Toppan Leefung Packaging & Printing (Dongguan) Co.,Ltd. stands as a premier high-end book printing enterprise specializing in premium publication design and production. Faced with escalating global environmental regulations and client demands for low-carbon supply chains, the company sought technological innovation to achieve “Quality Enhancement, Efficiency Gains, and Consumption Reduction” targets while aligning with China’s “Dual Carbon”  strategic goals.

After understanding the needs of customers, our technical team identified the following two problems through data analysis and equipment evaluation:

1. The content of VOC (volatile organic compounds) produced by ink & Drying Rate
   • Traditional mercury lamp curing systems consumed excessive energy while generating ozone pollution
   • Traditional inks exceeded VOC thresholds, failing to meet evolving environmental standards
   • Printing speeds were constrained, impacting order fulfillment timelines
2. Air Compression System Inefficiencies
   • Multiple standalone blowers/vacuum machines makes the energy loss is as high as 40%
   • Fluctuating pressure levels caused frequent production line stoppages
   • Escalating maintenance costs and excessive noise pollution (exceeding decibel standards)
   • Heat dissipation from equipment increased cooling energy losses

1. UV-LED Smart Curing System Upgrade
   • Deployed UV-LED curing technology on Komori GLX-840RP 8-color presses
   • Achievements:✓ 2.5% VOC reduction | ✓ 30% energy savings | ✓ Instant-start zero ozone emissions
     ✓ 20% faster printing speeds | ✓ 15% saving on ink consumption
2. Central Permanent Magnet Variable Frequency Air Compression System
   • Replaced energy-inefficient equipment with a “Smart Control System and Permanent Magnet Motors.”
   • Innovative Integrations:✓ Reduced production line cooling losses | ✓ Anti-rust dehumidification via refrigerated dryers | ✓
     Pressure stabilization through air storage tanks
     ✓ 25% variable frequency energy savings | ✓ 12dB noise reduction

• Project received endorsements from Hong Kong Environmental Protection Department (EPD) and the Department of Industry and Information Technology of Guangdong Province, securing HK$550,000 matching funds under the Cleaner Production Partnership Programme (CP3).
• The technical team maintains real-time tracking of environmental policy updates from relevant government authorities, ensuring clients receive the most accurate and timely information and strategic support.
