Abstract
PURPOSE:To enable improvement of an emulsified state of ink on a plate sur face, removal of foreign matter, and prevention of a ghost to be performed, by a method wherein a fountain roller, a soaking roller, and a plate cylinder are respectively independently driven with different motors. CONSTITUTION:When a fountain roller velocity command is set with a dial 13, input is transmitted to an inverter 12. A geared motor 11 is rotated at a setting speed to rotate the fountain roller 2. The more is the number of rotations of the fountain roller 2, the more water rises via a water transfer roller 3, and a soaking roller 6, and much water is adhered to a surface of a plate cylinder. When a slippage command is set to a dial 19, a veliocity command is outputted from a mixer 20 by operating the setting value and the number of rotations of the plate cylinder Nm, which is inputted to an inverter 18. A geared motor 17 is rotated at a command velocity, and the soaking roller 6 is rotated at the command velocity via a clutch 15. That is, the number of rotations of the soaking roller 6 or the number of rotations of the fountain roller 2 to the plate cylinder can be independently freely regulated.
