Firstly, check it whether the machine is damaged. Secondly: 1. It may be that the spray hole of the spray gun head is blocked, but it is not completely blocked, so the ink droplets ejected from the spray hole are not straight, so the spraying content becomes scattered. Just remove the nozzle and clean it. 2. In addition, the voltage of the nozzle is too high, the spraying force increases, and the spraying material is just very hard. Just reduce the voltage. 3. If the printing interval is too long, it will also cause scattered spots in the printing. In addition, the aging of the head of the inkjet printer will also produce dispersion points if it does not reach the maximum interval of inkjet printing. 4. Due to the unstable transportation of spray printing products, spray printing scattered points are generated. In addition, when other signals interfere with the signal of the inkjet printer, scattering points will also appear. 5. When using the inkjet printer, pay attenti

UV inkjet equipment UV inkjet printer refers to the piezoelectric inkjet printer that uses UV ink for inkjet printing. Its working principle is consistent with that of piezoelectric inkjet printer. Using the characteristic of piezoelectric crystal deformation, UV ink jet falls on the surface of moving articles to form dot matrix, so as to form words and patterns. UV inkjet printer and thermal foaming inkjet printer belong to high-resolution inkjet printer. In terms of inkjet printing quality, UV inkjet printer has better effect, high adhesion and higher definition. The cost of consumables is much lower than that of thermal foaming inkjet printer, which is suitable for large-scale mass production.

In our daily life, we will see that products have bar codes, serial numbers,logos and etc.which are printed with inkjet printer after the products produced, so any production-oriented enterprise must buy inkjet printer. But now there are many inkjet printer manufacturers on the market, how to choose

When choosing inkjet printer manufacturers, enterprises consider these aspects. Due to the rapid social and economic development, inkjet printer has become more and more common in our daily life. As we all know, the nozzle is one of the important components of the inkjet printer and one of the delicate components. The use of the nozzle focuses on maintenance and repair. The quality of maintenance and repair directly determines the service effect and service life of the nozzle, how to make your equipment bring greater profits and how to prolong the service life of the nozzle.

In today's society, QR code identification is a major black technology. It not only includes many of our current product identifications, but also has a wider and wider range, and the complexity of application has increased greatly, making identification an indispensable and important part in the production of various industries. Today, Danmajet will introduce the reasons for product identification and the choice of inkjet printer in different industries.

1. Firstly, the relevant production enterprises formulate or select coding rules and generate a certain number of QR codes to form a complete database system. 2. Send the generated database system to the relevant enterprises responsible for production and packaging. 3. Packaging enterprises receive the database for sorting and docking, send it to marking equipment such as inkjet printer, laser inkjet printer or high-resolution inkjet printer, and assign codes to products to realize what we often call "one object and one code". 4. Establish multi-level packaging relationships, such as bag box box and two-dimensional code association system, combined with the packaging that has been sprayed with code and the packaging that has not been sprayed with code, which can be customized according to customer needs to improve product quality control.
