Abstract: The present invention provides a method and apparatus for printing an image to an open end surface of bound document during the printing process. The method and apparatus slices an open edge image to the outer edges of the obverse surface of a select number of pages. The image is crept incrementally increasingly inward through a registered window with each consecutive page sheet. The amount of each increment is equivalent to the height of the open edge image divided by the number of page sheets the image will occupy on the open surface of the bound document.
