1D barcode quality inspection

[MikeAM]

Hello,

I have a question about

  

.

I created Code39 online, so my image of the code is pretty clear.

But when I use 1D barcode grading in VBAI, it says overall grade is D.

I also tried to simulate defect on the code but it seemed to be no different.

Anyone can help?

My purpose is to use grading to justify whether printed barcode has any defect on it or not.

(Label got scratches or wrinkle)

 

Thank you.

Mike
