Abstract

A reflective mask for defining an image to be marked on an article using a laser beam (34) wherein the mask assembly (20, 40, 50) comprises reflective portions (32) defining the image. The mask (20) may comprise a plurality of individually selectable reflective elements (32) for defining an image, e.g. wheel members (26-29) each carrying several digits around its periphery, or wheel members each having a plurality of reflective elements around its periphery (Fig 4. not shown) or individually pivotable members arranged in arrays and each carrying a reflective element (Figs 5-8. not shown). <IMAGE>
