An inkjet printing apparatus for printing on a substrate comprises a first support, which is a substrate support, and a second support which supports at least one inkjet printing head, at least one UV source of ultraviolet radiation, and at least one gas dispenser. The second support is moveable relative to a substrate supported by the first support. The printing head deposits ink on the substrate and the UV source cures the deposited ink. The gas dispenser is arranged to provide a layer of gas, which is at least depleted of oxygen, between the UV source and the substrate.
