White Lines Appearing on Barcodes when Previewed and Printed


When previewing or printing out a barcode from an SSRS report, a white line(s) will appear in the barcode. I have tried changing the font size, bar height, and the n dimension. Copying a previously working bar code onto the report does not work either.
The code in the barcode expressing is =Code.IDAutomation_SSRS_Code39(Parameters!PartNum.Value)
The PartNum is just an inputted parameter.

Operating System: Windows 10

Application: Visual Studio

Best Answer

The Native SSRS Barcode Generator uses the Unicode Image technique to draw the barcode. This issue is most likely only visible on the screen because screens have very low resolution, and when printed it should be accurate. The issue could be resolved by changing the font that is selected for the barcode field to "Consolas". If Consolas is already chosen, try "Courier New". You should also be able to change the point size to create a symbol that does not look this way on the screen.

As a last resort, If either of those do not work, refer to the Unicode Image link above and try the IDAutomaiton2D S font.
