Easy to use, water wash-up etching inks, also very suitable for relief printing, in a range of beautiful dense colours. Very buttery and easy to wipe. Can be left uncovered in the jar without hardening or forming a skin. Prints well on dry or dampened papers. Although water-based, the inks are not water-soluble and cannot be reactivated by water even while the prints are wet. As they contain no dryers the ink drying time will be similiar to oil based inks. When cleaning up use a dry rag on all surfaces. Clean any remaining residue with warm soapy water and a rag. Solar plates are cleaned with vegetable oil.
