Winsor & Newton Inks have been used by illustrators since their introduction in the 1890’s where the main requirement was brilliance of colour. Today they are formulated from a series of soluble dyes in a superior shellac solution. These inks can be applied with a brush, dip pen or airbrush and are widely used by designers calligraphers and artists as well as illustrators. All colours in the Winsor & Newton line of Drawing Inks are fully intermixable and they are easily diluted (with distilled water). Fast drying and water resistant they have excellent adhesion on most surfaces.
