Bar Codes Not Read from Imported PDF Files

Issue

Bar Codes are not being successfully read by the Standard Bar Code (SBC) engine or the Enhanced Bar Code (EBC) engine from images that originated as imported PDF files.

Cause

The PDF Import engine in Kofax VRS / ImageControls renders imported PDF files as 200dpi TIFF images.  If the bar codes contained in the PDF file were created electronically using a bar code font or if they are included in embedded images with a higher resolution, the conversion to 200dpi could drop a bar code element or merge two elements together, rendering the bar code invalid.

Solution

Rendering imported PDF Files as higher resolution (such as 300dpi) TIFF images can ensure that the bar codes are rendered correctly, preserving their readability.

To configure PDF Import to render the pages as 300dpi TIFF images:

1. Stop all applications and services that use Kofax VRS / ImageControls
    
2. Navigate to C:\ProgramData\Kofax\Vrs
    
3. Create a new text file called ModConfig.ini (if one does not already exist).
    
4. Open ModConfig.ini in a text editor such as Notepad
    
5. Add the following lines (if they do not already exist):

   [KDLWrapper]
   MINRENDERINGDPI=300
   MAXRENDERINGDPI=300
   

6. Save the changes to ModConfig.ini
