Abstract
A dry toner image is embedded in a thermoplastic layer on a receiving sheet by pressing a ferrotyping web against the image in the presence of sufficient heat to soften the layer. Preferably, the layer is preheated and the web and image are pressed together by a pair of hard rollers to a pressure in excess of 100 pounds per square inch. A curl preventing layer opposite thermoplastic layer does not offset on a backing roller because it has a melting point above the temperature of the process.
