Matsui International is a PVC free water-based ink producer, and advocate of environmentally friendly practices, offering a variety of water-based inks and specialty products for a broad range of products. We have an array of inks that are all water based and with no ‘co-solvents,’ the majority of which have been OekoTex 100 Grade 1 certified, the highest grade, approved for skin contact garments like swimwear, underwear, and infant clothing. Our advance in water-based inks are making screen printing quicker, easier, and longer lasting; debunking outdated reputations that water based inks aren’t opaque, or lack in color fastness.
