With the development of laser marking machine, the demand for two-dimensional code laser marking machine is constantly expanding.
Especially in the advertising tag or packaging industry, a variety of two-dimensional code, bar code, date, number, etc., require laser equipment Penma mark.
We refer to the two-dimensional code, refers to the use of a specific geometry according to certain rules in the plane (two-dimensional direction) distribution of black and white graphics, used to record data symbol information. Using a number of binary corresponding geometry to represent the numerical value of information through the image input device or photoelectric scanning device automatically read in order to achieve automatic information processing, but also has the ability to automatically identify different lines of information, and deal with changes in graphics rotation point.
Well, in today's era of science and technology, two-dimensional code has a very important significance. Some packaging industry will choose two-dimensional code to replace the previous bar code as a new production information; some manufacturing companies will use two-dimensional code swept away for each product for a detailed page description.
Through the laser marking machine, these marks can be a variety of accurate, durable marking, making these product information after the laser marking is not wrong, not fake.
