Derivan Waterbase Block Ink 250ml Medium (Extender)

Derivan Block Ink Medium & Extender is a versatile medium that can be used in two ways to create relief prints. Add Derivan Block Ink Medium & Extender to Derivan Block Ink to extend the colour without diluting the structure of your paint.

Up to a 1:1 ratio the colour will be extended, after this the colour will start to become more transparent. Derivan Block Ink Medium & Extender can also be added to Matisse Structure Acrylic colours to create block printing ink. A ratio of 1:1 is recommended.
