Claims

[Scope of utility model registration request]

In an ink supply device of an offset rotary printing press, the ink is supplied from an ink tank to an ink source roller via a pump and an ink discharge nozzle, and is made into a constant film thickness by an ink supply blade, and then transferred to a doctor roller via a delivery roller. a porous material disposed near the tank; a heater that heats the ink tank to evaporate dampening water in the ink and attaches water vapor to the porous material; and a heater that reduces the pressure inside the porous material. An ink supply for an offset rotary printing press, characterized in that the dampening water is depressurized and separated by means for separating the dampening water from the ink by transmitting only the water vapor of the dampening water to the inside of the porous material. Device.
