Laser Marking QR Code Is Not Clear?

As shown in the picture, the laser marking QR code in the middle is not clear, and it feels like the QR code is obviously engraved into the product. How to adjust this?

The picture shows that the QR code may be filled too densely or the power is too high. It is recommended to modify the filling density or use another pen number for the laser parameters of the QR code, to reduce the power of this pen number.
