Mastering the Airbrush

Airbrush

Add subtle hints of colour to your sketches

or ink drawings 

The airbrush sprays a liquid colour much like an aerosol, but with far more precision.

The air pressure, the distance between the airbrush and the support and the fluidity of the paint determine the type of colour jet. The airbrush is based on a system of air bursts that, through a pipe, release or block the jet of paint. The first version of the airbrush was created in 1893 by the American watercolourist Charles L. Burdick. He then founded the Fountain Brush Company in London, dedicated to the manufacturer of the first airbrushes. The airbrush is handled like a pen, between the thumb and the middle finger and the trigger is pulled with the forefinger. The air flux is released by pushing down the trigger, and the paint is spouted by pulling the trigger.

Airbrush maintenance

The airbrush must be cleaned after each use with the most delicate part being the nozzle. It must stay perfectly clean so that the needle can be changed without problems, so eliminate any dried or glued paint residue as soon as possible. The trigger must also be well-maintained and preserved.

We distinguish two categories of airbrushes: single action or dual action.

Using a single action airbrush is easier, as the colour and air are released when the trigger is depressed. These designs are also cheaper.

For Dual action the air is activated by exerting a pressure on the trigger and the colour flow is handled by pulling the trigger back, allowing the user to control the volumn of airflow and the concentration of paint flow independently. This allows for a wider variety of artistic effects.
