Abstract
A printing press includes a printing cylinder, inkjet heads, and an ink drying lamp. A non-metal sheet is attached to an outer surface of the printing cylinder. The non-metal sheet includes a main body made of a non-metal material in a sheet-like shape, and a plurality of ventilation portions through which air passes in a thickness direction of the main body. This makes it possible to efficiently dissipate heat of the printing cylinder while preventing the printing cylinder from being overheated when an amount of heat generated at the time of printing is transferred to the surface of the printing cylinder.
