An ink jet print head 10 includes an array 12 (Fig.1) of nozzles 14 (Fig.1) arranged along an axis 16. The array has a first portion 22 in which the nozzles are spaced apart along the array axis by a first pitch, and a second portion 24 in which the nozzles are spaced apart by a different second pitch. The array may have a third portion 20 (Fig.1) between the first and second portions with a third pitch different from the first and second pitches. An assembly 30 (Fig.2) may include two or more of the print heads 10, with the second portion 24 of one head overlapping with the first portion 22 of the other head. The assembly may be operated by determining a best aligned pair of nozzles (72,83,Fig.5A), disabling the nozzles (73-75,84,85) extending beyond each member of the pair, and disabling one of the pair to prevent double printing of a single dot row, before printing therewith. The assembly ensures a seamless swath of printing. |
