu, click Pattern Editor….
2. In the Pattern Editor dialog box, select the desired pattern from the list of available patterns and
click Set Active.
Some important points to remember:
1. Rather than differentiating between some similar yet different characters, ABBYY FineReader
recognizes them as one and the same character. For example, the straight ('), left (‘), and right (’)
quotes will be stored in a pattern as a single character (straight quote). This means that left and
right quotes will never be used in the recognized text, even if you try to train them.
2. For some character images, ABBYY FineReader will select the corresponding keyboard character
based on the surrounding context. For example, an image of a small circle will be recognized as the
letter O if there are letters immediately next to it and as the number 0 if there are digits next to it.
3. A pattern can only be used for documents that have the same font, font size, and resolution as the
document used to create the pattern.
4. To be able to use a pattern later, save it to a file. See Working with a FineReader Document for
details.
5. To recognize texts set in a different font, be sure to disable the user pattern by selecting the Use
only built–in patterns option in Tools>Options…>Read.
Editing a User Pattern
You may wish to edit your newly created pattern before launching the OCR process. An incorrectly
trained pattern may adversely affect OCR quality. A pattern should contain only whole characters or
ligatures. Characters with cut edges and characters with incorrect letter correspondences should be
removed from the pattern.
1. On the Tools menu, click Pattern Editor….
2. In the Pattern Editor dialog box, select the desired pattern and click the Edit… button.
3. In the User Pattern dialog box, select the desired character and click the Properties… button.
In the Properties dialog box, type the letter corresponding to the selected character and select the
desired font effect (bold, italic, superscript, or subscript).
To delete a character that has been trained incorrectly, select the character and click the Delete
button.
