FW Acrylic Ink is an acrylic-based, water-resistant pigmented ink in a range of 60 colors. All of the inks have either a 3 or 4 star rating for permanence with the exception of the fluorescent colors.
Such a high degree of lightfastness over a range of fully intermixable colors makes them ideal for use by artists in the production of pictures for permanent display.
Colors can be substantially diluted to achieve the most subtle of tones, very similar in character to watercolor. These washes will dry to a water-resistant film and successive layers of color can be laid over in a consistent manner. FW inks can also be used with airbrushes and technical pens.
