How to use 6090 uv printer to print QR code? Now customers who do advertising printing and processing will add a QR code of their own company to the advertisement to achieve a better promotion effect. But we all know that the two-dimensional code records the data symbol information with a specific geometric figure in black and white patterns distributed on a plane (two-dimensional direction) according to a certain rule. If the printing quality is unqualified, it will often cause product batches Therefore, printing quality is one of the most concerned topics for QR code printing companies.

So, what are the things that need special attention in the process of 6090 uv printer printing QR code? Micolorprint will tell you below.

1. Pay attention to the distance between the printing material and the nozzle

The distance between the material and the nozzle is usually about 2mm, but sometimes due to the curvature of the printed material, it is easy to cause the distance between the printed matter and the nozzle to change during the printing process.

2. Parameter adjustment when material changes

For different printing production tasks, the substrates will also be changed accordingly. When the material of the substrates produced in the first and last two productions is quite different, the metal trademark 6090 uv printer should be tested before mass production or judged based on experience how to adjust technical parameters such as printing resolution and nozzle temperature to meet large-scale printing tasks.

3. Eliminate lack of space behind

The space behind the two-dimensional code refers to the space on the right side of the last black bar of the two-dimensional code. Its main function is to prevent other color blocks from interfering with the scanning of the two-dimensional code. Usually in the design and plate making, many operators often only pay attention to the black bars, and take up the space behind the QR code at will when the layout position is not enough. The QR code is scrapped.

4. Avoid the wrong combination of blank colors

The current national standard only lists the standard requirements to be met by the color combination of the bar space, without specifying which combinations can be used and which cannot be used. In actual production, for the combination that is more difficult to grasp, we can only do proofing honestly, and only after testing and no problem can we carry out mass production.

In addition, other frequently encountered problems in QR code printing include wrong position, low printing quality, improper selection of mobile phone case materials, etc., which require special attention from operators.
