1. A process of inspecting a composite article having first and second panels in at least partially opposed, overlapping engagement with each other, the first panel having an underlying edge overlapped by at least a portion of the second panel which is substantially opaque to visible and/or ultraviolet light, said process to determine whether the panels of the article are present and/or properly positioned, said process comprising:

  • irradiating the overlapping engagement of the panels with radiation;

    producing an image from radiation received from the irradiated panels;

    identifying in the image a position of the underlying edge; and

    comparing the identified position of the underlying edge with a predetermined data to thereby determine whether the underlaying edge is present and/or properly positioned in the composite article.
