Speedball Supergraphic Black Ink is the flagship colour in the Speedball Professional Relief Ink range. Developed in consultation with the printmaker and tutor Bill Fick, this is a rich, velvety black which holds detail well and will not clog up a block halfway through an edition. Like all colours in the range, this ink is a lightfast and fully archival oil-based printmaking ink which can be washed up with just soap and water.

Speedball Professional Relief Inks are designed for all types of relief printing, especially linocut and woodcut. Because this ink can be thinned with water, it is preferable to print onto dry paper.

This is an 8oz (236.5ml) tin of Supergraphic Black (PBK7, Speedball Lightfastness rating I). It is suitable for mixing with any of the Speedball Professional Relief Ink colours. To increase the transparency of this ink, add Speedball Professional Relief Transparent Base. The ink can be stiffened with talc or magnesium carbonate, and thinned with water.
