1. A printing method implementing a piece of equipment comprising an energy-delivering exciter orientable to produce a punctiform interaction with at least one ink that possibly contains non-uniformities and that is deposited on a printing medium having a transparent interaction area, in order to cause a transfer of a targeted portion of said ink to a receiver, wherein the method comprises generating a wetting film at least partially covering said transparent interaction area, followed by depositing said ink on the surface of said wetting film.
