Flint Group Narrow Web introduces UV LED Flexo Ink System for shrink sleeves
The Flint Group (Luxembourg) has globally launched EkoCure XS – a UV LED ink series with good adhesion and post shrink performance on shrink substrates, that is also dual-cure, and provides consistent cure at the highest printing speeds.
“We knew from interviews with clients specialising in the short run shrink sleeve market that they want a UV dual-curable ink with better adhesion and increased curing speed to boost productivity and reduce yield losses,” states Kelly Kolliopoulos, global marketing director for Flint Group Narrow Web. “Our experience in LED and conventional mercury curable ink system technology, combined with our understanding of the shrink market, enabled our R&D team to develop this best-in-class system.” She concludes, “EkoCure XS combines the latest ink chemistry including novel binders that provide perfect cure and sufficient flexibility of the cured ink allowing the adhesion to remain fool-proof – especially after post shrink processing is completed. The full range of pantone shades and opaque white are available.”
“Our scientists have developed a unique combination of photo-initiators and binders allowing the ink to cross link from top to bottom and therefore cure fully when exposed to the UV wavelengths from either Mercury or LED lamps,” explains Dr Paulo Vieira, director of research and development, Narrow Web NA. “In depth tests comparing EkoCure XS with existing UV curable inks on the market show that EkoCure XS exhibits the best adhesion performance at the highest printing speeds when run using standard 355 W/inch mercury lamps. This is in addition to having the best performance when compared to other LED curable products.”
