Abstract
The present invention discloses a method and apparatus for imaging and cutting a label from a linerless label substrate, the substratecomprising: a paper or polymeric film base layer; a colour change layer, incorporating a colour change compound operable to change colour in response to illumination by a laser; an adhesive layer; and a release layer adapted to have low adherence to the adhesive layer. The label substrateis transported from a storage reel to an imaging area. At the imaging area, the label substrateis selectively illuminated by laserto form an image in the colour change layer. Subsequently, further laser illumination is used to cut the label substratethereby providing a single label for application to an object. The invention is characterised in that the laser spot size is varied for imaging and cutting.
