When the two sub heads are not overlapped, the printed pattern state is as shown in fig. 10, and the two sub lines overlap at the extreme end (0).
In actual printing, it is often necessary to fill out the places where the corresponding values are dark in overlapping colors among 2 groups of sub-nozzles through a software overlapping eclosion technology, in the preset printing pattern shown in fig. 10, the diagonal line is printed by G1, the straight line is printed by G2, and the physical arrangement has the situation that the spray holes of the 2 nozzles shown in the lower diagram have overlapping spray holes.
