ABSTRACT:
Disclosed is a method for preliminarily printing a blank for a tapered draw-formed body, which comprises transforming digital rectangular coordinates to annular coordinates so that the height of the rectangular coordinates is made to correspond to the height of a tapered plane on which the printed image is to be manifested and the change of the area of the tapered plane by a minute change of the height of the tapered plane is made equal to the change of the area of the annular plane. In this method, excessive flattening of the image in the lateral direction is prevented when the resulting preliminarily printed blank is draw-formed, and an image having a beautiful appearance and a high commercial value can be reproduced.
