Daler-Rowney FW Artists’ Ink is an acrylic based pigmented water resistant ink giving a high degree of light fastness. Can be substantially diluted to achieve subtle tones, very similar to watercolour. Such washes will dry to a water resistant film and successive layers can then be made. Works well through airbrushes, technical pens (except metallic colours), dip pens, ruling pens and brushes. Made in England.
