Printing machine and method of operating a printing machine

摘要

A method of operating a printing machine including an inking unit having a vibrator roller oscillatable reciprocatingly between an ink-duct roller and an inking-unit roller for making intermittent contact with the rollers, includes selectively operating the inking unit in a normal operating mode and in at least one reduced-ink operating mode wherein the ink-duct roller rotates with a movement characteristic different from that of the normal operating mode; a control method for the operating method; and a device for performing the operating method.
