1. A spray dyeing method, comprising:
continuously moving a substrate in a direction;
spraying an organic pigment onto the substrate using a spraying system while moving the substrate forward through a dyeing station; and
allowing the substrate coated with the organic pigment to pass through a drying station including an infrared irradiation unit to cure the organic pigment,
wherein curing the organic pigment comprises:
irradiating infrared light in a first wavelength band onto the substrate coated with the organic pigment; and
after irradiating the infrared light in the first wavelength band, irradiating infrared light in a second wavelength band onto the substrate, wherein the second wavelength band is different from the first wavelength band.
