Provided are an inkjet printing method and an ink set, in which forward and reverse warp inks are printed in an arrangement that reduces warp. The forward warp ink is the ink in which a warp when cured and shrunk by irradiation of light is a forward warp in which a portion on a side where light is irradiated by a light irradiation device is large in the degree of curing and shrinkage as compared with a portion on an opposite side. The reverse warp ink is the ink in which a warp when cured and shrunk by irradiation of light is a reverse warp in which a portion on a side opposite to a side where light is irradiated by the light irradiation device is large in the degree of curing and shrinkage as compared with a portion on the side where light is irradiated.

The present disclosure prevents a visible pattern corresponding to the pattern of a mask from being noticeable and enables more appropriate printing. A printing apparatusperforming printing by an inkjet scheme includes: an inkjet head; and a controller, configured to control the operation of a main scan driverand a sub scan driverto perform a main scanning operation multiple times on each position on a medium. In the main scanning operation, for at least part of ejection positions serving as ejection targets of ink droplets in the main scanning operation, the controllercauses the inkjet headto eject an ink droplet in accordance with a mask for selecting part of the at least part of ejection positions. In the main scanning operation at one time, the controllercauses the inkjet headto eject an ink droplet in accordance with a preset first mask. In the main scanning operation at another time different from the one time, the controllercauses the inkjet headto eject an ink droplet in accordance with a second mask for selecting an ejection position in a pattern different from the first mask.

The problem addressed by the present invention lies in obtaining printed material having higher brightness using an ultraviolet-curing metallic ink. In order to solve this problem, the printing method includes: an ink ejection process, in which an ultraviolet curing type metallic ink including metal particles is ejected on a recording medium, and the recording medium is swelled by the metallic ink, soaked with the metallic ink, or dissolved by the metallic ink; a leveling process, in which the metallic ink on the recording medium is leveled; a temporary curing process, in which ultraviolet rays are irradiated to the metallic ink on the recording medium to cure in such a degree that the metallic ink is not completely cured; and a main curing process, in which ultraviolet rays are irradiated to the metallic ink on the recording medium for curing after the temporary curing process.

Printing method

A printing apparatus, including: an ink jet head for ejecting ink droplets of an ultraviolet curing type ink toward a medium; a temporary curing ultraviolet light source; an irradiation setting storage section which stores ultraviolet irradiation settings of ultraviolet rays from the temporary curing ultraviolet light source to the medium; and a curing completion ultraviolet light source being for completing curing of the dots of the ink, is provided. The ink jet head performs a printing by a multi-pass method. The ultraviolet irradiation settings are set so that, regarding temperature of the region where the ink jet head ejects ink droplets in each main scanning operation in the multi-pass method, an increasing range of temperature compared with temperature at a timing of the last main scanning operation is suppressed within a temperature rising range which dot gains of the dots of the ink are substantially the same as each other.
