Data Matrix ECC200 rectangular bar code recognition rate improvment with the Enhanced Bar Code engine


QAID # 13572 Published

Question / Problem:

How to improve bar code recognition rates when using the Enhanced Bar Code (EBC) algorithm to read rectangular (ECC200) Data Matrix bar codes

Answer / Solution:

Yes. Starting with VRS 4.5 SP1, the Enhanced Bar Code (EBC) algorithm can be further fine-tuned in order to enhance bar code recognition for rectangular (ECC200) Data Matrix bar codes by editing the KBarMode.ini file.

To enable rectangular Data Matrix bar code recognition:

1. Navigate to C:\ProgramData\Kofax\Vrs

2. Create a new text file called KBarMode.ini if it does not already exist

3. Open KBarMode.ini in a text editor such as Notepad

4. Add the following lines if they do not already exist:


5. Save the changes to KBarMode.ini

6. Restart all applications and services that use VRS / ImageControls.


NOTE: Enabling recognition for rectangle bar codes in the KBarMode.INI file can reduce overall bar code recognition speed and accuracy.
