Why the radium carving machine can only print the monochrome logo

Because of the effect of laser engraving laser marking technology is a deep substance through the surface material evaporation, or by light can cause chemical and physical changes of the surface material or burned part of the material through the traces of light, and "carved out" marks, or through the light burned part of the material, showing required etching of graphics and text

So the display of LOGO is the bottom color of the leakage of metal, so it can only be printed out of the monochromatic sign.
