Summary:

Most research has being focused on rather the development of inkjethead, and of process, than on the landing accuracy of the droplets on a target. Thus, this paper presents the modeling and experimental verification on the static landing accuracy and precision of the droplets from the magnetostrictive inkjet head. A simple model based on the angle deviation of a nozzle tip and on a distance to a substrate is considered, assuming that there is no ambient effect. Three experiments have planned and preformed. The first is to collect the initial data for the landing distribution of the droplets. The second is to collect the repeatability data of the stage used. Then, these data are used to rederive the model. The final is to verify the equation and to show the calibration results. The respective landing accuracy of the droplet after calibration on the x-axis and on y axis has improved about 98 and about 90. The respective landing precision of the droplet after calibration on the x-axis and on y axis has improved about 87 and about 77. It can be concluded that the presented procedure is promising to predict and to validate the static landing accuracy of the droplets.
