Ink is a liquid coloring agent that is used for writing, hand lettering, printing, drawing and airbrush. Talens inks and Amsterdam Acrylic Ink can be thinned with water and are waterproof once dry. Due to the high quality lightfast pigments they contain they do not fade.
You can use it pure or diluted with water to achieve a watercolour effect. The range of possible drawing and painting techniques with ink is very wide. All inks can be combined with other materials: pastels, watercolour, gouache, Ecoline, etc.
The Talens inks are available in black. The Amsterdam Acrylic Ink assortment contains 56 colours.
