FW Artists` Ink is an acrylic based pigmented water resistant ink in a wide range of tantalising colours, all of which have either a 3 or 4 star rating. Such a degree of lightfastness over such a range of fully intermixable colours makes them ideal to be used by artists in the production of pictures for permanent display. ideal to be used with dip pen, technical pen, brush, & airbrush. It`s water resistant & non-clogging. The inks, being pigment based, are strong & rugged. Strong bold applications of FW can be made, where colour strength, expression & fluidity are required. Equally, however, colours can be substantially diluted to achieve the most subtle of tones, very similar in character to watercolour. Such washes will dry to a water resistant film & successive layers of colour can be laid over in highly predictable manner.
