Opacity control of unpainted pixels

Abstract

A method and a system to create either a white default background or any other selected default color without the need to coat the whole region or section of the medium upon which the object or image is to be printed on under the object with the desired media color. This is done by determining for each pixel within the region if there is colorant to be applied, and if not, to apply the default colorant. This could be achieved in more than one approach.
