Causes of wire drawing in the process of printing products on UV printers

In the industry, problems such as poor printing colors and printing ink drawing are called printing effect deviations. What are the reasons? The following editor will briefly introduce to you what are the reasons for wire drawing in the process of printing products on UV printers.

1. The nozzle is slightly blocked. The print head is composed of hundreds or even thousands of tiny inkjet holes. If several or even dozens of small holes are blocked, the color is not complete, which will lead to wire drawing.

2. The spray hole is slightly blocked. The nozzle holes on the nozzles are only partially blocked, which leads to deviations in the position of the ejected ink and the printed pattern, and also leads to deviations in the colors, and the phenomenon of flying ink appears.

3. The ink is slightly precipitated. If the ink is not used for a long time and there is no ink stirring system in the ink cartridge, the ink cannot be mixed uniformly again, and the deposits will also be ejected in the above-mentioned two situations.

4. There is foreign matter on the surface of the nozzle. If the machine is left in a place where the air is polluted for too long, the surface of the nozzle is blocked by large particles of dust, and the wire drawing and the color are not bright.

The above is an introduction to the reasons for the wire drawing in the process of printing products on the UV printer. I hope it will be helpful to everyone. If you have any other questions or questions, please consult our online customer service.
