Abstract

The invention provides an ink jet method and an ink jet apparatus, which can improve the color reproduction range and the bleeding balance. The ink jet method includes a step of ejecting a first composition from an ink jet head, the first composition being a radiation-curable composition having a hue angle of -50-degree to -5-degree; a step of ejecting a second composition from an ink jet head, the second composition being a radiation-curable composition having a hue angle of 5-degree to 50-degree; and an exposure step of curing the ejected first composition and the ejected second compositionby exposing the ejected first composition to radiation within 1 second after landing of the ejected first composition and exposing the ejected second composition to radiation within 1 second after landing of the ejected second composition.

Description

technical field [0001] The present invention relates to an inkjet method and a recording device. Background technique [0002] The inkjet recording method can record high-definition images with a relatively simple device, and has been rapidly developed in various aspects. For example, Patent Document 1 discloses a polymer dispersant, a monomer, a diketopyrrolopyrrole pigment, and a pigment derivative represented by a specific general formula that are excellent in pigment dispersibility, ejection stability, and storage stability. Active energy ray curable inkjet ink. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2006-348200 [0004] However, according to the ink composition described in Patent Document 1, it was found that there is room for improvement in the balance between the range of color reproduction and bleeding. Contents of the invention [0005] The inventors of the present invention conducted intensive studies to solve the above-mentioned problems. ...
