Abstract
A printer head with overlapping nozzles. A plurality of head chips are formed in an array pattern on the printer head wherein a plurality of nozzles are associated with each head chip. Nozzles associated with one head chip and nozzles associated with an adjacent head chip partly overlap to form an overlapped area. When an ink-ejecting mechanism drives across a print object, the nozzles of the one head chip and the nozzles of the adjacent head chip respectively eject inks which are mixed in the overlapped area to reduce dot density differences on the print object.
