<P>PROBLEM TO BE SOLVED: To provide a registering mark group which allows fine adjustment in a registering operation that is conventionally difficult to automate and is best suited for gravure printing with a long web pass, and a register fine adjustment device. <P>SOLUTION: In this registering mark group designed to have reference color registering marks to be shown at two spots such as the head and the rear of each color registering mark, the following components are provided: an image photographing means which photographs each registering mark group and obtains its photographed image as a still image, when the registering mark group is installed on both side end parts of traveling web printed matter; a detection position arithmetic means which calculates a detection position at each other color registering mark of the photographed image based on reference color marks at two spots; a target position arithmetic means which calculates a target position for registering at the registering mark of each other color reference mark according to the reference; and a correction level arithmetic means which calculates a correction level for registering based on a deviation between the detection position and the target position. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
