    In printing and color gamut analysis, CMYK are frequently discussed, but there is also a "fifth" color to consider, which is the substrate that is being printed upon. Some variables that are impacted by the substrate used include how the ink received and volume of ink required to reach target print densities. Thus, the choice of substrate can greatly affect the quality of the final printed product. It was determined that the final color gamut of the coated paper was dependent on both the whiteness of the coating pigments used and the structuring of those pigments. Small changes in the optical and structural properties of the coating pigments and the coating pigment size impacted the final color gamut. Coated paper whiteness was achieved by using pigments with improved raw, natural whiteness. Light scattering was improved by changing the pigment particle size and morphology, moving the coating structure pore volume toward the optimum for optical performance.
