  • Publication number: 20180074398
    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 a high viscosity thickening agent to raise the viscosity of the composition from about 1.05 to about 2 times higher while maintaining excellent transfer to a substrate at low temperatures.

  • Publication number: 20180072899
    Abstract: An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. The ink is formulated to incorporate a gellant into the ink set to help meet the requirement of two different viscosity or temperature pairs at two different stages of the ink delivery process. In lithography imaging a bulk ink is first transferred onto an anilox roll and then onto the imaging cylinder blanket. The first transfer from bulk ink to anilox roll requires the ink to have a low viscosity while the transfer from roll to imaging blanket requires a high viscosity. The addition of the gellant will increase the viscosity difference within the allowable temperature range thus increasing process latitude and robustness.

  • Patent number: 9822267
    Abstract: An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. The ink is formulated to incorporate polyester viscosity modifier to help meet the requirement of two different viscosity or temperature pairs at two different stages of the process. In digital offset printing a bulk ink is first transferred onto an anilox roll, and then from the anilox roll onto the imaging cylinder blanket. During the bulk ink to anilox roll the disclosed ink has a low viscosity while the transfer from roll to imaging blanket the ink has a higher viscosity. The addition of the polyester viscosity modifier increases the viscosity difference within the allowable temperature range, thus, increasing process latitude and robustness.

  • Patent number: 9782771
    Abstract: Provided is a method of patterning a substrate. The method includes depositing, in a first predetermined pattern, hydrophobic material on a first surface of a hydrophilic substrate. The method includes permeating the hydrophobic material through a thickness of the substrate. The method includes exposing the hydrophobic material to UV-light and sufficiently solidifying the permeated hydrophobic material. The sufficiently solidified hydrophobic material forms a liquid-impervious barrier that separates the substrate into at least one discrete region.

  • Patent number: 9745484
    Abstract: A white ink composition for ink-based digital printing includes a white pigment. The white pigment is titanium dioxide. A method for ink-based digital printing includes applying dampening fluid to an imaging member to form a dampening fluid layer, patterning the dampening fluid layer using a laser imaging system, applying a white ink composition to the imaging member surface having the patterned dampening fluid disposed thereon to form an ink image, partially curing the ink image, and transferring the partially cured ink image to a printable substrate.
