A method of calibrating a laser marking system of the type comprising a plurality of emitters, each emitter operable to emit light on to a substrate for marking, the output light energy of each emitter being modulated by varying a marking setting for each emitter is disclosed. The method comprises the steps of: activating the emitters to mark a series of block images on to the substrate using a series of different marking settings; capturing an image of each marked block; processing the captured images to determine the optical density of the areas of the marked block associated with each individual emitter and thereby determining an optical density value for each emitter for each of the utilised marking settings; and performing an interpolation to determine marking settings corresponding to optical density values for intermediate marking settings between the utilised marking settings wherein the determined marking settings for each optical density value for each emitter are stored in a look up table and if there are marking settings having different parameter values that correspond to the same optical density value, the method involves selecting one marking setting only for storage in the look up table. In addition, an alternate method of calibrating a laser marking system of the above type, comprising extracting an intensity profile through the image in a direction substantially perpendicular to the relative motion between the substrate and the emitters is also described.
