FW Ink is a premium acrylic-based, pigmented, water resistant ink with a high degree of lightfastness and intermixability. FW Ink can be used straight out of the dropper, or 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. FW inks can be applied using traditional brushes, but also work well through airbrushes, technical pens, and paint markers making them ideal for producing technical illustrations and finely worked drawings. The expressive fluidity of acrylic inks is suitable for use by fine artists, illustrators, graphic designers, calligraphers, decorative artists and hobbyists. Set contains 1 each Crimson, Process Yellow, Process Cyan and 1 FW Mixed Media Marker. Colors may vary. ACMI Certified, Conforms to ASTM D-4236. This package contains three 29.5ml acrylic ink in assorted colors. Imported.
