In the field of trademark printing, traditional mercury lamp curing technology is gradually being phased out due to problems such as high energy consumption and mercury pollution. Nowadays, the combination of trademark machines and LED UV curing lamps is driving the industry to transform towards high efficiency and environmental protection. Taking self-adhesive label printing as an example, an enterprise has achieved a double breakthrough in production efficiency and environmental protection performance by installing a customized LED UV curing system on a rotary trademark machine.

LED UV curing technology has significant advantages: its light source life can reach 20,000-30,000 hours, which is more than 10 times that of traditional mercury lamps. Moreover, it can start instantly without preheating, avoiding energy waste. Data shows that the power consumption of this technology is only 30% of that of mercury lamps. A single device can reduce carbon dioxide emissions by 1.4 tons per year, equivalent to the annual emissions of a car. In addition, LED UV curing adopts cold light source design, and the surface temperature rise is less than 5°C, effectively protecting heat-sensitive materials and avoiding ozone pollution, which complies with the EU RoHS standard.

A new type of UV-LED curing lamp developed by a certain technology company in Shanghai has increased light energy utilization by 40% and curing speed by 30% through optimizing the concentrating structure and has been successfully applied to the cosmetics label printing production line. Another case shows that after a packaging enterprise transformed a traditional trademark machine, the defective rate of printed products decreased by 60%, the unit energy consumption cost was reduced by 12%, and annual electricity savings exceeded 100,000 yuan. These practices prove that LED UV curing technology not only realizes the low-carbonization of the printing process but also improves product quality through precise control, creating significant economic and environmental benefits for enterprises.

With the tightening of environmental protection policies and the upgrading of market demand, the deep integration of trademark machines and LED UV curing technology has become an industry trend. In the future, this technology will further promote the printing industry chain to develop in a green and intelligent direction and help achieve the “dual carbon” goal.
