ABSTRACT:
To provide a digital printing system that can satisfactorily reproduce yellow, magenta, and cyan colors, respectively, and can excellently reproduce specific skin tones and have significantly improved sensory image quality, a digital printing system reproduces 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; a magenta (M) color having a* and b* values of +50 to +65 and −30 to 0, respectively, at a green density of 1.0; and a cyan (C) color having a* and b* values of −45 to −15 and −40 to −5, respectively, at a red density of 1.0 and produces a print having L*, a*, and b* values of +58 to +78, +20 to +30, and +25 to +32, respectively, from digital image data with RGB values of 239, 167, and 127, respectively.
