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.
Claims26
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.
A printing medium for an ink in interaction with an orientable energy-delivering laser to produce a punctiform interaction, said medium comprising:
- a transparent interaction area surrounded by a border in order to form a cylindrical space;
- a plurality of channels opening into said border of said cylindrical space operably injecting a wetting fluid of said transparent interaction area;
- one or more suction channels opening into said border of said cylindrical space;
- and
- a wetting film being configured to be formed by vapor condensation, capillary wetting and electrowetting.
