7. On the toolbar at the top of the Image window, click Read.
Now if ABBYY FineReader encounters an unknown character, a Pattern Training dialog box will display the unknown character.
8. Teach new characters and ligatures.
A ligature is a combination of two or three "glued" characters (for example, fi, fl, ffi, etc.). These characters are difficult to separate
because they are "glued" during printing. In fact, better results can be obtained by treating them as single compound characters.
Note: Words printed in bold or italic type in your text or words in superscript/subscript may be retained in the recognized text by
selecting the corresponding options under Effects.
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 will function
only within one word.
Important!
● You can only train the system to read the characters included in the alphabet of the recognition language. To train ABBYY
FineReader 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. From the Tools menu, select 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 but diverse 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 around it and as the number 0
if there are digits around 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 use the same pattern later, save the current document options to a file.
5. To recognize texts set in a different font, be sure to disable the user pattern by selecting the Do not use user patterns option in
Tools>Options…>2. Read.
