Introducing a new ink technology AQUAFUZE from Fujifi lm is a new inkjet ink technology, which combines water-based and UV-curable ink technology. It opens up new possibilities for wide format inkjet printing applications AQUAFUZE inkjet ink technology is Fujifi lm Group’s proprietary technology for stable water dispersion of photopolymers. Fujifi lm Group has applied its original synthesis technology for highly functional materials and particle dispersion technology. Based on this dispersion, Fujifi lm Group has developed a new UV-curable aqueous ink by combining the formulation technologies of both water-based and UV-curable inks.
The UV-curable aqueous ink is suitable for indoor signage and wallpaper applications, meeting the growing needs of the wide format market. It provides safe and odourless ink during printing, as well as offering a high level of rub resistance and compatibility with a variety of print substrates. The UV-curable aqueous ink featuring AQUAFUZE inkjet ink technology is expected to become the new standard in the wide format market, expanding the scope of customers’ business in the future.
Industrial inkjet inks are classifi ed into three types: water-based, solvent, and UV-curable. These inks are selected by users based on their characteristics and printing applications. In wide format inkjet printing, water-based inks that cure with heat, and UV-curable inks that cure with light radiation are mainly used. As the wide format fi eld continues to grow, printing applications and substrates are becoming more diverse. As a result, users now require inks that offer high durability for printed materials and stretchability for ink fi lms. These features are necessary for bending and processing of products. In addition, users also prioritise the safety of the ink, including preventing solvent volatilisation and minimising odours generated during printing. This is an important factor when choosing an ink. The main features of UV-curable aqueous ink developed by AQUAFUZE inkjet ink technology: • The use of photopolymer dispersion reduces clogging of the inkjet printhead due to ink drying and achieves stable ink ejection.
• The ink adheres to a wide variety of substrates without pre-coat primers and optimisers. • Printed image thickness is reduced, and the ink surface becomes more even, resulting in light refl ection and creating a glossy appearance.
• UV curing eliminates the need for a top coat on the printed substrate. • Ink odour is reduced, enhancing user safety. • The new UV-curable aqueous ink will be launched in autumn 2024.

for digital-container printing Marabu UK’s increasingly popular range of digital printing inks has
recently been enhanced still further with the introduction of an innovative high-performance ink for digital-container printing.
Ultra Jet DUV-CP enables higher quality print images – at twice the printing speed – and with an overall lower print consumption. With Ultra Jet DUV-CP individual effects can be achieved on glass, plastic and metal containers with ink fi lm thickness of up to 3mm. A higher pigment density ensures perfect edge defi nition – even for fi ne details – high opacity and an overall wider colour gamut.
Ultra Jet DUV-CP enables higher quality print images
In addition to the lower ink consumption the product eliminates the time-consuming intermediate step of ‘pinning’ the digital ink to the substrate. Other recent exciting news from Marabu has been the award of Greenguard Gold – a certifi cation which confi rms strict requirements on quality, safety and sustainability for digital printing inks.
To achieve Greenguard Gold Marabu’s inks were tested on a wide range of chemicals and as a result they comply with the exacting requirements for chemical emissions of volatile organic compounds into interior air.
Passing this test means they can be used in particularly sensitive environments such as hospitals and schools.
