    Abstract: Methods and devices print markings on an item in a first printing pass, using intended locations for the markings, to produce initial printed marks. Such methods and devices further scan the item after the first printing pass to detect actual printed locations of the initial printed marks. These methods and devices also compare the actual printed locations to the intended locations to identify the printing registration variation. Thus, such methods and devices change the intended locations for the markings based on the printing registration variation to generate corrected locations for the markings; and then reprint the markings directly on the initial printed marks a second time on the item in a second printing pass using the corrected locations for the markings, using the marking device.

    Abstract translation: 方法和装置在第一次打印通行证中的项目上打印标记,使用标记的预期位置来生成初始打印标记。 这样的方法和装置在第一次打印通过之后进一步扫描物品以检测初始打印标记的实际打印位置。 这些方法和装置还将实际印刷位置与预期位置进行比较,以识别印刷登记变化。 因此,这样的方法和装置基于打印登记变化改变用于标记的预期位置,以产生用于标记的校正位置; 然后使用标记装置,使用校正的标记位置,在第二次打印过程中再次直接在初始打印标记上重新打印初始打印标记上的标记。
