Abstract
The invention provides an ink jet recording method and an ink jet recording apparatus, which can balance the scratch resistance of an image on a recording medium and the clogging recovery of a nozzle of an ink jet head. The ink jet recording method includes an ink attachment step, in which a water-based ink composition is ejected from an ink jet head and attached to a recording medium, and a heating step, in which the recording medium is heated, after the ink attachment step. The water-based ink composition contains resin particles and wax. The resin particles have a volume-average diameter A of 90.0 nm or more, and the ratio between the volume-average diameter A of the resin particles and the volume-average diameter B of the particles of the wax (B / A) is 0.7 or more. The heating step is through irradiation with infrared light.
Description
technical field [0001] The present invention relates to an inkjet recording method and an inkjet recording apparatus. Background technique [0002] There is known an inkjet recording method in which tiny ink droplets are ejected from the nozzles of an inkjet head of an inkjet recording device to record an image on a recording medium, and this inkjet recording method is also being studied for use in the field of logo printing, high-speed label printing, etc. use in the field. Also, when recording an image on a recording medium with low ink absorption (such as coated paper or coated paper) or a non-absorbent recording medium (such as a plastic film), as ink, it is harmful to the earth's environment and the human body. From the standpoint of safety and the like, the use of water-based resin ink compositions containing resin emulsions (hereinafter sometimes simply referred to as "water-based ink compositions" or "water-based inks") is being studied. [0003] A water-based ink ...
