An airbrush uses a process of nebulization which allows the air operated tool to spray various media including ink and dye, but most often paint onto surfaces. An airbrush works by passing a stream of compressed air through a venturi, which creates a local reduction in air pressure that allows paint to be pulled up from an interconnected reservoir at normal atmospheric pressure. The high velocity of the air atomizes the paint into very tiny droplets as it blows past a very fine paint-metering component. The paint is carried onto paper or other surface.
