Disclosed is a process for the detection of marked components of a composite article. The present invention relates to detecting the presence, position, concentration and/or distribution of one or more components in a composite article, and to registration inspection of a composite article using infrared radiation. In one embodiment of the invention, infrared blockers, such as absorbing infrared blockers, are incorporated into the component of interest in the composite to increase the visibility of the marked component during inspection.
