印刷機のインキ供給装置。 In the ink supply device of an offset rotary printing press, the ink is supplied from the ink tank through the pump and ink discharge nozzle to the ink source roller and made into a constant film thickness by the ink supply blade, and then transferred to the doctor roller via the delivery roller. A doctor roller made of the same porous material, a heater that heats ink containing dampening water adhering to the outer peripheral surface of the doctor roller made of the same porous material to evaporate the dampening water, and a heater that reduces the pressure inside the doctor roller made of the same porous material. What is claimed is: 1. An ink supply device for an offset rotary printing press, characterized in that the ink supply device is equipped with dampening water depressurization separation means for separating dampening water from ink by transmitting only water vapor of the dampening water toward the inside of a doctor roller.
