Abstract
A substrate-marking system comprises a substrate-marking apparatus and a substrate which is susceptible, or includes an additive which is susceptible, to changing colour upon irradiation. The apparatus comprises a laser diode for emitting a beam of laser light and a galvanometer for aligning a desired point on the substrate with the laser beam such that the laser beam irradiates the desired point thus causing the additive, in use, to change colour at the point.
