Abstract
Uneven glossiness is effectively suppressed between areas where light inks are mainly used and areas where dark inks are mainly used. The gloss is raised in areas where dark cyan ink C is used. In other words, the application amount of second clear ink applied by after application printing is set to 32% at primary cyan (grid point 16) to equalize the gloss with areas where light cyan ink LC is used. Also, the application amount of first clear ink applied by common printing is set to 32% in a highlight portion (grid point 8) to equalize the gloss with the maximum gloss reached using dark cyan ink C. In so doing, it is possible to keep the gloss nearly constant over the entire range from white to cyan, or in other words, suppress uneven glossiness.
