The active energy ray-curable red ink has a higher printing density, higher light resistance, and an approximation to the process hue than the conventional red ink having light resistance similar to that of the process hue. Provision of printed materials. [Solution] When the active energy ray-curing red ink having light resistance is printed on an RI tester full roll with an ink deposit of 0.175 to 0.200 cc, the density value is 1.52 to 1. 57, and the L * a * b * value is in the range of L *: 50 to 55, a *: 75 to 83, b *: −14 to −20. Printing method of line curable ink. [Selection figure] None |
