Abstract

To obviate local differences in heat expansion in the ink duct, ink metering means and ductor roller, and to temper the printing ink, stabilize the ink-damping agent emulsion and protect the ductor roller from corrosion, the ink duct includes a heat insulating material secured to underside of the duct body and a mid-section portion of the duct body side facing the ductor roller is supplied with a warm air flow from the printing press, boosted by a plurality of fans.
