Mutoh obtains Greenguard Gold Certification for its US-11 series flexible UV LED inks

May 07, 2019

Japan based wide format printer manufacturer MUTOH Industries Ltd., represented by Mutoh Europe nv for the EMEA business area, today announced that it has obtained Greenguard Gold Certification for its US-11 series flexible UV LED inks.

With this certification, Mutoh US-11 series inks meet the UL 2818-2013 Gold Standard for chemical emissions for building materials, finishes and furnishings. The certification provides assurance that the US-11 series inks meet some of the world’s most stringent and comprehensive standards for low emissions of volatile organic compounds (VOCs) into indoor air. As such, prints made with US-11 inks are suited for indoor applications including office, classroom and healthcare environments.

Greenguard Gold Certification is a voluntary certification issued by UL Environment with worldwide recognition. As opposed to Greenguard, it offers stricter certification criteria and considers safety factors to account for sensitive individuals such as children and elderly. It requires lower total VOC emissions for indoor environments and helps print buyers to identify and integrate certified, healthier and more sustainable products into their buildings.

“This new Greenguard Gold certification demonstrates Mutoh’s continuous commitment in offering digital printers and inks which are safe and environmentally responsible and which contribute to healthier indoor environments, says Kenji Yasuhara, Mutoh Europe’s Managing Director. “The certification will offer Mutoh printer owners using US-11 series inks full peace of mind and a competitive advantage being able to offer a certified solution for decorative wall applications”, says Yasuhara.
