Abstract:
1. A droplet dispensing control method comprising: detecting an amount of positional deviation in a rotation direction in a stage plane between a stage mounting a substrate on which an imprint material from an ink jet head lands and a template that is pressed into the imprint material on the substrate, as a template positional deviation amount; detecting an amount of positional deviation in a rotation direction in the stage plane between a movement direction of the stage and a nozzle array direction of a plurality of nozzles provided on the ink jet head, as a nozzle positional deviation amount; calculating a stage movement direction correction value configured to correct the movement direction of the stage and an ejection timing correction value configured to correct the ejection timing of the imprint material ejected from the respective nozzles, as a correction value for eliminating the positional deviation of a landing position of the imprint material occurring due to the template positional deviation amount and the nozzle positional deviation amount; and controlling the movement direction of the stage using the stage movement direction correction value and controlling the ejection timing of the imprint material ejected from the respective nozzles using the ejection timing correction value.
