The FW Artists’ Ink is an acrylic-based, pigmented, water-resistant ink. This ink is ideal for use by artists in the production of artwork for permanent display. Equally, however, it can also be substantially diluted to achieve the most subtle of tones, very similar in character to watercolor. Such washes will dry to a water-resistant film on virtually all surfaces and successive layers of color can be laid over. This FW Artists’ Ink works well through airbrushes and technical pens.
