Abstract
A method for printing input digital images using an inkjet printing system having a first and second drop ejector arrays for ejecting drops of a particular ink, wherein ink paths supplying drop ejector arrays have different length projections. The method comprising printing a first combined number of ink dots using the first and second drop ejector arrays during first and third time intervals where the printhead is accelerating and decelerating; and printing a second combined number of ink dots using the first and second drop ejector arrays during a second time interval where the printhead is moving at a substantially constant velocity, wherein the percentage of ink dots that are printed by the drop ejector array having a longer length projection is less than 40% of the corresponding combined number of ink dots in at least one of the first or third time intervals.
