Akua Intaglio Inks deliver brilliant colors, intense blacks and unmatched working properties. They dry through absorption-they will not dry on the printmaking plate-and clean up easily with soap and water. These inks are ideal for Intaglio/Etching, Monotype, Gel Printing, and Collagraph printmaking and can be used with Akua Modifiers. They are water-based and non-toxic.
