Ci Flexographic Printing Press's Solvent-Free Printing Technology: A Dual Revolution in Environmental Protection And Efficiency

In the green and intelligent transformation of the global printing industry, Ci flexographic printing presses, with its solvent free printing technology, is reshaping the industry landscape with its dual advantages of environmental protection and efficiency. The technology not only breaks the environmental bottleneck of traditional printing process, but also achieves the qualitative leap of production efficiency through end-to-end optimization, becoming the core driving force in the field of high-end packaging printing.
I. Environmental Revolution: COMBATING POLLUTION AT SOURCE
In traditional printing process, the use of solvent-based inks is the main source of (volatile organic compounds) emissions. According to statistics, gravure printing can emit up to 28% volatile organic compounds, and while solvent-based flexographic printing is better than gravure printing, it still causes serious pollution. Ci flexographic printing presses' solvent-free printing technology solves this problem once and for all through three innovations:
Water-based ink substitution: Ci equipment use high concentrations of water-based ink with a VOC content of below 5%, well below the EU emission standard of 20mg/m3. In food packaging printing, for example, water-based inks can not only avoid contamination of food by solvent residues, but also be FDA certified to meet the stringent requirements of the high-end market.
Solvent-free plate-making process: Traditional flexible plate making relies on chemical solvents for cleaning, while the Ci equipment's pure water-washing plate,AWPTM-REVO, requires only tap water to wash, achieving a 90% recycling rate of the washing solution and a 90% reduction in waste. The process reduces VOC emissions per plate from 120g in traditional processes to less than 5g.
Solvent-free lamination technology: This device is used in conjunction with a a solvent-free laminator to completely eliminate VOC emissions during laminating by using hot melt adhesive instead of solvent type adhesive. For example, CPI Indonesia reduced VOC VOC during lamination from 1.2 kg to 0.05 kg per tonne of products following the introduction of the Bobst CI printing press and SX550 solvent free laminating equipment.
ii. Efficiency Revolution: Intelligent Upgrade of Whole Process
Ci flexographic printing presses' "solvent-free printing" technology is not only the upgrade of environment, but also the improvement of efficiency and quality through the transformation of production process by intelligent system:
High-Speed ​​Precision Printing: Precision printing Ci equipment with a central impression (CI) structure coupled with laser-engraved ceramic anilox rollers can be printed at a high speed of 300 meters per minute with a collimation accuracy ± 0.002mm. For example, in the printing of 0.2mm thick medical aluminum foil packaging, micron-scale precision avoids the risk of pharmaceutical contamination due to ink penetration, reducing scrap rate from 8% to 0.5% cent of traditional processes.
Intelligent Color Management: Ci devices use oneECG expansion color gamut technology to replace dotted ink with a fixed ink combinations (CMYK + orange/green/purple), reducing the time it takes to change color by 70%. Using the technology, a cosmetics company cut the lead time for single-use printing from 2 hours to 30 minutes, saving more than $2 million a year in ink costs.
Automated production closed-loop: Ci equipment integrates intelligent GPS intelligent mounting system, automatic tension control, online quality inspection station, and automates the entire process from loading to unwinding. Following the introduction of the system, CPI reduced its operator workforce from 12 to 4, improved production stability and reduced order lead times from 7 to 3 days.
III. Industry impact: Redefining green printing standards
Ci flexographic printing presses' "solvent-free printing" technology sparks chain reaction around the world:
Market Restructuring: Flexographic printing accounts for 80% per cent of the North American market, while the Asian market is growing at 15 per cent per annum. With its technological advantages, Ci equipment have helped chinese packaging companies wean themselves off gravure printing. Shenzhen Jiuxing Printing, for example, uses Ci equipment to replace pharmaceutical composite films with flexographic printing, driving the industry's shift to high end.
Standards-setting lead: The technical parameters of Ci equipment have become a core indicator for EU CE certification and US FDA certification. For example, its solvent-free lamination process has a peel strength of 4.5N/15mm, well above the industry average of 3.2N/15mm, providing a replicable green production model for global packaging companies.
Carbon Footprint Optimization: A joint study by Beijing Institute of Printing and Asahi Kasei shows that carbon devices reduce their carbon emissions by more than 30% over their entire life cycle compared to traditional gravure printing. Using Ci equipment, for example, could reduce carbon dioxide emissions by more than 500 tons per year, equivalent to the environmental benefit of planting 28,000 fir trees, according to a packaging company that produces 10,000 tons per year.
Epilogue: A vision for the future of green printing
The "solvent-free printing" technology, essentially precision manufacturing technology, environmental materials science and intelligent control systems deep integration. Practice shows that environmental protection is not a cost burden, but an opportunity for technological upgrading; efficiency is not a speed race, but the result of system optimization. When a printing press can define quality with micron-scale precision while protecting the environment and achieving zero pollution emissions, this is not only a new era of green printing, but also a vision for a sustainable manufacturing future.
