    Abstract: The disclosed systems and methods provide an ink-based digital printing system for printing high quality images on a wide latitude of image receiving media. The disclosed systems and methods employ a UV curable base (transfix) layer deposited on an intermediate image transfer member that is then at least partially cured prior to an aqueous ink being deposited on the base layer to form a digital image thereon. Once the images are formed on the base layer, a drying device is optionally used to reduce a water content of the aqueous ink images on the base layer prior to transfer of the images to an image receiving media substrate. At transfer, the images and at least a portion of the base layer are transferred to the image receiving media substrate, the images being sandwiched between the portion of the base layer and the image receiving media substrate.

    Abstract: This disclosure is directed to formulations for inks and methods for achieving those formulations for use in an emerging class of variable data digital lithographic image forming devices. Specific sub-system requirements that are unique to the emerging architecture caused an exploration of formula boundaries that, through experimentation, were determined to substantially reduce particle sizes for the color pigments enabling a higher latitude for ink image thickness. Experimentally-derived behavior in reducing particle size and adjusting rheological properties results when a inks are processed using a 3-roll mill with cooling employed. Inks demonstrated a preferably reduced preferred particle size distribution enabling a higher latitude for ink image thickness down to about 0.5 microns. Improved rheological profiles allow the inks to have higher zero-shear or static viscosity to be less runny and to allow more consistent flow into and through ink loaders and Anilox systems to a reimageable surface of an imaging member.
