MUTOH achieves UL GREENGUARD Gold Certification for US11 ink

25 April 2019

MUTOH, a leading manufacturer of wide-format inkjet printers, announced that their original LED-UV ink or UL’s US11 ink is now the UL GREENGUARD Gold certified. 

UL’s GREENGUARD Certification Program is a widely used standard for design professionals, consumers and others to find low emitting interior products that promote better indoor air quality. Products that achieve GREENGUARD and GREENGUARD Gold Certification have demonstrated low chemical emissions during normal use. Some products, such as printing inks, are used in a wide variety of applications.

The GREENGUARD test method includes standardised room exposure models for both an office and classroom environment developed by the California Department of Public Health. The stringency of these models is directly related to the surface area of product that will be used in the room. For products that may be used in many applications, UL considers all potential applications and awards certification for the highest surface area loading for which the products meet the GREENGUARD and/or GREENGUARD Gold Certification criteria.
