PROBLEM TO BE SOLVED: To provide a registering mark which enables correct determination of the positions of individual color inks and a printing plate with this registering mark. SOLUTION: The registering mark 10 has a first ruled line 11 extending in a first direction and a second ruled line 12 extending in a second direction which is orthogonal with the first direction. In addition, the registering mark 10 has a first auxiliary ruled line 13 jutting out in the second direction from one end side of the longer direction of the first ruled line 11, a first indication part 14 formed at the tip part of the first auxiliary ruled line 13, a second auxiliary ruled line 15 jutting out in the first direction from one end side, in the longer direction, of the second ruled line 12 and a second indication part 16 formed at the tip part of the second auxiliary ruled line 15. Further, the distances between one ends, in the longer direction, of the first and the second ruled line 11 and 12 and the first and the second auxiliary ruled line 13 and 15, vary depending upon the colors of printing inks. |
