Process for applying protective overcoat on printed media |
摘要 |
A process of forming an overcoat on a printed image to provide improved stability comprising: a) applying an image layer on a substrate using a liquid ink to form an imaged element; b) either charging the imaged element to a given polarity or applying a voltage across the surface of the element which is attracted to a conductive surface behind the element; c) applying colorless, charged particles to the element which causes them to be electrostatically attracted to the surface of the image layer; and d) heat-fusing the particles to obtain a protective overcoat over the entire surface of the image layer.
