Abstract
A method for reducing rub-off from a substrate, such as paper, having a front side and a back side with a toner image on at least one side of the substrate by depositing at least one phase change composition on at least one image bearing side of the substrate as a plurality of dots, with the plurality of dots cumulatively covering an area of the image bearing side sufficient to reduce rub-off from the image bearing side, the dots being characterized by being one of colored dots, a combination of colored dots or a combination of colored and clear dots. The dots may also be applied only to the images rather than both the image-bearing and non-image-bearing surfaces of the substrate.
