Abstract
A method for reducing instability of a nozzle meniscus of a droplet deposition apparatus. The method includes the steps of receiving first and second data blocks for respective first and second line pixels, receiving a data set of forbidden pixel periods, determining a first jitter delay value based on the forbidden pixel periods, generating first and second print data based on the first and second data blocks, the first print data defining a first holding period and one or more drive pulses and the second print data defining one or more drive pulses; wherein the first and second print data generate first and second actuating element signals that cause an actuating element to eject at least one droplet from a nozzle, wherein the first jitter delay value adjusts a first pixel period, defined by the drive pulses, to fall outside of the forbidden pixel periods to reduce nozzle meniscus instability.
