Claim:
1. An ink curing apparatus comprising a UV lamp; at least two reflectors; and at least two moveable shutters, wherein movement of each shutter is between an open position exposing a substrate to UV radiation from the UV lamp and a closed position wherein the or each shutter shields the substrate from the UV radiation from the UV lamp, characterised in that each shutter is continuously moveable and is controlled by a crank mechanism; wherein the crank mechanism comprises at least two links attached to a rotatable shaft, wherein each link of the crank mechanism is attached to a connector, wherein each connector is attached to a shutter of the at least two moveable shutters, and wherein rotation of the rotatable shaft of the crank mechanism causes the at least two shutters to move away from each other towards a fully open position and continued rotation of the rotatable shaft of the crank mechanism in the same direction of rotation causes the at least two shutters to move towards each other towards a fully closed position.
