    • The invention relates to a method of compensating for register deviations, which enables printing quality-reducing register deviations to be avoided at all printing or coating units of a rotary printing press. The method includes: a one-time determination of rotational vibrations in the driving gear train and of thereby caused register deviations between the printing or coating units only in the resonance regions of rotational speed under printing conditions within a rotary printing speed range; ascertaining counter-directed harmonic compensation moments from discrete harmonic portions of the rotational vibrations in the resonance range of rotational speeds; storing the parameters of the harmonic compensation moments and assigning them to the resonance ranges of rotational speed in the driving control system; and superimposing the stored compensation moments as a function of the rotational speed on the driving moment of the main drive motor in printing operation.
    • 本发明涉及补偿寄存器偏差的方法,这使得能够在旋转式印刷机的所有印刷或涂布单元处避免印刷质量降低的寄存器偏差。 该方法包括:一次性确定驱动齿轮系中的旋转振动,从而仅在旋转印刷速度范围内的打印条件下在旋转速度的共振区域中引起印刷或涂布单元之间的对准偏差; 确定在转速的共振范围内的旋转振动的离散谐波部分的反向谐波补偿力矩; 存储谐波补偿力矩的参数并将其分配给驱动控制系统中的转速的共振范围; 并且在打印操作中将存储的补偿力矩作为转速的函数叠加在主驱动电动机的驱动力矩上。

    • The invention relates to a method of compensating for register deviations, caused by rotational vibrations, in a sheet-fed rotary printing press with a driving gear train, connecting a sheet-feeding apparatus and printing units and/or coating units, and a main drive motor, acting on the driving gear train, to which a drive control is assigned. It is an object of the invention to configure a method, which reduces rotational vibration-induced register deviations and, with the least effort, enables printing quality-reducing register deviations to be avoided at all printing or coating units of a rotary printing press by a process with the following steps: single determination of rotational vibrations in the driving gear train and of thereby caused register deviations between the printing or coating units in the resonance regions of rotational speed under printing conditions within a rotary printing speed range, ascertaining counter-directed harmonic compensation moments from discrete harmonic portions of the rotational vibrations in the resonance range of rotational speeds, storing the parameters of the harmonic compensation moments and assigning them to the resonance ranges of rotational speed in the driving control system and superimposing the stored compensation moments as a function of the rotational speed on the driving moment of the main drive motor in printing operation.
