Blending Medium — For use with Akua-Kolor or Akua Intaglio inks. Use blending medium to thin the ink for brushwork, wash effects or use as a resist for viscosity monotype. This clear liquid cleans up with water.

Extender — Use Extender to thin Akua-Kolor only (not recommended for Akua Intaglio inks). Medium amber in color, Extender has a liquid consistency and cleans up easily with water.

Oil Converter — Adds depth and thickens Akua Intaglio ink. Clear/white in color with a very stiff consistency, it cleans up with liquid dish soap followed by water.

Retarder — Retarder serves two purposes: it acts as a release agent for printing on dry paper and retards Akua-Kolor from drying on the monotype plate, therefore extending the working time. Use with Akua-Kolor only (not necessary with Akua Intaglio inks). This clear liquid retarder cleans up easily with water.

Tack Thickener — This modifier thickens and deepens Akua-Kolor colors. It can be used for creating denser Akua-Kolor roll-ups onto monotype plates. It has a thick consistency, medium amber color, and cleans up with soapy water.

Transparent Base — Transparent Base is Akua Intaglio ink without the pigment. It can be used with both Akua-Kolor and Akua Intaglio inks. Adding Akua-Kolor to Transparent Base will thicken Akua-Kolor and create new intaglio or relief colors. When added to Intaglio ink, this base will increase the ink's transparency. It has a thick consistency and light amber color, and cleans up with liquid dish soap followed by water.
