Abstract
A method of printing an image on a substrate, where a solid border is printed on the substrate, the solid border corresponding to the perimeter of the image. A dead zone, in which no media is applied, is defined adjacent to and interior of the solid border, and a gray pattern is printed adjacent to and interior of the dead zone. A printer according to the present invention is for printing an image on a substrate, and has a data processing means and printer elements. The data processing means has a solid border controller for adjusting the width of a solid border corresponding to the perimeter of the image, and for producing a solid border parameter. Also included in the data processing means is a dead zone controller for adjusting the width of a dead zone adjacent to and interior of the solid border, and for producing a dead zone parameter. The data processing means also includes a gray pattern controller for adjusting the shape and density of a gray pattern printed adjacent to and interior of the dead zone, and for producing a gray pattern parameter. The printer elements are responsive to the data processing means, and receive the solid border parameter, the dead zone parameter, a…
