Abstract
An inkjet printing method includes directing a printhead of an inkjet printer towards a substrate to be printed, generating ink drops in the printhead of the inkjet printer, and directing the ink drops, after they have been discharged from the nozzle of the printhead, into a zone with a locally increased temperature in such a way that the volume of the drops is actively reduced during the phase of flight to the substrate.
Claims14
An inkjet printing method, comprising:
- directing a printhead of an inkjet printer towards a substrate to be printed;
- generating ink drops in the printhead of the inkjet printer and discharging the ink drops from a nozzle of the printhead;
- and then
- directing the ink drops into a zone with a locally increased temperature so as to actively reduce a volume of the ink drops during a phase of flight to the substrate.
1 more element
An assembly comprising:
- an inkjet printhead having a nozzle;
- and
- at least one filament configured to have an electrical current applied thereto, or a light source between the nozzle of the inkjet printhead and a substrate to be printed, configured to generate a zone with a locally increased temperature and heating of ink leaving the printhead nozzle.
An attachment for a printhead of an inkjet printer, comprising
- a heat shield having an opening,
- first and second plates arranged directly on the heat shield, the plates being directed towards a substrate and provided with electrical supply lines, the plates being separated from one another by an intermediate space, the intermediate space being arranged underneath an opening of the heat shield, and
- at least one filament configured to connect the plates to one another,
- wherein the electrical supply lines are configured to conduct current via the plates into the at least one filament so as to generate a zone with a locally increased temperature.
