With the rapid and continuous development of science and technology in the era, the Internet has developed more excellent, and the application of communication equipment software and two-dimensional code has become more active. The continuous development and innovation of two-dimensional code has won the favor of people from all walks of life and enterprises. Now, they are promoting their company’s information in the form of two-dimensional code. Not only that, for example, businesses can’t receive payment, shop, eat without the application of two-dimensional code. Since then, Many enterprises have carved their own QR codes onto their products to facilitate follow-up contact and promotion. How can we accurately carve the QR codes onto their products?
With the continuous development of laser technology, it is not difficult to carve the QR code into our own products. For the laser marking machine to make the QR code, we can successfully and accurately carve the QR code effect we want as long as we pay attention to the following matters! As we all know, the laser marking machine makes bar codes with clear two-dimensional code effect, exquisite characters and easy recognition. And it can print two-dimensional code and barcode on various materials, including plastic, hardware, wood and paper. It does not fade and is not easy to damage. Non ordinary mimeograph effect can be compared. At present, it has been widely used in equipment, materials, devices, spare parts and daily necessities in all walks of life. Laser marking machine makes barcode, two-dimensional code has become an essential practical technology in people’s production and life.
The laser marking machine makes two-dimensional barcode. In fact, sometimes we find that the two-dimensional barcode is very fresh, but it can’t be read by the scanning gun. What’s going on here?
Now, let’s help you popularize some knowledge about QR code barcode scanning:
For example, red can only be used as the background color of two-dimensional barcode, not as the bar color. Because the scanning gun emits red light, the red light shining on the red code will produce a strong reflection, similar to shining on the white code. However, the requirement of barcode two-dimensional code recognition is that the reflection of space should be strong, while the reflection of code should be weak. Therefore, red with strong reflection of red light is only suitable for short color (background color), not for code color. The barcode QR code is very strict in terms of color, and not all colors can be used to print codes. The colors that can be short include white, yellow, orange and red. The colors that can be short include black, blue, dark green and dark brown. Other colors are not allowed.
After knowing this, we should try our best to produce two-dimensional codes and barcodes in the laser marking machine according to this requirement. Sometimes we can solve this problem by means of shading. These require us to constantly use our brains to find ways to improve our practical operation level.
