The method involves depositing an image X on a roller 10 using a curable ink B ejected from inkjet printheads 50. The image has an upper surface T and lower surface L so that as the roller rotates the upper surface of the image is exposed to a first radiant energy source 51 (e.g.UV light) to partially cure the image. The exposed image is then transferred to a receiving substrate A so that the upper and lower surfaces of the image are reversed in forming a transferred image Z on the substrate. A second radiant energy source 56 completes the curing of the image Z The roller may be preheated (31,Fig.2), wherein only one one radiant energy source is used to completely cure the image X. The roller can be replaced by a continuous belt or ribbon and the inkjet printheads by a thermal transfer printhead (Fig.4). Alternatively, the two types of printheads can be used in combination with a belt (Fig.5).
