PURPOSE:To perform precise positional adjustment of a screen form of each printing station and whereby enable continuous printing without any shift of each color pattern by printing on a member to be marked in a positional relationship which is equal to a relative positional relationship between the original position of a screen form to be arranged after the second printing station and the arrangement position of a detection means. CONSTITUTION:A sensitive mark which a detection means 11 arranged outside a screen form 9b of a printing station 5b becomes a sensitive mark Mx which is printed simultaneously with the printing of the first color pattern 8 in a segmented part 7X. Consequently, the positional relationship between each segmented part 7 and a sensitive mark M which is printed at the same time as printing into each segmented part 7 at the first printing station 5a, is always maintained to a prearranged distance L. Consequently, the position of the screen form 9b is horizontally adjusted by means of a position adjustment device to meet said segmented part 7X securely. This enables the second color pattern 8 to be superimposed on the first color pattern 8 without any shift.
