There are 45 colours in the range of Daler Rowney FW Acrylic Ink. All come in a 29.5ml bottle with dropper.
The pigments used in the conventional colours for the FW range are ground to a very small particle size (smaller than a grain of soot) so will pass through technical pens to a size of 0.18mm and can be used through fine-line nozzles when airbrushing. They can, of course be used with brushes or dipper pens.
FW inks have grown in reputation over the years as a consequence of their high intensity and clarity of colour The unrivalled lightfastness for the range of fully intermixable colours makes them ideal for use by artists in the production of pictures for permanent display.
The inks are strong and rugged so bold artwork can be achieved, where colour strength, expression and fluidity are required. Equally the colours can be substantially diluted to achieve subtlety of tones, very similar in character to watercolour. Such washes will dry to a water resistant film and successive washes can be overlaid in a highly predictable manner.
