A method includes the steps of: pulsing a light emitting diode at a forward current level above continuous use operating limits to produce pulsed radiation within an absorption spectrum of the fluorescent material and at a flux density sufficient to induce a fluorescent emission from the indicia; illuminating the indicia with the pulsed radiation to produce the fluorescent emission; and imaging the indicia on a radiation image sensor sensitive to radiation within an emission spectrum of the fluorescence.
