Mutoh obtains Greenguard gold certification

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

This certification confirms that the Mutoh US-11 series inks meet the UL 2818-2013 Gold Standard for chemical emissions for building materials, finishes and furnishings and provides the 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 the 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.

The Mutoh US-11 C, M, Y, K, White and Varnish flexible UV LED inks were specifically developed for use with Mutoh’s extensive range of UV LED printers for roll-to-roll, hybrid and flatbed applications, including the ValueJet 1638UR, ValueJet 1638UH, ValueJet 426UF and ValueJet 626UF printers.

The inks are Nil percent VOC and non-HAP inks, meaning no special ventilation nor air purification is required in the working environment.

Available in 220 ml cassettes, 800 ml (CMYK, VA) and 500 ml (WH) packs and offering excellent adhesion, the inks enable printing on the widest range of media including heat sensitive, transparent and non-white substrates. They also allow multi-layer and spot varnish printing.
