Speedball : Screen Printing : Acrylic Extender Base : 946ml (32oz)

Speedball Screen Printing Acrylic Extender Base is a versatile medium designed to increase the transparency of Speedball Acrylic Screen Printing Inks. It can be mixed in any ratio with the inks, allowing artists and printmakers to create subtle tonal variations, layered effects, or achieve more delicate colour blends without altering the ink’s texture or handling.

Ideal for general screen printing applications, this extender base works seamlessly with Speedball’s richly pigmented, permanent acrylic inks, which are suitable for paper, cardboard and wood. The inks dry to a matt, water-resistant finish and are available in standard, process, metallic, fluorescent, and glow-in-the-dark colours. Non-toxic and water-washable, they offer a safe and reliable option for both professional and classroom use.
