Patent ID: 7312896

Claim:
A digital printing system, comprising: an image processing means for processing digital image data; and an image output means for producing a printed output using at least yellow (Y), magenta (M), and cyan (C) coloring materials, wherein the system is so configured as to reproduce: a yellow (Y) color having a* and b* values of −15 to 0 and +71 to +85, respectively, in the CIE 1976 (L*a*b*) color space at a blue density of 1.0 using the yellow (Y) coloring material alone; a magenta (M) color having a* and b* values of +50 to +65 and −30 to 0, respectively, in the CIE 1976 (L*a*b*) color space at a green density of 1.0 using the magenta (M) coloring material alone; a cyan (C) color having a* and b* values of −45 to −15 and −40 to −5, respectively, in the CIE 1976 (L*a*b*) color space at a red density of 1.0 using the cyan (C) coloring material alone; and wherein the system is so configured as to produce a printed output having L*, a*, and b* values of +58 to +78, +20 to +30, and +25 to +32, respectively, in the CIE 1976 (L*a*b*) color space from digital image data having red (R), green (G), and blue (B) values of 239, 167, and 127, respectively, in the RGB color space.
