Sheet-fed printing press having a dryer for drying sheets printed by a non-impact printing device

A sheet-fed printing press comprising:

• a dryer (17) that dries sheets (64) printed by a non-impact printing device (13), the dryer (17) configured as a hot air dryer and/or as a dryer drying by infrared (IR) radiation, and
• a cooling unit (36) arranged directly downstream from the dryer (17) in a transport direction (T) of the sheets (64), the cooling unit (36) comprising at least one cooling module (37) above a conveying plane (E) in which the sheets (64) are conveyed through the cooling unit (36) lying flat, and the at least one cooling module (37) configured to use air as a cooling medium, characterized in that each at least one cooling module (37) of the cooling unit (36) includes a respective blower module (41), the respective blower module (41) configured to guide the cooling medium onto surfaces of the sheets (64) to be cooled, the respective blower module (41) comprising a plurality of blower nozzles (43), the cooling medium being blown through the plurality of blower nozzles (43) onto a surface of a respective sheet (64) to be cooled, the respective blower module (41) configured to form, with a guide surface (42), a space (S37) between the guide surface (42) and the surface of the respective sheet (64) to be cooled, the space between the guide surface (42) of the respective blower module (41) and the surface of the relevant sheet (64) to be cooled arranged such that a cross-section of an outer annular gap formed by the space (S37), and through which a volume flow of the cooling medium exists, is smaller than or almost equal to a sum cross-section across all opening surfaces of the blower nozzles (43) in the guide surface (42) to provide a pressurized flow of the cooling medium across the surface of the respective sheet (64) to be cooled as the cooling medium passes from the nozzles (43) and exits the annular gap.
