Abstract
A method for applying a liquid material in a specific application amount includes an initial parameter setting step of specifying, as a total pulse number, the number of times both ejection pulse signals and pause pulse signals are sent, specifying the number of ejection pulse signals in the total pulse number, which is needed to achieve the specific application amount, and specifying the remainder of the total pulse number as the pause pulse signals; a correction amount calculation step of measuring, per preset correction period, an ejection amount from the nozzle at the timing of the correction period, and calculating a correction amount for the ejection amount; and an ejection amount correction step of adjusting the number of ejection pulse signals and the number of pause pulse signals on the basis of the correction amount calculated in the correction amount calculation step.
