Print quality examination device

A multicolor offset printing press includes a first blanket cylinder, at least four plate cylinders, a collecting plate cylinder, a collecting blanket cylinder, at least two partial plate cylinders, and a plurality of ink devices. The first blanket cylinder performs printing on a transported target printing product. The four plate cylinders are in contact with the first blanket cylinder. The collecting plate cylinder is in contact with the first blanket cylinder on the downstream side in the rotational direction of the first blanket cylinder with respect to a last plate cylinder positioned on the most downstream side in the rotational direction of the first blanket cylinder among the four plate cylinders, and on the upstream side in the rotational direction of the first blanket cylinder with respect to a printing portion at which the first blanket cylinder performs printing on the target printing product. The collecting blanket cylinder is in contact with the collecting plate cylinder and transfers ink to the collecting plate cylinder. The two partial plate cylinders are in contact with the collecting blanket cylinder. The plurality of ink devices supply inks to the four plate cylinders and the two partial plate cylinders, respectively.
