REGISTER DETECTOR FOR FORM PRINTING/WORKING MACHINE, PRINT REGISTER MARK AND PRINTED/WORK PIECE

摘要

PROBLEM TO BE SOLVED: To provide a register detector for detecting a print register and working register for a form printing/working machine. SOLUTION: The register detector comprises a printing/working register imaging means for imaging a region including a print register mark of a form and a working mark at a downstream of a last part working unit, a data processing unit inputting imaging signals to convert the signals into printing/ working and to calculate a deviation amount of the print register and a deviation amount of the working register from image data, and a display unit for displaying the deviation amounts of the registers.
