System 3 Screen Printing Medium slows down the drying of acrylic colour on the screen and reduces the risk of screen blocking, making it easier to wash out. The medium can be thinned with water. System 3 Acrylic Colours retain great density of colour even after mixing with medium and very substantial covering power can be achieved on paper, card and board without undue cockling.

Also available in sizes 1lt and 5lt
