Abstract (en)
[origin: EP3069884A1] A drop-on-demand inkjet printing head comprising a nozzle assembly having at least two nozzles (111A, 111B), each nozzle (111A, 111B) being connected through a channel (112A, 112B) with a separate liquid reservoir (116A, 116B) and having at its outlet (113A, 113B) a drop generating and propelling device (161A, 161B) for forming on demand a primary drop (121A, 121B) of liquid at a nozzle outlet (113A, 113B), wherein the first nozzle (111A) is configured to discharge a first primary drop (121A) along a first path and the second nozzle (111B) is configured to discharge a second primary drop (121B) along a second path which is not aligned with the first path, characterized in that the printing head further comprises a set of electrodes (141, 142) for altering the path of flight of the second primary drop (121B) to a path being in line with the path of flight of the first primary drop (121A) before or at a connection point (132) to allow the first primary drop (121A) to combine with the second primary drop (121B) at the connection point (132) into a combined drop (122), wherein each of the first primary drops (121A) and second primary drops (121B) are output to a surface to be printed.
