A printing system for metallic sheets (18) comprises a printer including a print drum arranged to carry the sheets past ink applicators; a curing oven (34) for curing ink applied to the sheets; and, below the curing oven, a cooling station (93). A key feature of the system is transfer apparatus (47) for transferring the sheets from edge-to-edge motion in one direction through the curing oven to face-to-face motion in the opposite direction through the cooling station. This apparatus comprises a transfer conveyor (48) defining a generally curved conveyor path (56) and having magnets (66) to locate the sheets (18) in the path. At a downstream end (72) of this path, the sheets are flung towards a slow-moving conveyor (74) of the cooling station, which has an overhead magnetic rail (85) to hold the top edges of the sheets to the underside of the belt (76) of the conveyor as they pass in spaced relation through the cooling station. |
