Paper Abstract

This paper deals with print quality control through a spectral color measurement. The aim is to estimate the spectral reflectance curve of each pixel of a printed sheet for a spectral matching with the reference image. The proposed method consists to perform a spectral characterization of the complete chain which includes the printing system and a digital trichromatic camera. First, the spectral printer model is presented and verified by experiments. Then, the camera spectral sensitivity curves are estimated through the capture of a color chart whose spectral reflectance curves have been previously measured. Finally, the spectral printer model is used to estimate the print spectral reflectance curves from camera responses.
