Nowadays, merchants are inseparable from the application of QR code for the payment, shopping and eating. The continuous development and innovation of the QR code has won the love of people from all walks of life and enterprises. With the maturity of laser marking technology, many companies have carved their own company's QR code into the product to facilitate subsequent contact and promotion. How do we accurately engrave the QR code to our own products?

 

As is known to all, the laser marking machine marks the surface of various materials by laser beam, the effect is clear, the characters are delicate and exquisite, and easy to recognize. At present, it has been widely used in various industries, materials, devices, spare parts and daily necessities. Laser marking machines make barcodes, and QR codes have become an indispensable practical technology in people's production and life.

 

The laser marking machine makes two-dimensional code barcodes. In fact, sometimes we will find that the barcodes produced by the barcodes are very fresh, but the scanners can't read them. What is going on here?

 

For example: red can only be used as the base color of the QR code barcode, and can not be used to make the strip color. Because the scanner emits red light, the red light illuminates the red code and produces a strong reflection, similar to the white light. The requirement for barcode QR code recognition is that the empty reflection is strong and the reflection of the code is weak. Therefore, the red color that is strongly reflected by the red light is only suitable for the short color (base color), and is not suitable for the color of the code. The bar code QR code is very strict with the color, not all colors can be used to print the code. The colors that can be made are white, yellow, orange, and red. The colors that can be made are black, blue, dark green, and dark brown. Other colors are not allowed.

 

Knowing this, we will produce the QR code and barcode when we use the laser marking machine. We should try our best to produce according to this requirement. Sometimes we can solve it by the method of Yin carving. These require us to constantly think about ways to constantly improve our actual operation level.
