Abstract
A method for inspecting a feature applied to a box blank during manufacture of a paper box, comprising the steps of illuminating at least that portion of box blank including the feature with an illumination source, receiving an image of the illuminated portion of the box blank from at least one optical sensor, varying a characteristic of the illumination source for optically distinguishing between the feature a surface of said portion of the box blank to which the feature is applied, comparing the received image to a stored product profile containing an optimal image of the feature to determine if features in the received image are similar to the features in the stored product profile, and using the comparison to indicate when the box blank does not conform to the product profile.
