Method and apparatus for detecting and correcting misregistration of color separation planes in a multicolor printing process include the functions of: (i) printing on a test sheet, with a first color printing subsystem, a first array of M parallel lines which are uniformly spaced N adjustment steps apart and (ii) printing on the same test sheet with a second color printing subsystem, a second array of M parallel lines, which are uniformly spaced N+1 adjustment steps apart and which are predeterminedly juxtaposed, with respect to the lines of the first line array, so that when registration is correct, base registration lines of the first and second arrays are aligned. Upon visually inspecting the alignment of marks on said first and second line series, the operator can effect automated position shifting of the second subsystems printout color plane in an amount and direction based on which juxtaposed mark pair of said two arrays are in best alignment.
