To ensure sufficient energy for curing an ultraviolet-curable ink in a printing machine capable of printing in the ultraviolet-curable ink.

A drying apparatus 10 for a printing machine cures the ultraviolet-curable ink of printed matter printed in the ultraviolet-curable ink. The drying apparatus 10 for the printing machine is includes a UV-LED unit 11 and a UV lamp 12. The UV-LED unit 11 irradiates a sheet 5 after printed by a printing unit 31 for primary processing with ultraviolet rays. The UV lamp 12 receives the sheet 5 irradiated with the ultraviolet rays by the UV-LED unit 11, and is provided in an intermediate cylinder 25b delivered to the impression cylinder 32c of the printing unit 32 for the primary processing. The UV lamp 12 irradiates the sheet 5 irradiated with the ultraviolet rays by the UV-LED unit 11 with the ultraviolet rays.
