The working process of the UV inkjet printer is to make a picture through the PS software, click the print output instruction to the UV inkjet printer, and then the machine will automatically print the pattern as required according to the instruction. The ink is water-based. During the printing process of the UV inkjet printer, the UV lamp next to the nozzle will illuminate the ink pattern on the object with the left and right printing of the nozzle car. The UV light has a temperature of about 60-80 degrees. After the ink is printed, the UV lamp has already dried the pattern.

1. Curing principle: UV inkjet printer react with the photosensitive curing agent in the UV ink through the ultraviolet wave emitted by the LED cold light source lamp, causing the pigment molecules in the UV ink to solidify on the surface of the material to achieve the drying of the ink. It is completely different from the previous printing equipment that requires baking, drying and other processes. This can reduce unnecessary equipment and personnel expenses while increasing production efficiency.
2. Printing principle: The UV inkjet printer uses piezoelectric inkjet printing technology, which does not directly contact the surface of the material, and relies on the internal voltage of the nozzle to eject the ink in the nozzle onto the surface of the substrate to achieve the purpose of printing pictures. Among them, the nozzle plays a key role. Generally, there are thousands of nozzle holes on a small nozzle. It is difficult to see these nozzle holes with the naked eye, and the nozzle can finely control the ink output of the nozzle holes.
3. Positioning principle: UV inkjet printer can accurately control the purpose of printing patterns on different materials, different volumes, different heights, and various shapes. In the positioning of the X-axis, the raster decoder is mainly used to direct the horizontal printing of the equipment; in the Y-axis, the drive of the servo motor is mainly used to control the length of the printing material; the positioning of the height mainly depends on the machine head Lifting function. 
UV inkjet printer can be applied to common fields such as decoration and decoration industry; glass industry furniture sliding door industry; advertising industry; packaging industry; leather industry; textile industry; mobile phone digital industry; stationery industry; toy industry; handicraft industry. In addition, there are some undeveloped and unpopular industries.

1. Printing media: In the production process of UV printers, due to the failure of the nozzle and the adjustment of the media position, the print quality of the picture will be affected. The main reason is that the nozzle drips and leaks ink, or the nozzle is too close to the material medium, which causes the nozzle to generate friction on the surface of the medium and damage the image quality. The printed material must be laid flat, which will be a better equipment and suction device. Of course, another reason is that the printed material is too transparent or too thick. At this time, it is necessary to reload the printing material to ensure a smooth surface and to replace the opaque printing material.
2. Ink droplets phenomenon: UV printers occasionally have ink droplets during the printing process. This is usually due to the humidity of the air filter on the sub-ink cartridge, which leads to poor ventilation. This may also be due to the small hair and dust in the nozzle of the UV flatbed printer. When these dirt accumulates to a certain extent, the ink will drip out automatically. In order to solve this problem, we need to replace the air filter, and also need to clean the sprinkler head with a special cleaning fluid. We need to carefully check the two sides of the light box cloth to see if there is any excess burrs. If there is, we can simply use a lighter to deal with it.
3. Data transmission: Maybe you will encounter such a situation, the UV printer cannot print even if you press the start button, because the indicator light of the UV printer will keep flashing after transmitting the print data. This is also a common printing failure, and it is difficult for operators to deal with inexperienced personnel. It should be noted that if the UV flatbed printer terminates the printing operation improperly, even if the printing job is stopped, some residual print data will still be transmitted to the UV flatbed printer on the computer side, and these print data will still be retained in the memory. For UV flatbed printers, these data are invalid, so the printing work will not be realized, which will also cause the subsequent printing work to be unable to proceed normally.
4, it is necessary to do a good job of preventing the nozzle from drying out, and after printing, ensure that the nozzle is sealed. Otherwise, it will be exposed to the air for a long time. Ink is easy to condense and cause nozzle blockage.
