  • Apparatus and method for compensating for slip of a printing-plate sleeve
    Patent number: 6314883
    Abstract: In order to compensate for slippage of a printing-plate sleeve on the plate cylinder of a printing unit having its own motor, a first reference point for the position of the printing plate is sensed by a sensor. The first reference point is then compared with the position of a reference printing-plate sleeve of a reference printing unit. A motor during the printing unit is then readjusted when there is a determined deviation from the desired position.
