ABSTRACT:
A method provides an optimized set of waveforms for driving a printhead in greyscale printing wherein the waveforms include a pulse train of N pulses, wherein N is an integer, each pulse having a length LN, a time P(N-1)(N)existing between two adjacent pulses. The method includes: optimising a cost function that compares at least one ink ejection parameter such as drop velocity, difference in drop velocity, driving voltage, split velocity, number of split drops or drop placement error, with a printing speed parameter such as printing speed, the length LNof each pulse or the time P(N-1)(N)between two adjacent pulses.
