This device comprises a control panel (23) in which said representation is digitally stored, a platen (9) of flat shape designed to accept a support, such as a sheet of paper, an airbrush printing tool (7) designed for airbrush printing (7), comprising a hopper and a reservoir (21) designed to take ash and ink that are to be mixed by the hopper, the airbrush printing tool (7) being designed to be able to create airbrush prints using the mixture contained in the reservoir and supplied by the hopper, the airbrush printing tool (7) furthermore being mounted with the ability to move relative to the platen (9) along three orthogonal axes and being numerically controlled into its positions along the three axes by the control panel (23) so as to allow the digital representation to be airbrush printed onto the support.
