Apparatus for printing images on a convex surface of an object includes an ink jet print head having a supply of ink and located in a printing position relative to the object, the ink jet print head including means for ejecting ink along a first axis which intersects the center of the convex surface at the printing position and holds the object. The apparatus rotates the object about a second and third axes which intersect at the center the convex surface during printing, and controls rotation and the ink jet print head to cause the ink jet print head to eject ink along the first axis onto different positions of the convex surface to form an image on the object.
