    • Printing material is transported through the multicolor printing machine with a cyclically operating feeding arrangement. At least one surface of the printing material is successively imprinted with a printed image. The printed image is recorded in a image pickup and an image signal of each printed image is generated. The image signal generated from a plurality of printed images is transmitted to a control device. The control device processes the electric image signals to obtain information relating to rhythmic vibrations in the machine causing register deviations. The cause of the vibrations is determined and counter-measures are initiated for minimizing or eliminating the rhythmic vibrations.
    • 印刷材料通过多色印刷机通过循环操作的进料装置输送。 印刷材料的至少一个表面被连续地印刷有印刷图像。 打印的图像被记录在图像拾取器中,并且生成每个打印图像的图像信号。 从多个打印图像生成的图像信号被发送到控制装置。 控制装置处理电图像信号以获得与机器中节奏振动有关的信息引起寄存器偏差的信息。 确定振动的原因,并且开始对抗措施以最小化或消除节奏振动。

    • An inking control system for a printing machine has an operating panel with operating and display elements for adjusting the zonally acting ink distribution devices in the printing machine. A spacing distribution along a given direction and a number of the operating and display elements corresponds to a spacing distribution and a number of the ink zones in the printing machine. A full size color monitor is integrated in the operating panel. The color monitor is enabled to display a full-size printed image on a scale of 1:1 and to spatially correlate the display of the printed image with the operating and display elements to directly visually associate the inking zones in the displayed printed image with the operating and display elements. One or more image recording devices in the printing machine record printed images while the printing material is conveyed through the printing machine. The acquired image data are forwarded to a computer that is connected to the ink distribution devices and to the one or more image recording devices. In the method, the display image for the screen is generated from a sequence of successive scans by the image recording device.
    • 用于印刷机的上墨控制系统具有操作面板,该操作面板具有操作和显示元件,用于调节印刷机中的分区式墨水分配装置。 沿着给定方向的间隔分布和操作和显示元件的数量对应于印刷机中的间隔分布和数量的墨区。 操作面板集成了全尺寸彩色显示器。 彩色显示器能够以1:1的比例显示全尺寸打印图像,并将打印图像的显示与操作和显示元素空间相关,以直接将显示的打印图像中的着墨区域与 操作和显示元素。 打印机中的一个或多个图像记录装置在通过打印机输送打印材料的同时记录打印图像。 所获取的图像数据被转发到连接到墨水分配装置和一个或多个图像记录装置的计算机。 在该方法中,通过图像记录装置的连续扫描序列生成用于屏幕的显示图像。

    • A method for image position correction in printing on a printing material, wherein the printing material is traveling along a travel path through a printing machine by devices of a transporting arrangement, and wherein a positioning device is provided for aligning the distances and parallelities of the printed image in relation to the edges of the printing material, the method which includes generating by devices of at least one image pickup device disposed in the travel path of the printing material image signals from at least one surface of the printing material, wherein the image signals contain information pertaining to the distances and parallelity of the printed image in relation to the edges of the printed material, transmitting the image signals to a steering- or control device, and adjusting with the steering- or control device by means of signals applied to aforesaid positioning device the printed image so as to attain alignment of the image in relation to the distances from and parallelity with the edges of the printing material.
    • 一种用于打印在打印材料上的图像位置校正的方法,其中所述打印材料通过传送装置的装置沿着通过打印机的行进路径行进,并且其中提供定位装置以对准所印刷的距离和平行度 图像相关于打印材料的边缘的方法,该方法包括由设置在打印材料的行进路径中的至少一个图像拾取装置的设备产生来自打印材料的至少一个表面的图像信号,其中图像信号 包含关于印刷图像相对于印刷材料的边缘的距离和平行性的信息,将图像信号传输到转向或控制装置,并且通过施加到前述的信号用转向或控制装置进行调节 定位装置打印图像,以便使图像相对于距离的距离达到对准 并与印刷材料的边缘平行。
