Claims
- 1. In a printing press with a plate registration control device, an automatic plate exchange method which adjusts the position relationship of a plate cylinder relative to other cylinders in contact with the plate cylinder, said method comprising the steps of:
- storing by the plate registration control device of a current position of said plate cylinder relative to the other cylinders when the plate cylinder is selected for plate exchange, said current position capable of dynamically varying from one plate exchange to the next,
- resetting by the plate registration control device of said plate cylinder to an origin after storage of said current position of said plate cylinder,
- after said plate cylinder is reset to said origin, performing automatic plate exchange to replace an old plate with a new plate in a state in which said plate cylinder is positioned to said origin, and
- returning by the plate registration control device of the plate cylinder with said exchanged new plate to said stored current position.
- 2. An automatic plate control apparatus of a printing press which adjusts the position relationship of a plate cylinder relative to other cylinders in contact with said plate cylinder, comprising:
- a plate registration control unit, including,
- storage means for storing a current position of said plate cylinder relative to said other cylinders when said plate cylinder is selected for plate exchange, said current position capable of dynamically varying from one plate exchange to the next,
- reset means for resetting said plate cylinder to an origin, and
- return means for returning said plate cylinder with a new plate to the stored current position; and
- an automatic plate exchange unit including,
- plate exchange means for performing automatic plate exchange to replace an old plate with said new plate in a state in which said plate cylinder is positioned to said origin.
