ABSTRACT:
A sheet-fed offset printing press with a convertible press mechanism includes a convertible cylinder, an impression cylinder, converting grippers and suckers, and grooves. The convertible cylinder conveys a paper sheet downstream with respect to a paper convey direction in a converted state. The impression cylinder is in contact with the convertible cylinder on an upstream side with respect to the paper convey direction, and conveys the paper sheet to the convertible cylinder. The converting grippers and suckers are provided to the convertible cylinder and separate the paper sheet wound on a circumferential surface of the impression cylinder and convert the separated paper sheet. The grooves are formed in an outermost circumferential surface of the impression cylinder including a circumferential surface of the impression cylinder. The outermost circumferential surface of the impression cylinder comes into direct contact with the paper sheet which is conveyed to the convertible cylinder.
