Abstract

The most obvious difference between digital photofinishing and other color reproduction devices, such as printer, is its exposure mechanism. So the color control system is based on the analysis of exposure characteristic. To offset the colorimetric shift by developer, three target density curves are proposed and applied to the pre-adjustment of exposure mechanism. Since the color control system is considered static via pre-adjustment, it can be modeled by the color space transform from colorimetric space to dye space. By comparison, the neural network method is utilized to realize this transform. To get uniform samples in CIE Lab color space for network, a cumulative dye slicing method is designed. At last, the GretagMacbeth ColorChecker color rendition chart is printed, and the results indicate that this color control system achieves the color difference requirement of high-quality reproduction.
