hubergroup Print Solutions has expanded its UV offset portfolio with low-tack versions of its NewV ink range, aimed at addressing increasing variations in paper quality and higher printing speeds.
The new low-tack variants are available for the NewV pack premium, NewV set LED, NewV pack MGA and NewV poly MGA series.
According to the company, the new formulations are designed to reduce issues associated with printing on sensitive papers and uncoated board. Lisa-Marie Spring, product manager SF/UV at hubergroup, said: “The term tack refers to the stickiness of a printing ink. While high tack offers advantages such as improved ink transfer and dot gain, it can also cause so-called picking on sensitive papers or uncoated board, damage to the paper surface during the printing process. Low-tack inks are specifically designed to counteract this effect.”
hubergroup said the low-tack inks retain the same rheological properties as the standard NewV series while offering benefits for printers working with variable paper qualities. These include reduced paper tear-out, more uniform ink separation, minimised emulsion disruption and a lower risk of delamination on multi-layer substrates.
The company says the inks are intended to support process stability in applications where paper quality fluctuates or presses are running at high speeds.
Spring said: “With the new low-tack versions of our NewV series, we provide our customers with reliable solutions that support a smooth and efficient printing process in line with today’s requirements.”
The development follows what hubergroup says is growing demand for lower-tack ink systems in response to changing conditions in press rooms.
