  • Patent number: 10265973
    Abstract: A recording method includes applying an ink composition onto a recording medium, primarily drying the recording medium during the application of the ink composition, transporting the recording medium applied the ink composition to a secondary drying device, and secondarily drying the recording medium with the secondary drying device. The variation in surface temperature of the recording medium from the primary drying temperature (T1) to the lowest temperature and the variation in surface temperature of the recording medium from T1 to the highest temperature, in the period from completion of the application of the ink composition to completion of the secondary drying are ?40% or more and 370% or less, respectively, relative to T1. The surface temperature of the recording medium is increased to the secondary drying temperature at an average rate of 7° C./s or less after the completion of the application of the ink composition.
