Abstract
A marking device and method using a plate holder with a printing plate attached, an X-Y-Z driver which moves the plate holder in the X, Y and Z directions, a camera installed downstream of the printing position on a work piece feeding line so that the camera photographs the character width and position of the character printed on the work piece, and a computer which calculates the difference between the width of the printed character and predetermined standard character width and/or the discrepancy in the printed character position. The computer further alters, for the next work piece, the amount of imprinting movement of the printing plate into the work piece and/or the printed character position by controlling the X-Y-Z driver based upon the data representing the difference in the printed character width and/or the data representing the discrepancy in the printed character position.
