Abstract
A method and system are provided for establishing a reference position of ink-metering elements relative to a duct roller of a printing machine. The reference position is established by moving the ink-metering element toward the duct roller while acoustically sensing for contact. When a noise level indicative of the ink-metering element being in contact with the roller is detected, the reference, or zero position is established. At that precise moment, a representative value which varies with the distance between the element and the roller is stored as the zero position.
