A method and system for applying a two dimensional mark on a first surface of a component and assessing mark quality, the method comprising the steps of positioning a component with a first surface at a first station, applying a two dimensional mark to the first surface at the first station wherein the applied mark is intended to codify a first information subset, obtaining an image of the applied two dimensional mark at the first station using a stationary camera that has a field of view that is centered along a trajectory that forms an obtuse angle with at least a portion of the first surface and that includes at least a portion of the first surface, performing a mark quality assessment on the obtained image and performing a secondary function as a result of the mark quality assessment.
