Sustainable Printing Practices in the UK: Flexographic Printing Leading the Way
The UK, recognized as the sixth largest producer of printing products globally, is well-positioned to drive sustainability in the printing industry. Significant strides have already been made toward achieving Net Zero, with the sector adopting eco-friendly practices and materials. Commercial printing in the UK now predominantly uses sustainable resources, with 90% of paper sourced from European forests that are expanding at a remarkable rate—equivalent to 1,500 football pitches every day.
Among the various sustainable printing methods, flexographic (flexo) printing stands out as a key player in reducing environmental impact. Flexo printing is not only cost-effective and efficient but also offers several advantages that enable businesses to demonstrate their commitment to environmental responsibility.
Efficient Use of Ink
Flexographic printing is highly sustainable due to its efficient use of ink. Unlike traditional printing methods, flexo applies a thin layer of ink, minimizing waste. This reduction in ink consumption leads to less material ending up in landfills, where residual liquids can seep into the soil and harm local ecosystems. This approach ensures a cleaner environment while maintaining high-quality print outputs.
Environmentally Friendly Water-Based Inks
A major benefit of flexo printing is its ability to utilize water-based inks, which are far more sustainable than solvent-based alternatives. Water-based inks emit fewer volatile organic compounds (VOCs), reducing air pollution and improving indoor air quality for employees. Additionally, they are easier to dispose of, further contributing to environmental conservation. This makes them an ideal choice for businesses aiming to reduce their ecological footprint.
UV Inks for Quicker Drying
Flexographic printing also supports the use of ultraviolet (UV & LED UV) inks, which offer significant sustainability advantages. UV inks are cured instantly using ultraviolet light, eliminating the need for lengthy drying times. This not only boosts productivity but also reduces downtime and ink wastage. Furthermore, UV curing systems are more energy-efficient compared to traditional drying methods, helping to lower electricity consumption and carbon emissions.
Reduced Energy Consumption
Flexo printing has embraced advanced technologies like LED UV curing systems, which consume significantly less energy than traditional UV, hot air, or infrared drying methods. This reduction in energy usage not only lowers operational costs but also decreases the company’s environmental footprint and reliance on fossil fuel-generated electricity. By adopting these technologies, businesses can align with global sustainability goals while improving efficiency.
Minimising Waste
The integration of the latest inks and drying systems in flexographic printing allows for precise control over ink deposition and color management. This enhanced accuracy reduces errors and misprints, minimizing waste. As a result, businesses save on materials and resources, and fewer reprints are required, making production lines more cost-effective and sustainable.
Conclusion
Flexographic printing is a powerful tool for businesses aiming to enhance their sustainability efforts. By leveraging efficient ink usage, water-based and UV inks, advanced drying technologies, and waste reduction practices, flexo printing offers a pathway to greener operations. As the UK continues to lead in sustainable printing practices, adopting flexo printing can help businesses reduce their environmental impact while maintaining high standards of quality and efficiency. This approach not only supports the global push towards Net Zero but also positions companies as responsible stewards of the environment.
