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.
