    • A printing system has a first printer apparatus for forming an image on a first plane of a web having no feed holes and a second printer apparatus provided at a post stage following the first printer apparatus for forming an image on a second plane of said web. The first printer apparatus (P1) is operable to form a position-alignment mark (Rm) at a predesignated position on each page of a web. This position-alignment mark is detected by mark detection means of the second printer apparatus (P2). Control means is provided for controlling the web transport speed so that both the generation timing of a web feed control signal (CPF-N signal) being generated with preset cyclic periods and the generation timing of a mark detection signal issued from the mark detection means through detection of the position-alignment mark are kept constant in phase.
    • 打印系统具有第一打印机装置,用于在没有进纸孔的纸幅的第一平面上形成图像;以及第二打印机装置,设置在第一打印机装置之后的第一打印机装置上,用于在所述纸幅的第二平面上形成图像。 第一打印机设备(P1)可操作以在网页的每一页上的预定位置处形成位置对准标记(Rm)。 该位置对准标记由第二打印机装置(P2)的标记检测装置检测。 提供控制装置,用于控制纸幅传送速度,使得以预设的循环周期生成纸幅馈送控制信号(CPF-N信号)的生成定时以及从标记检测装置发出的标记检测信号的生成定时 位置对准标记的检测保持相位恒定。
