The purpose of printer color calibration is to ensure accurate color reproduction and to maintain the color consistency. A closed loop color calibration system has the ability to perform the whole calibration work automatically without any user intervention. A color calibration process consists of several steps: print a pre-designed target; measure the printed color patches using an color measuring instrument; run a set of algorithms to calibrate the color variations. In this paper, we present a closed loop color calibration system. And we will show in particular how to use a low cost optical sensor to get accurate color measurement. Traditional, low cost optical sensors are only used to measure the voltage data or density data. The novelty of our approach is that we can also use a low cost optical sensor to measure colorimetric data. Using the colorimetric measurement, we can perform more complicate color calibration works for color printing systems.
