Printing continuous tone images on receivers having field-driven particles |
摘要 |
An electronic printing apparatus responsive to a digital image for providing continuous tone optical density pixels forming an output image on a receiver includes a receiver including field-driven particles in a matrix that can change optical density in response to an applied electric field, the field-driven particles being responsive to fields of different amplitude and duration to change the optical density of the pixels formed in the receiver; an array of electrodes associated with the receiver for selectively applying electric fields according to the digital image forming pixels across the receiver; and electronic control circuitry coupled to the array and responsive to the digital images for computing appropriate voltage waveforms having amplitudes and durations selected so that, when the voltage array forms are applied to the array, fields are produced by the array and applied to the receiver to provide continuous tone pixels having optical densities corresponding to pixels in the digital image.
