Abstract
The invention pertains to a method for transferring ink to a receiving material using an inkjet printer having an ink chamber (10) with a nozzle (8) and an electromechanical transducer (16) in cooperative connection with the ink chamber, comprising actuating the transducer to generate a pressure wave in the ink chamber to expel a volume of ink from the nozzle, the pressure wave being such that it induces splitting of the said volume in a first and second ink droplet (36,37), wherein the transducer is actuated such that the volume of ink that is forced to be expelled from the ink chamber experiences a supercritical acceleration in the direction of the receiving material, whereafter the transducer is actuated to retract the second droplet (36) into the ink chamber. The invention also pertains to a print head adjusted for applying the said method and a printer incorporating such a print head.
