QR codes are a common method of information transmission and data storage. QR codes appear on various packaging, product casings, and PCBs. As a high-precision and efficient marking equipment, laser marking machines are also expanding in application fields. They are used to mark QR codes on various materials. So, the QR code of 2mm*2mm is so small, can laser marking equipment print it?

The accuracy of the laser marking machine can reach 0.02mm, far exceeding that of other marking equipment. The line width at the micron level can print characters, barcodes, and QR codes that cannot be marked by other equipment. This is also one of its advantages, and the printed QR code is clear and free of burrs and can be easily recognized by mobile phones or professional scanning instruments.

Generally speaking, the larger the size of a QR code, the greater the amount of information it contains, but it also increases the difficulty of recognition. The printing range of the laser marking equipment can be adjusted as needed. Therefore, as long as the printing range of the marking machine can cover the size of the QR code, the QR code can theoretically be printed.

Whether a QR code with a size of 2*2mm can be printed depends on the specific laser marking equipment model and parameter settings. Some high-quality marking machines have high-precision, high-speed printing capabilities and higher precision. They can easily handle small size QR codes such as 2mm*2mm, such as Purple Light, or picosecond models. Some low-end or simple laser marking equipment may not be able to meet such accuracy and range requirements.

Since the QR code encodes information through black and white graphics, sufficient contrast and clarity need to be ensured during printing to facilitate identification by the scanning equipment. At this time, not only are there enough technical requirements and configuration requirements for the laser marking machine, the material itself will also have an impact on the marking effect, such as the hardness and density of the material. Some materials will burn as soon as the laser is applied, which is not suitable for marking a clear QR code. But if you mark it on a plastic shell or PCB board, there is no problem.

To sum up, whether the laser marking machine can print a 2mm*2mm QR code depends on the specific equipment model and parameter settings. If the printing range and accuracy of the laser marking machine can meet the requirements of QR codes, and has appropriate power and focus adjustment functions, and the material is suitable for printing codes of such a small size, then users can be met. needs.
