Abstract: A heating unit heats a sheet. A first measuring unit measures or estimates a first temperature of surface of the sheet before the sheet is conveyed to the heating unit. A heating control unit controls an output of the heating unit, in such a manner that the first temperature output from the first measuring unit becomes equal to or higher than a first predetermined temperature that is necessary for drying a water-based varnish coated on a surface of an ink that is transferred onto one side of the sheet.

Abstract: An apparatus and a method in which when both of two-stage type and impression cylinder connecting type sheet-fed perfecting multi-color printing presses are manufactured, there is no need for a manufacture of extra parts or an extra stock, and also the replacement and servicing of parts are easy in the event of a failure of a printing unit or the sheet-fed perfecting multi-color printing press. For this purpose, modules for the printing unit for the sheet-fed perfecting multi-color printing press, each of which consists of a combination of at least two elements of a group consisting of an intermediate cylinder, impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism are manufactured, and the modules are used to manufacture the two-stage type and impression cylinder connecting type sheet-fed perfecting multi-color printing presses.

Abstract: An intermediate cylinder comprising a main body, and a plurality of suction boxes formed in the main body at positions different with respect to a rotation axis of the main body. The intermediate cylinder further comprises a plurality of suction bores formed in the suction boxes so that they are open at an outer peripheral surface of the main body, an air suction source for generating suction force within the suction boxes, and a switching means for selectively switching connections between the plurality of suction boxes and the air suction source.
