Abstract (en)
A procedure to obtain a drawing on a surface of a element (7) comprises the steps of fixing a coat paint, that is also a good electrical isolator, (such as powder or liquid varnish), on the surface; deposing or extracting electrical. charges on or from the surface in points reproducing the drawing; treating the surface with at least a electrostatic paint having an electrical charge opposed or equal to the charges deposed on the surface, depending on negative or positive drawing is to be transferred, in order to make the drawing visible; fixing the drawing so obtained by final polymerization of the paint. A plant (25) comprises a coating section (26) for fixing the coat paint, a second section (27) for deposing electrical charges on or extracting electrical, a electrostatic painting section (28) for treating the surface with at least a electrostatic paint.
