Abstract: An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. A process for variable data lithographic printing includes applying a dampening fluid to an imaging member surface; forming a latent image by evaporating the dampening fluid from selective locations on the imaging member surface to form hydrophobic non-image areas and hydrophilic image areas; developing the latent image by applying an ink composition comprising an ink component to the hydrophilic image areas, the ink composition comprising orange/violet/green (OVG) ink formulations resulting in a 7-color ink set meeting the extended color gamut requirements for digital advanced lithographic imaging printing.

Abstract: This disclosure is directed to functionalized carbon black material that may be particularly usable for as a filler material to a number of beneficial uses, particularly in image forming devices. 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 dispersion in fluorinated polymers, and fine dispersion in solvent. The disclosed surface passivated carbon black particles are particularly usable for improving operational characteristics of fluorosilicone-based reimageable surface layers of imaging members employed in variable data digital lithographic image forming devices.
