Paper Abstract

A novel method for resolution enhancement of Electro Photographic (EP) printers is presented. The proposed method is applicable for laser printers that have a partial-pixel exposure capability such as Pulse Width Modulation (PWM). By coupling partial exposure with anti-aliasing rendering, the proposed technology enables practically continuous addressability, namely, placement resolution. Using this technology we can show significant print quality improvement, such as the ability to render lines with arbitrary width and location. This would allow printing smooth line art at any angle with a relatively coarse pixel grid. The proposed method will thus provide better print quality compared to post process type resolution enhancement alternatives used today. The method has been tested theoretically using a Liquid EP (LEP) model, and experimentally confirmed.
