摘要： Ink-based digital printing systems useful for ink printing include a rotatable charge-retentive reimageable surface layer configured to receive a layer of fountain solution. The fountain solution is carried to the charge retentive surface by a fog or mist including fountain solution aerosol particles, dispersed gas particles, and charge directors that impart charge to the fountain solution aerosol particles. The charge-retentive reimageable surface may be charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged fountain solution adheres to portions of the charge-retentive reimageable surface according to the electrostatic latent image to form a fountain solution image thereon. The fountain solution image can be partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate.

摘要： This disclosure is directed to a plate design for use in variable data digital lithographic image forming devices. The disclosed plate design incorporates surface passivated carbon black filler material particles in a fluorosilicone polymer. The disclosed functionalized carbon black material compositions include hydrophobic carbon black particles passivated with polymerized pentafluorostyrene. The disclosed surface passivated carbon black particles have a diameter in a range of 50 nanometers to 1 micron, and enable enhances dispersion in fluorinated polymers, and fine dispersion in solvent. The disclosed surface passivated carbon black particles are particularly usable for improving operational characteristics of fluorosilocone-based reimageable surface layers of imaging members employed in the variable data digital lithographic image forming devices.

摘要： Ink compositions comprising a carrier and an inorganic particulate additive are described. The ink composition comprises a liquid carrier and an inorganic particulate additive, wherein bleeding of the additive into a fount solution in offset printing is reduced. The inorganic particulate additive has a washout factor, representing the extent of bleeding in offset printing use, of less than about 0.70.
