Abstract
There is provided a droplet deposition apparatus comprising: control circuitry configured to generate a common drive waveform; storage to store data, wherein the storage comprises a buffer to store scheduled image data relating to one or more pixels; a droplet deposition head having one or more actuator elements configured to be driven in response to drive pulses derived from the common drive waveform; and wherein the common drive waveform comprises a plurality of pixel periods comprising a firing phase and a non-firing phase, each firing phase comprising a firing pulse and each non-firing phase comprising a non-firing pulse, wherein the characteristics of each non-firing pulse are defined in response to the data in storage, and wherein, the firing pulse of a first pixel period is applied as a drive pulse to an actuator element based on the scheduled image data relating to a first pixel, and wherein the non-firing pulse of the first pixel period is applied as a drive pulse to the actuator element based on past image data and/or the stored scheduled image data.
