Abstract
A surface of a workpiece has a smooth region, and a stepped region including a step. A three-dimensional object printing method includes first print operation of ejecting liquid from a head onto the smooth region, and second print operation, antecedent to or subsequent to the first print operation, of ejecting liquid from the head onto the stepped region. The amount of change in an angle of ejection, which is angle formed by a first normal line and a second normal line, during execution of the second print operation is larger than the amount of change in the angle of ejection during execution of the first print operation. The first normal line is a line normal to the ejection face. The second normal line is a line normal to the surface of the workpiece at a point of intersection with the first normal line.
