Abstract: A pretreatment device includes: a medium support portion configured to support a medium that is transported; a pretreatment-agent ejecting portion configured to eject a pretreatment agent; an absorbing-member support portion configured to support an absorbing member between the medium and the pretreatment-agent ejecting portion in a direction in which the pretreatment agent is ejected, the absorbing member being configured to absorb the pretreatment agent ejected from the pretreatment-agent ejecting portion; and a pressing unit configured to press, toward the medium, the absorbing member to which the pretreatment agent is ejected from the pretreatment-agent ejecting portion.

Abstract: An ink jet ink composition set includes a white ink jet ink composition and a nonwhite ink jet ink composition. The white ink jet ink composition contains a white pigment, resin particles, and water, and the nonwhite ink jet ink composition contains a nonwhite pigment, resin particles, and water. The white pigment has cation responsiveness, and the absolute value of zeta potential of the white pigment is lower than the absolute value of zeta potential of the nonwhite pigment.

Abstract: A non-white textile printing ink jet ink composition according to the present disclosure contains a pigment, a resin particle, an acetylene-based surfactant having an HLB value of 6 or more and 10 or less, and water, wherein a content of the acetylene-based surfactant is 0.5% by mass or more and 2.0% by mass or less relative to a total amount of the ink composition, and the ink composition is used for a fabric having water absorbency evaluated using a method described below is 1 or more, method: a test fabric cut into 2 cm square is mounted on a water surface in a glass bottle which has a volume of 50 mL and in which 30 mL of pure water is introduced so that a height from a bottom to the water surface is 4 cm, a fabric surface being set to be parallel to the water surface, and a time elapsed from the fabric being mounted until a portion of the fabric reaching the bottom of the glass bottle is denoted as water absorbency in seconds.

Abstract: A white ink jet ink composition according to the present disclosure includes hollow resin particles, resin particles, and water. The hollow resin particles have a glass transition temperature of 120° C. or more, the resin particles are composed of an acrylic resin or a urethane resin, and the content of the resin particles is 5% by mass or more relative to the total mass of the ink composition.

Abstract: A white ink jet ink composition including hollow resin particles, resin particles, and water, in which a glass transition temperature of the hollow resin particles is 120° C. or higher, and a glass transition temperature of the resin particles is 5° C. or lower.
