<p>A flexographic printing apparatus for printing a moving web (22) is provided with a rotatable ink roller (12) , a roller support (16) that rotatably supports the ink rollers, an ink source (14) associated with the ink roller which provides ink for the ink roller (12), and a rotatable printing roller (18) associated with the ink roller. A semi-conductive printing plate (30) is disposed on the printing roller (18) that makes physical contact with the ink roller, so that ink is transferred from the ink roller to the printing plate as the ink roller and the printing roller rotate. The printing apparatus also has a rotatable backing roller (20) disposed adjacent the printing roller (18) so that the moving web (22) on which ink is to be applied passes between the backing roller and the printing plate as the backing roller and the printing roller rotate so that a printed image is applied to the web. The apparatus also has a charge applicator (26) that causes an electric charge to be applied to the semi-conductive printing plate (30). <IMAGE> <IMAGE></p> |
