Abstract

A starting image is printed on a flat generally circular substrate by first converting Cartesian coordinates of the pixels of the starting image into polar coordinates to create a first intermediate image in polar form. Then, from the first intermediate image, a second intermediate image is made in Cartesian form with the radial position of each pixel of the first image on the Y-axis and the angular position on the X-axis. A size of each pixel of the second intermediate image is adjusted--stretched or compressed--in accordance with its position on the Y-axis and from the adjusted-size pixels a third intermediate image is formed. The pixels of the third intermediate image are brightened to form a fourth intermediate image that is overlain with a gray-scale raster. A raster analysis is done on the fourth image to create a print image that itself is applied to the substrate.
