How to make the laser marking machine make photos more clear

To set the appropriate DPI parameters, generally 100~500, according to the spot size setting, the larger the DPI value, the smaller the laser spot, the finer the picture. The power of the laser should also be set properly, the laser power is too large, and the image is white. The laser power is too small, the image is too dark, and more experiments should be done according to the actual effect.

Normally, the higher the selected picture pixel, the better.
