Patent ID: 7703909

Claim:
A six-pen ink set for ink-jet printing, comprising: a magenta ink-jet ink having a colorant load capable of providing a visible absorbance at peak maxima between about 0.01 and about 0.06 at a 1:10,000 dilution of colorant to water; a gray ink-jet ink having a colorant load capable of providing a visible absorbance at peak maxima between about 0.001 and about 0.05 at a 1:10,000 dilution of colorant to water; a medium cyan ink-jet ink having a colorant load capable of providing a visible absorbance at peak maxima between about 0.01 and about 0.10 at a 1:10,000 dilution of colorant to water; a black ink-jet ink having a colorant load capable of providing a visible absorbance at peak maxima between about 0.02 and about 0.75 at a 1:10,000 dilution of colorant to water; a second magenta ink-jet ink having a colorant load capable of providing a visible absorbance at peak maxima between about 0.02 and about 0.5 at 1:10,000 dilution of colorant to water; and a yellow ink-jet ink.
