Our LED UV printing technology used for posters, signs, banners, vinyl, window and floor clings, auto vinyl, decals, and retractable banner products, to name a few, are produced using GREENGUARD GOLD Certified inks. The UL GREENGUARD Gold Certification Standard includes health-based criteria for additional chemicals and requires lower total VOC emissions levels to ensure that products are acceptable for use in environments such as schools and healthcare facilities.
