Higher viscosity fluids have larger particles and more pigment, enabling a wider colour gamut to be printed, as well as higher opacity of colours in a single pass proving extremely useful for delivering impact on many labels and direct-to-shape packaging printing applications.

High-build varnish embellishments can be achieved more easily, to add texture, visual impact, and functionality (such as ink that resists cracking on flexible surfaces) to labels and packaging. From braille and tactile warning triangles on labels, to the latest haptic effects for a high-end look and real shelf presence for rigid and flexible packaging, with Xaar’s Ultra High Viscosity Technology results can be achieved that have traditionally only been possible by using screen printing.

Energy can also be saved as UV fluids, which previously required heating to 45 degrees before jetting, can now be laid down at room temperature. Overall, less fluid is required as well, making the process even more sustainable.

Graham Tweedale, General Manager of Xaar’s printhead business unit, said; “We are already seeing how Ultra High Viscosity technology is opening up new possibilities for Xaar in a number of applications, particularly label and packaging.

“Whereas previously inkjet printheads have typically been only able to jet fluids of around 8 to 12 cP, our technologies enable printers to jet much higher viscosities, achieving a wider colour gamut and unparalleled opacity, and can be used to print an extensive range of special effects.

Ultra High Viscosity Technology is available across many of Xaar’s printheads including the Xaar Nitrox, the 50x series, and Xaar 2002.
