    摘要: A method for regulating the ink-to-wetting agent equilibrium in a rotary offset printing machine, the wetting agent quantity being determined especially using the signals of a sensor which measures the light reflectance of an area on the printing form of the rotary printing machine that is wetted by a wetting agent. The method includes: presetting the wetting agent quantity supplied to the printing form, calibrating the wetting agent quantity supplied at an ink quantity that is essentially kept constant, adjusting the wetting agent quantity to a wetting agent quantity setpoint value that is characteristic for the specific print job, increasing or decreasing the ink quantity from an ink quantity setpoint value to an ink quantity target value that is desirable for the printing job to be processed, and a corresponding increasing or decreasing of the wetting agent quantity setpoint value in the same direction to a wetting agent quantity target value, and regulating the supplied wetting agent quantity in a closed control loop as a function of the wetting agent quantity target value.

    摘要: A sleeve-shaped printing element for mounting on a carrying cylinder in a printing unit of a web-processing rotary printing machine. The element includes a structure formed of material permitting radial expansion of the sleeve-shaped printing element, the carrying cylinder has an elongated axial extent and being formed with ducts for discharging an expansion medium. The ducts open on a circumferential surface of the carrying cylinder, and the expansion medium is pressurizable by a pressure source. The sleeve-shaped printing element is formed with an inner diameter increasing from one end to the other end of the printing element, and is formed with an at least approximately constant wall thickness; and a combination of the printing element and the carrying cylinder.
