摘要： A method of forming a xerographic image having at least one portion with a gloss different from a gloss of another portion of the xerographic image includes xerographically forming a toner image on a surface of a substrate and forming a finish over the toner image at the at least one portion, the finish being made of a differential gloss finish coating material that has a gloss different from that of the toner image. The differential gloss finish coating material is preferably an emulsion aggregation toner that is substantially free of pigments that adversely affect the transparency of the toner following fusing, the toner having gloss tunability through control of the amount of crosslinked portions included in the toner.
