Customizing OCR

Training OCR for Special Characters

A training file is a set of pre-recognized text characters that OmniPage 
Pro compares with characters on a page image during OCR. You can 
create a training file for special characters that might normally be 
difficult to recognize such as the copyright symbol © or the registered 
trademark symbol ®. 

To create a training file:

1

Open the image file or scan the page that includes characters 
you want to train. 

2

Create zones around the text that you want to train.

3

Set Train OCR as the command in the OCR button’s drop-down 
list.

4

Click the OCR button or choose Train OCR in the Process menu.
OmniPage Pro analyzes the document and then opens the Train 
Characters dialog box. 

5

Double-click a character you want to train. Or select it and click 
Specify. 

Most characters do not need to be trained. Look for uncommon 
characters such as the copyright symbol ©. 

Do not train OmniPage Pro for regular characters because it may 
interfere with recognition. 

Original character image

OmniPage Pro’s 
interpretation of the image
