Perfect for adding stunning, iridescent effects into prints, Speedball® Opaque Fabric Screen Printing Inks can be painted on with a brush or screen printed onto a range of textiles, paper and cardboard. These inks offer greater opacity without sacrificing any workability or softness of the fabric, and are ideal for use on dark fabrics. Speedball’s® Opaque Fabric Screen Printing Inks are washfast (when properly heat set), non-flammable and contain no solvents or offensive odor.
