A system that measures deviation of printed color at selected locations on a moving substrate from a target color. The system comprises using a printed test image of target color, a calibrated spectrophotometer to provide spectral response values of the target color on the test image, a photonic device that provides tri-stimulus values from inline printed images and a computing device. The computing device compares the tri-stimulus values to spectral response values for the test image to calculate a spectral transformation matrix at each location selected to remove variations in optical and mechanical parameters. The spectral transformation matrix is applied to future mapped sets of tri-stimulus values of printed colors captured by the photonic device from selected locations to determine in real-time the deviation of color and thereby control color quality.
