Abstract

A common problem in the field of color printing is closed loop color calibration, a process which generally requires a spectrometer. Light Emitting Diodes (LED) sensors are inexpensive and effective for measuring the net reflectance of certain frequencies of light. Sensor measurement of LED reflectance can be used to estimate spectral reflectance or color value (measured in CIELAB or CIEXYZ color space) of a printed patch. LED based sensors suffer from their lower accuracy in predicting color values. This paper focuses on improving accuracy of these sensors in predicting Lightness values in CIELAB color space of a single colorant by combining information from multiple LEDs with different spectrum coverage.
