Ink jet printing method, ink set, and printed matter

摘要

Provided is an ink jet printing method of discharging glitter ink, of which glitter pigment is dispersed in water, onto a non-ink-absorption or low-ink-absorption printing medium in an ink jet method. The ink jet printing method includes: a foundation layer formation process of forming a foundation layer by providing resin ink, of which a resin component is dispersed or dissolved in a dispersion medium, onto at least a portion of the printing medium on which the glitter ink is intended to be discharged; and a glitter ink printing process of discharging the glitter ink onto the foundation layer.

1. An ink jet printing method of printing aqueous glitter ink, in which glitter pigment is dispersed, onto a non-ink-absorption or low-ink-absorption printing medium or a printing medium of which an arithmetic average roughness Ra is 20 μm or more, the ink jet printing method comprising:
forming a foundation layer by providing foundation ink, which includes a resin component, onto at least a portion of the printing medium on which the aqueous glitter ink is intended to be recorded; printing the aqueous glitter ink onto the foundation layer; and permeating water in the aqueous glitter ink into the foundation layer so that the glitter pigment is smoothly arranged on the foundation layer to control glossiness of the foundation layer such that a 60-degree glossy of the foundation layer is 90 or more; wherein the resin component is at least one material selected from the group of styrene-acrylic acid copolymer and polyurethane; the forming of the foundation layer includes drying the foundation layer at a drying temperature that is 30° C. or more and 120° C. or less; and an arithmetic average roughness Ra of the foundation layer is 20 μm or less.
