Fabric Screen Inks are water-based, non-toxic, and non-flammable. Suitable for T-shirts, tablecloths, and other textiles made of cotton, polyester blends, linen, rayon, and other synthetic fibers (NOT for use on nylon). Also works great on paper and cardboard! Ink can be screen printed or painted on with a brush. For best results, pre-wash fabric and always pre-test before production runs.Mix with Speedball Transparent Base for transparency and Speedball Retarder Base to slow the drying process. Inks must be properly heat set. After the ink dries, use a paper or cloth interface and apply heat using a household iron at medium to high setting for 3 to 5 minutes on each side. Fabric Screen Printing Inks are easy to clean with water but become wash-fast when properly heat-set.Available in Night Glo and new Fluorescent Colors in 8 oz. jars. Jars have an inner seal and contain no solvents or offensive smell. AP Non-Toxic conforms to ASTM D-4236.
