42T, a FuturePrint Partner, has developed a groundbreaking technology that could revolutionize the digital printing of aqueous inks, particularly in the packaging industry. This innovation addresses the growing need for more sustainable practices in the printing and coating sector. As manufacturers increasingly transition to water-based (aqueous) inks, traditional drying methods like hot air and infrared are proving inadequate. These conventional techniques are not only energy-intensive but also unsuitable for heat-sensitive materials such as plastic films. This limitation results in reduced flexibility, higher operational costs, and a larger environmental footprint.
To overcome these challenges, 42T has turned its attention to radio frequency (RF) dielectric drying. This technology promises faster, more targeted, and significantly more energy-efficient drying compared to traditional methods. RF drying could provide a substantial upgrade in drying technology for the industry, enabling manufacturers to adopt aqueous inks more effectively and sustainably.
Dr. Peter Brown, Chief Commercial Officer at 42T, highlights the importance of this development: “The shift to aqueous inks is commendable, but the challenge of drying these inks efficiently is often overlooked. RF drying has the potential to deliver a transformative step-change in drying technology for this industry, and I am excited to see its future progress.”
Recently, FuturePrint visited 42T’s laboratory to witness a demonstration of this innovative technology, led by Rowan Beale, Head of Hardware Development at 42T. The demonstration showcased the practical application and benefits of RF dielectric drying, offering a glimpse into its potential to enhance the printing and packaging industry.

This development represents a significant step forward in making digital printing more sustainable, efficient, and versatile, particularly in the packaging sector. With its potential to reduce energy consumption and improve production efficiency, RF dielectric drying could indeed be a game-changer for the industry.
