Liquid ejection control device, liquid ejection system, and control method

Abstract

In a liquid ejection control device, an operation unit includes a momentum dial for inputting a momentum instructing value related to momentum of a pulsed liquid jet ejected from a liquid ejection device, and a repetitive frequency dial for inputting a repetitive frequency instructing value related to the number of times ejection of the pulsed liquid occurs per unit time. In addition, a controller includes a voltage magnitude setting section that sets voltage magnitude of the drive voltage waveform such that the momentum becomes the momentum instructing value, based on a rising index value related to rising of the drive voltage waveform and the repetitive frequency instructing value.
