355nm uv laser engraving paper and cardboard

The engraving of cardboard also depends on the material, and the result is different from the usual engraving of the CO2 machines. While the CO2 machines carbonize the surface of the carboards or paper materials, the UV generate a chemical reaction making a marking over the material surface, it is for that reason that we can engrave with white color over cardboard surfaces, and if we want to engrave on black cardboard, we still can get clear contrast, If you have more questions about the engraving of this material, get contact with us.
