Abstract: A recording method includes a white ink attachment step, in which a white ink composition containing a white colorant is attached to a recording medium; a non-white ink attachment step, in which a non-white ink composition containing a non-white colorant is attached to overlap the attached white ink composition; a first treatment liquid attachment step, accompanying the white ink attachment step and in which a treatment liquid containing a flocculant is attached to the recording medium; and a second treatment liquid attachment step, accompanying the non-white ink attachment step and in which a treatment liquid containing a flocculant is attached to the recording medium. The white ink composition experiences a five-fold or greater increase in viscosity when mixed with a 7% by mass aqueous solution of calcium formate in a ratio by mass of 10:1, the white ink composition to the aqueous solution of calcium formate. The attachment density of the treatment liquid in the second treatment liquid attachment step is lower than that in the first treatment liquid attachment step.

Abstract: An ink jet printing method includes a printing step of performing a plurality of times of scanning performed by ejecting a treatment liquid and an ink composition from an ink jet head having treatment liquid nozzles and ink nozzles that is being transferred in a scanning direction, thus applying the treatment liquid and the ink composition onto a printing medium. The ink jet head has an arrangement of treatment liquid ejection nozzles that includes a coincident portion, and an arrangement of ink ejection nozzles that includes a coincident portion, and the coincident portions are coincident in position in the sub-scanning direction with each other. In the printing step, the coincident portion of the arrangement of the treatment liquid ejection nozzles accounts for 60% or more of the length in the sub-scanning direction of the arrangement of the treatment liquid ejection nozzles, and the treatment liquid is applied onto a region of the printing medium in a proportion of from 20% by mass to 50% by mass relative to the ink composition applied onto the region.
