ABSTRACT:
Application to areas of the successive rollers and cylinders in a printing press, of liquid from the water duct which will not eventually be transferred to the material being printed, is avoided by using a vibrator roller and at least one damper roller of the same width as the sheet of material being printed, while the oscillator roller, the plate cylinder, the blanket cylinder and the impression cylinder are wider than the sheet.
