    摘要: A system and method are provided for producing variable pearlescent image elements or portions on image receiving media substrates using a variable digital data offset lithographic architecture which provides for varying lithographic images between cycles of a marking device. Pearlescent inks are provided with a solid particle pearlescent pigment components in a proportion of at least 10% by weight suspended in solution in an ink composition. Pearlescent inks are provided with a solid particle pearlescent pigment components having particle sizes in excess of ten microns suspended in solution in the ink composition. The disclosed systems and methods provide for variable pearlescent image elements or portions to be formed on an image receiving medium substrate separate from, or in combination with, other ink image elements or portions applied using other inks in a single device, and/or in a single pass of the image receiving media substrates through an image forming system.
