ELECTRO-WETTING-ON-DIELECTRIC PRINTING

摘要

An electro-wetting-on-dielectric printing system includes a drum and an electrode array disposed on a surface of the drum, which is made up of individually addressable electrodes and an ink-phobic coating overlaying the electrodes. Electrically charging a portion of the electrodes allows ink to adhere to a portion of the ink-phobic coating in proximity to the charged electrodes. A method for electro-wetting-on-dielectric printing includes selectively charging individually addressable electrodes within an electrode array, and passing the electrode array through an ink bath, wherein ink adheres areas proximate to charged electrodes to form an image. The image is then transferred to the substrate.
