Abstract: A printed image data generation method includes: a data acquisition step of acquiring data indicating a three-dimensional shape model imitating a printing target object and data indicating a two-dimensional image for decorating a surface of the printing target object; and a printed image data generation step of calculating a position of a surface of the three-dimensional shape model on which ink ejected from a nozzle is to land, determining a pixel of the two-dimensional image corresponding to the position of the surface, and generating data of a printed image to be printed on the printing target object based on information of the pixel.

Abstract: A printing unit includes a plurality of ink jet parts and an X-axis linear motion mechanism that moves each of the plurality of ink jet parts in the same main scanning direction. The X-axis linear motion mechanism moves the ink jet part involved in printing the workpiece among the plurality of ink jet parts so as to face the surface of the workpiece and moves the remaining ink jet part on the one X-axis linear motion mechanism so as to retreat from the surface of the workpiece. As a result, a printing apparatus that is capable of printing accurately onto the workpiece having a three-dimensional curved surface is provided.
