Winsor & Newton Drawing Inks are formulated from a series of soluble dyes in a superior shellac solution. These inks can be applied with brush, dip pen or airbrush and are widely used by designers, calligraphers and artists as well as illustrators. These drawing inks are fast drying, water resistant and transparent, allowing the overlaying of different colours for attractive optical colour mixtures. All water colour brushes can also be used with inks to create interesting texture and lines.
