Designed for bold, lasting results on both light and dark fabrics, Speedball Fabric Screen Printing Inks deliver rich, opaque color on linen, cotton blends, polyester, rayon, and other synthetic fibers. These non-toxic, waterbased inks are water-soluble, intermixable, and dry to a smooth satin finish that becomes permanent when properly heat set. Ideal for screen printing or brush application, they work beautifully on t-shirts, canvas bags, shoes, and more, with colors that remain vibrant even on darker materials.
