Formulated to be directly printed onto medium to dark colored, cotton/polyester blends & 100% polyester garments. In most cases you can use a print/flash/print technique. These inks provide great coverage and have a creamy body unlike most bleed resistant inks. Low mesh count and good ink deposit is key.
