On the basis of add random multiple color and generate three-dimension code color image, it is ensured that the randomness of three-dimension code ensure that anti-fake
Function；Again on the basis of three-dimension code color image, different colours corresponding vector marking path is obtained according to colouring information, as
Classification storage information；It is random using laser output laser beam marking in Multi-layer anti-counterfeit module according to classification storage information
Three-dimension code；One timing of marking time, the based on the received output power of classification storage modulates information laser or laser output
One timing of power, classification storage information adjusts the marking time based on the received, can quickly exist after completing a machining path
Multi-layer anti-counterfeit module subscript carves three-dimension code deep mixed, with concave-convex sense, greatlys improve relative to tradition machinery processing
Processing efficiency.Wherein during marking, output power is used using the method ratio of the output power of modulated in real time laser
Certain method for adjusting the marking time is more efficient.
It to enclose is unit marking with the marking path that spiral back tracking method generates, the marking path that Contour filling method generates is to sweep
Retouching line is unit marking, and spiral back tracking method is obviously shortened compared to Contour filling method, marking distance, and marking efficiency can be mentioned obviously
It rises.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should all include
