ABSTRACT:
A method and apparatus for inkjet printing by means of a plurality of inkjet nozzles arranged in at least one row and having spaced, parallel nozzle axes for emitting liquid ink drops towards the substrate, and multi-level charging and deflecting plates controlled to deflect individual drops to selected locations on the substrate with respect to the respective nozzle axis according to the pattern to be printed. The multi-level charging and deflecting plates are controlled to cover, for each nozzle, a line section which includes two non-contiguous deposit zones to receive ink drops from the respective nozzle, separated by a non-deposit zone not to receive ink drops from the respective nozzle. Various arrangements are described, wherein the nozzles are arranged in a single row or two staggered rows; the printing is effected in a single pass or two passes; the nozzle line sections are overlapping, contiguous or spaced from each other; and the deposit zone of one nozzle overlaps at least a part of the deposit zone of another nozzle.
