Abstract
An ink set includes a light magenta ink and a dark magenta ink. The light magenta ink includes an effective amount of a pigment having a red/green lambda cutoff ranging from about 585 nm to about 600 nm, and reflecting at least about 14% of blue light at a wavelength of about 470 nm when measured at a density at which the light magenta ink provides a maximum magenta chroma. The dark magenta ink includes an effective amount of a pigment having a red/green lambda cutoff greater than or equal to about 605 nm.
