Color deviation has always been an issue that needs to be addressed urgently in color printing. However, many factors influence the color quality of color printing, such as the material of the printed matter, the way in which the printed matter is processed before printing, the way in which the printed matter is processed after printing, and the manner in which it is printed. In the past, the color quality of the printed matter was controlled by the human eye and the rule of thumb was used to adjust the color deviation of the printed matter. However, the error of the human eye is large, and the sensitivity of each person's eyes to color is not the same, which makes it difficult to maintain the control of the color quality of the printed matter. The various colors of color printing are made up of several basic colors, such as moonlight, magenta and yellow. The human eye cannot accurately recognize the deviation of each color on the printed matter, which also causes the color quality to be biased, and cannot be accurately corrected by the human eye. For the above reasons, a system and method are needed for objective color quality analysis of printed matter.
