Abstract
A lateral register correcting device is capable of correcting register movement for a web by printing units. A register mark is printed on front and back sides of the web. A register correction control unit automatically controls a register correcting mechanism in real time based on a register correction amount derived by a pair of register cameras for detecting the register mark. A fan out correction control unit automatically controls a roller pressing mechanism in real time based on a fan out correction amount derived by a pair of fan out cameras for detecting the register mark.
