摘要	Printing, marking or etching a surface is achieved using a mask or masks in combination with electromagnetic radiation (such as a laser or the like) or otherwise exposing one or more selected areas of a surface for treatment, utilising transmissive, non-transmissive or modified transmissivity portions of one or more layers of material of the mask. In one embodiment a surface of a first radiation transmissive layer of the mask is partially covered by a second layer of material which is substantially non-transmissive to radiation. An uncovered portion of the transmissive layer is in the shape of an element (such as a character, symbol or shape) to be printed, marked, etched or the like on the surface.
