The Charbonnel Aquawash Etching Ink has high pigmentation concentration. It can be used in all intaglio printing techniques such as engraving, dry-point, mezzotint,  etching and aquatint, as well as monotype and relief printing techniques such as linocut and wood prints. The binder is composed of several oil emulsions. Its adhesive quality, its flexibility and its yellowing characteristics are identical to those of traditional oils. The only difference being that you can wash hands, materials and tools with water! Water-washable oil-based emulsion. Wash up with soap &water. High pigment concentration (comparable with standard inks). Extremely lightfast. All colours can be intermixed. Easy to wipe, same drying times as standard inks. Will not soften when dry.
