Abstract
An inkjet printing system includes an array of transducers to eject ink, the array including the transducers divided into interspersed sets. A controller controls a firing sequence of the array of transducers. One set of transducers is fired, and after a delay, another set of transducers is fired and then, after further delays, each set is fired in turn. The delays are selected based on known response characteristics of the array of transducers to minimize the average crosstalk for all of the sets.
