Characterizing the desktop color printer with polynomial regression

In many application areas, the printer has played a key role of reproducing the digital color images. According to the characteristics of output devices, the uncorrected distortion has arisen in the reproduced color. This paper proposed the color correction based on polynomial regressions that represented the characteristics of the desktop color printer. In addition, the proper number of sample used in obtaining the regression equation was investigated. The experiments showed the possibilities of the proposed methods by comparing the ΔEab value between the original color and the corresponding reproduced color
