The severity of printer pollution directly affects whether users make purchases. In the external environment, with the strict requirements of environmental protection and the closure and punishment of high polluting enterprises, printing companies need a new type of environmentally friendly printing equipment to upgrade internally. Overall, printer pollution is not severe and can be analyzed from four aspects.

　　1、 Printer noise pollution

　　During the printing process, if the noise level of the original type of printer is less than 60 decibels, it not only meets the requirements for residential use, but also meets the decibel requirements for industrial type noise. Avoiding the physical hazards of hearing and vision caused by long-term exposure to high noise pollution by operators.

　　2、 Printer light pollution

　　During the printing process, the printer emits light waves through LED curing lamps, which contain ultraviolet light. If stared at for a long time, it can cause discomfort and dryness in the eyes. So in the design, the position of the light is very low, avoiding the diffusion of high position light everywhere, and also requiring operators to wear protective goggles during work. In practice, since the equipment is set up and automatically printed, there is no need for technicians to stare at it for a long time.

　　3、 Printer odor pollution

　　This is mainly reflected in ink. Although ink has very low pollution compared to traditional printing dyes and has passed environmental protection testing, it does not mean that it has no chemical properties. In practice, the printed pattern can evaporate its odor after being left for 24 hours. The odor generated during production is also small.

　　4、 Printer pollution

　　The piezoelectric inkjet printing system ensures on-demand printing, unlike traditional printing that generates a large amount of waste and waste liquids that need to be discharged. The waste ink generated by a printer working for a month, not exceeding 1L, can be directly imported into the sewer and rinsed.
