Abstract: A method for measuring the radiant exposure of energy curable inks or coatings on a printing press. The steps for measuring comprise: a) providing an ink or coating material comprising a fluorescent probe; b) transferring the ink or coating material onto a substrate using a printing process; c) exposing the ink or coating material to actinic radiation capable of initiating cure of the ink or coating material that also alters the luminescence of the probe; d) exposing the ink or coating to a first source of excitation light with wavelength and luminance capable of absorption by the fluorescent probe; and e) measuring the emitted light from the fluorescent probe by a first detector.
