Introduction:
Recently, some friends questioned me about how to laser engraver black on metal. So we are here to give you an easy way to find the way to laser engrave black on the metal.
The main point of laser engraving dark on the metal is to keep the propel focus inside the right one.
With the same parameter, in the propel focus, it doesn’t engrave the black; inside, it burns the metal with greater power.
Only until we find the suitable focus for back marking will it give the pretty black.
So how do we find the right focus to engrave dark?
