Formulated for use with System3 Acrylic Colors, this screen printing medium is designed to combine with acrylic paint to produce economical, low-odor, water-based and solvent-free screen printing ink that is ideal for use in schools, studios and at home. It slows down on-screen drying of acrylic color, reducing the risk of screen blocking and making it easier to wash out. It can be thinned with water. When mixed with this medium, colors retain great density of color, and very substantial covering power can be achieved on paper, card and board without undue cockling. If printing on textiles, this medium should be mixed in roughly equal quantities with colors.
