An ink supply apparatus of a printing press includes at least one inking device. In the inking device, an ink fountain roller is rotatably supported. An ink fountain main body forms a space to store an ink together with an outer surface of the ink fountain roller. A guide member slidably supports the ink fountain main body and guides the ink fountain main body between a first position where the space is formed and a second position spaced apart from the ink fountain roller than the first position. A doctor including a blade is attached to a doctor holding member between the ink fountain main body and the ink fountain roller when the ink fountain main body is located at the second position. The blade abuts against the ink fountain roller and cleans the ink fountain roller.

Disclosed is a contact-pressure adjusting method and a contact-pressure adjusting system, each of which automatically adjusts the contact pressure between two rotors, for a liquid application machine including: a first rotor to which liquid is supplied; a second rotor to which the liquid is supplied from the first rotor; and a contact-pressure adjusting unit for adjusting the contact pressure between the first rotor and the second rotor. By using a temperature measuring unit, measured is: the temperature of at least one of the surfaces of the first and second rotors; the temperature of at least one of the liquid on the surface of the first rotor and the liquid on the surface of the second rotor; or the temperature of at least one of the vicinity of the first rotor and the vicinity of the second rotor. The contact-pressure adjusting unit is adjusted in accordance with the measured temperature.

A sheet-fed printing press comprises a running transport chain, gripper devices supported by the transport chain and each having a gripper and a gripper pad for gripping a sheet, an inspection device for inspecting the sheet gripped and transported by the gripper devices, and a suction table having a guide surface for guiding the sheet at a position of inspection, and suction holes for spreading the sheet along the guide surface. Suction taper plates each having an inclined surface, which gradually decreases the distance between the gripper pads and the guide surface from an upstream side toward a downstream side of the guide surface in the sheet transport direction, are provided on the downstream side of the guide surface at predetermined intervals in the sheet width direction. Grooves, through which the grippers pass, are interposed among the suction taper plates.
