Abstract:
Provided are an inkjet ink set for corrugated cardboard, the inkjet ink set including inks of five colors, including a cyan ink, a magenta ink, a yellow ink, a black ink, and an α ink, in which in a case where images having a halftone dot area ratio of 100% are formed on a corrugated cardboard base material using the five color inks each separately, the hue angle h, the chroma saturation C*, and the lightness L* of the formed images in the CIE 1976 L*a*b* color space satisfy the relations of the following Formula 1 to the following Formula 3; and an image forming method. In Formula 1, h M , h α , and h Y  represent the respective hue angles h of the inks. In Formula 2, C* M , C* α , and C* Y  represent the respective chroma saturations C* of the inks. In Formula 3, L* M  and L* α  represent the respective lightness L* of the inks. h M <h α <h Y   Formula 1 C* M <C* α <C* Y   Formula 2 L* M <L* α   Formula 3

Claim (Index 1):
An inkjet ink set for corrugated cardboard, the inkjet ink set comprising inks of five colors with different color tones, including a cyan ink, a magenta ink, a yellow ink, a black ink, and an \u03b1 ink, and the content of water is 50% by mass or more with respect to the total mass of the ink,\n wherein in a case in which images having a halftone dot area ratio of 100% are formed on a corrugated cardboard base material using the five color inks each separately, the hue angle h, the chroma saturation C*, and the lightness L* of the formed images in the CIE 1976 L*a*b* color space satisfy the relations of the following Formula 1 to the following Formula 3:\n h M <h \u03b1 <h Y \u2003\u2003Formula 1 \n C* M <C* \u03b1 <C* Y \u2003\u2003Formula 2 \n L* M <L* \u03b1 \u2003\u2003Formula 3 \n \n in Formula 1, h M  represents the hue angle h of an image formed by the magenta ink; h \u03b1  represents the hue angle h of an image formed by the \u03b1 ink; and by represents the hue angle h of an image formed by the yellow ink, \n in Formula 2, C* M  represents the chroma saturation C* of an image formed by the magenta ink; C* \u03b1  represents the chroma saturation C* of an image formed by the \u03b1 ink; and C* Y  represents the chroma saturation C* of an image formed by the yellow ink, and \n in Formula 3, L* M  represents the lightness L* of an image formed by the magenta ink; and L* \u03b1  represents the lightness L* of an image formed by the \u03b1 ink.
