To provide such a printing correction method as compensates the manufacturing error of a relief printing plate and a displacement in the laying of the relief printing plate, by improving a method by which a printing mark is printed on matter-to-be-printed 10 by using a registration device for a multicolor printer and detected by a sensor, or an printing image is at least partially detected according to image evaluation, by which evaluation is performed in the registration device, and by which respective different printing lengths among the individual printers are compensated by controlling the motion of the matter-to-be-printed, or individual printers and/or the correction of the carrying of a web.
At least one of first printing marks 51 and at least one of second printing marks 52 are printed in every production and printing step; the first and second printing marks are compared with a reference point or a reference area so that registration can be performed; and/or the registration is performed on the basis of comparison between comparison image data and data acquired from the detection of the printing image.
