Abstract
An inkjet printhead comprises an array of parallel channels separated one from the next by side walls transversely displaceable in response to an actuating signal. Pattern dependent crosstalk is avoided by applying to a channel selected for actuation a signal held at a given non-zero level for a period of length greater than that the length of the period at which the velocity of droplets ejected from said channel is at its maximum and at which the velocity of a droplet ejected from said selected channel is substantially independent of whether or not channels in the vicinity of said selected channel are similarly actuated to effect droplet ejection simultaneously with droplet ejection from the selected channel.
