Abstract
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.
