The design of an inkjet drive waveform using machine learning

open access: yesScientific Reports, 2022
AbstractA drive waveform, which needs to be optimized with ink’s fluid properties, is critical to reliable inkjet printing. A generally adopted rule of thumb for its design is mostly dependent on time-consuming and repetitive manual manipulation of its parameters.
