ABSTRACT:
A fluorescence dot area meter for accurately measuring halftone dot area on a printing plate having an emulsion containing one or more fluorescent compounds. The fluorescent dot area meter generally includes an illumination source for providing light having a first range of wavelengths, a system for exposing the printing plate to this light to cause the printing plate to emit light (fluoresce) within a second, higher range of wavelengths, and a system for determining halftone dot area based on a measurement of the light emitted by the printing plate.
