Poly Plus white has been developed for use on 100% polyester garments. The problem with printing on 100% polyester is the dye in the garment releases around the same temperature that the plastisol cures causing dye migration. Our poly plus white works great with 100% polyester and also with problematic 50/50 blends. Our poly plus white ink has a high opacity, high bleed resistance, and the lowest price in the industry that makes it second to none.
