Abstract: A calibration method includes acquiring medium information; specifying a type of medium by collating medium information with structure data; executing a first simulation of ejecting liquid by changing at least one of physical property conditions at least once for a structure model corresponding to a specified type of the medium; ejecting the liquid onto the medium; acquiring permeation information of the liquid ejected to the medium; estimating a physical property condition of the liquid by collating the permeation information with results of the first simulation; executing a second simulation of ejecting the liquid by changing at least one of ejection conditions at least once based on the estimated physical property condition; and displaying a plurality of virtual print results, which are virtual print results when printing is performed on the medium based on each of the ejection conditions, based on results of the second simulation.

Abstract: A gear device includes an internal gear, an external gear having flexibility configured to partially mesh with the internal gear and rotate around a rotation axis relatively to the internal gear, and a wave generator configured to come into contact with an inner circumferential surface of the external gear and move a meshing position of the internal gear and the external gear in a circumferential direction around the rotation axis. The external gear includes a cylindrical section including a first end portion with which the wave generator is in contact and a second end portion adjacent to the first end portion along the rotation axis. An inner circumferential surface of the first end portion includes a polished surface. An inner circumferential surface of the second end portion includes a lathe-cut surface.
