  • Patent number: 12661920
    Abstract: A recording method includes a treatment liquid attachment step, a white ink attachment step, and a non-white ink attachment step. The white ink attachment step and the non-white ink attachment step are each performed by scanning while the ink jet head is moved with respect to the recording medium in a state where a position is fixed. The white ink composition is attached to a scanning region in one scanning and, the non-white ink composition is attached to a scanning region in one scanning. Scanning in another step is performed by another scanning, and in the white ink attachment step and the non-white ink attachment step, a surface temperature of the recording medium is 35° C. or lower.
