Fog development for digital offset printing applications

Ink-based digital printing systems useful for ink printing include a photoreceptor layer configured to receive a layer of liquid immersion fluid. The liquid immersion fluid includes dampening fluid, dispersed gas particles, and charge directors that impart charge to the solid particles. The photoreceptor surface is charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged liquid immersion fluid adheres to portions of the photoreceptor surface according to the electrostatic latent image to form a fountain solution image. The fluid portion of the fountain solution image can be partially transferred to an imaging member and/or transfer member to form a dampening fluid image, either or both of which may be electrically biased. The dampening fluid image is inked on the transfer member, and the resulting ink image transferred to a print substrate.

IMAGE FORMATION WITH ELECTROSTATIC FIXATION

A device includes a media supply, a first portion, and a second portion. The media supply is to supply a media along a travel path and to which a ground element is to be electrically connected. The first portion along the travel path is to receive droplets of ink particles within a dielectric carrier fluid on the media to form at least a portion of an image on the media. The second portion is downstream along the travel path from the first portion and includes a charge generation portion to emit airborne charges to charge the ink particles to move, via attraction relative to the grounded media, through the received carrier fluid toward the media to become electrostatically fixed on the media.
