<p>Provided are a method, apparatus, and program for jetting a liquid material, which make it possible to stabilize the droplet shape and the jetting state of the liquid material to be jetted and make it possible to improve jetting accuracy. In the liquid material jetting method, a measuring section which measures the liquid material, a jetting port connected to one end of the measuring section, and a plunger which moves by sliding on the inner wall of the measuring section are provided, a filling step, wherein the measuring section is filled with the liquid material by moving the plunger in the direction opposite to the jetting port, and a jetting step, wherein the plunger is moved toward the jetting port and stopped and the liquid material is flown and jetted from the jetting port, are performed. The method is characterized in that the speed of the plunger in the jetting step is controlled to be constant by providing a preliminary operation step wherein the plunger is moved without jetting the liquid material.</p> |
