Claim 0:
1. A temperature adjustment device for a printing machine, which adjusts temperatures of rollers in a plurality of inking devices mounted in the printing machine by supplying temperature-regulated water to shaft parts of the rollers, the temperature adjustment device comprising:
a plurality of smoothing function roller temperature regulators, provided respectively corresponding to the inking devices, and each adjusting a temperature of an ink smoothing function roller among a series of rollers in each of the inking devices;
a hot water supply unit that supplies hot water of a preset temperature to the ink smoothing function roller when the printing machine comes to a temporary halt; and
a control unit that controls the smoothing function roller temperature regulators and the hot water supply unit, wherein
the control unit has a function of executing control in
a high-temperature mode in which the smoothing function roller temperature regulators are operated at a temperature set higher than a preset reference temperature,
a middle-temperature mode in which the smoothing function roller temperature regulators are operated at a temperature set higher than the preset reference temperature and lower than a set temperature of the high-temperature mode,
a normal operation mode in which the smoothing function roller temperature regulators are operated at the preset reference temperature, and
a temporary stop mode in which when the printing machine comes to a temporary halt, operation of the smoothing function roller temperature regulators is stopped, as well as the hot water is supplied from the hot water supply unit to the ink smoothing function rollers.
