In terms of color selection for QR codes, dark modules generally use black, coffee, dark blue, etc., while light modules generally use white, light yellow, beige, etc.

Due to the limitations of traditional barcode readers in terms of technology and performance, black QR codes and white backgrounds are generally used in combination. Changing the color combination may result in the inability to read the QR code or require higher performance from the barcode reader device.

So, if the color of the material's QR code changes, how will the code reader face the challenge? In this issue, Xiao Ming will share with you the application of Meiji Smart Code Reader in reading black background and white QR codes~

Detection Scenario

The material is the two-dimensional code on the graphene heat sink, with a black background and white code. The surface of the two-dimensional code may have small areas of dirt, and it is required to use a code reader that will not be affected by dirt and can read stably

Analysis of key points for selecting code readers:

1. The location of dirt is not fixed

2. The position of the QR code may have a left-right offset phenomenon

3. The recognition speed requirement is within 50ms to prevent the code reading speed from not keeping up with the servo running rhythm

4. The customer uses Ethernet communication on site and requires the code reader to support Ethernet communication

5. Due to limited equipment space, it is necessary to adapt to small-sized code readers
