Systems and methods for delivering aqueous pearlescent digital printing ink compositions using digital offset lithographic printing techniques

A method for forming variable pearlescent image elements or portions on image receiving media substrates, comprising:

• applying at least first image elements or portions on image receiving media substrates using at least one first ink from at least one first ink source for inked image formation on the image receiving media substrates in a single image forming device, the at least one first ink being a conventional imaging ink;
• at least partially curing the at least first image elements or portions on the image receiving media substrates;
• applying variable second image elements or portions on the image receiving media substrates with at least one variable data lithography device, the second image elements or portions being variable pearlescent image elements or portions and the at least one variable data lithography device including:
• an imaging member with a reimageable surface supporting digital data reimaging for lithographic image transfer to an image receiving medium substrate;
• a wetting solution source that deposits a layer of wetting solution on the reimageable surface;
• an optical patterning subsystem that patterns a latent image according to received digital data in the layer of wetting solution through selective evaporation of the layer of wetting solution;
• a second ink source that supplies the pearlescent ink to the reimageable surface to produce a pearlescent inked image from the patterned latent image for transfer of the pearlescent image elements or portions to the image receiving media substrates;
• and
• final curing the pearlescent image elements or portions and the other ink image elements or portions as image elements on the image receiving media substrates by a curing device to produce an output document that includes variable pearlescent image elements or portions in different parts of the output document.
