Dye printing treatment liquid composition, composition set, printing method, and ink jet printing method

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.

Ink jet ink composition set and ink jet recording method

An ink jet printing recording apparatus includes a belt which supports a recording medium; a heating portion which heats the belt; and an ink jet recording head which ejects an ink jet ink composition, the belt is provided with an adhesive layer, the ink jet ink composition contains a heat cross-linking component, and the belt is heated by the heating portion to a temperature lower than a reaction temperature of the heat cross-linking component.

Ink jet printing recording apparatus and ink jet recording method

An ink jet recording method according to the present disclosure is a method for recording on a textile including ejecting a white ink composition for ink jet textile printing containing a white pigment and water with an ink jet recording apparatus, wherein the white ink composition is ejected as 9 ng or less of droplets from a nozzle, and the droplets are ejected and recorded on the textile such that a droplet ejected later has a higher flight speed than a droplet ejected earlier and the droplets coalesce before landing on the textile.

Ink jet recording method

A liquid discharge apparatus of the present disclosure includes an ink composition and a liquid discharge section including a nozzle for discharging the ink composition. The ink composition is a pigment textile printing ink composition containing resin particles, water, and an organic solvent. The resin particles have a glass transition temperature of 5&#xb0; C. or less and are contained in an amount of 6.5 mass % or more based on the total amount of the ink composition. The ink composition contains a polyhydric alcohol having a boiling point of 270&#xb0; C. or more as the organic solvent in an amount of 15.0 mass % or less based on the total amount of the ink composition. The liquid discharge section includes a pressure chamber and a circulation passage for circulating the ink composition in the pressure chamber.

Liquid discharge apparatus, ink jet recording method, and pigment textile printing ink composition

A treatment liquid composition contains water, 1,2-alkanediol, and an aggregating agent aggregating or thickening components of an ink composition containing a pigment and is used for a printing method performed by causing the ink composition to adhere to cloth by an ink jet method.
