Abstract
A printing method employs a piece of equipment comprising an energy-delivering exciter that is orientable to produce a punctiform interaction with at least one ink that possibly contains non-uniformities and that is deposited on a printing medium including a transparent interaction area, in order to cause the transfer of a targeted portion of the ink to a receiver. The method includes a step of generating a wetting film at least partially covering the transparent interaction area, followed by a step of depositing the ink on the surface of the wetting film and transferring steps.
