Akua-Intaglio ink is the first water-based etching ink. It is an asset to any printmaking artist who wants to work with materials that are less harmful to themselves and the (work) environment. The ink has a high percentage of pigment and is made with gum-based binders. This allows sharp prints to be made on moistened paper. The paper can be moistened immediately after printing for the next print run. It is even possible to print on non-moistened paper, which can be advantageous for color printing. Wiping-off is much easier than with traditional oil-based intaglio inks.
