  • Patent number: 5916667
    Abstract: With proper control of the surface energy of the press ink and the surface tension of the ink jet ink, an article which has a press ink coverage of greater than 30% screen can be successfully imaged with ink jet ink to provide substantially uniform coverage of ink jet ink in the imaged areas. The ink jet ink to be imaged over the press ink must be low enough in surface tension to enable it to wet the surface of the printed article and to be retained on the surface of the article. The ink jet ink can be compatibilized with the press ink either by adjusting one or both of the surface tensions of the ink jet ink and the press ink and/or through the use of a compatibilizing liquid which provides a compatible interface between the ink jet ink and the press ink.
