Multi-density ink-jet ink set for ink-jet printing

摘要

A multi-density ink-jet ink set comprising two black ink compositions and at least three colour inks, wherein the first black ink composition has a lightness L* in the range of 35 to 65 as calculated from the spectral transmittance of a 1000-fold dilution of the first black ink composition, and the second black ink composition has an lightness L* value in the range of 70 to 100 as calculated from the spectral transmittance of a 1000-fold dilution of the second black ink composition. A method for ink-jet printing is also disclosed.
