Daler Rowney FW Artists' Ink is an acrylic based pigmented, water resistant ink in a range of 38 colours, giving a high degree of light fastness. Colours 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. This ink works well in airbrushes, technical pens (except metallic colours), dip pens, ruling pens and brushes. #fwartistsink #dalerrowney #abacuscreativeresources
