ABSTRACT:
A method for conditioning a printing ink in a printing press includes providing an ink duct roller and a metering device, operating the ink duct roller in conjunction with the metering device for liquefying the printing ink before a start of printing, and providing a further roller for removing the printing ink from the ink duct roller. Removal of the printing ink from the ink duct roller by the further roller is held in a suppressed state, while simultaneously rotating the ink duct roller at a conditioning rotational speed, and simultaneously controlling the metering device pursuant to a conditioning profile, for only partially opening the metering device at least intermittently. A printing press for performing the method is also provided.
