Next generation UV LED curing inks for sheetfed offset

30 January 2014

Flint Group's new Ultraking Xcura LED system of low energy UV curing highly reactive inks and coatings utilises specially selected materials to match the narrow and targeted wavelength (395nm) that is typical for high power UV LED lamp output.

The 395nm targeted wavelength eliminates both ozone and heat generation, resulting in a safer working environment and ability to print heat-sensitive substrates. UV LED offers additional advantages over traditional UV such as instant on/off, significantly longer lamp life (20,000 hours against 2,000) and low maintenance.

Rodney Balmer, Flint's director of global research and product development, avers: "UV LED lamp technology utilises high power light that emits diode technology, which requires significantly less energy to operate than traditional UV. This results in as much as 40 per cent reduction in energy costs."

Ultraking Xcura LED products are claimed to have high colour strength, display excellent ink/water stability and require lower levels of energy to operate. They also comply with ISO 2846-1 and are suitable for printing to ISO 12647-1 standards.

The product range includes standard process inks, a base mixing scheme, metallic inks, overprint varnish and - soon - a low migration product.
