摘要： What is disclosed is a novel system and method to reduce noise induced by color mixing in a color management system. At least one device color recipe is obtained for a target spot color. The recipe is defined for a color marking device and defines a range of marking device color values for a target L*a*b color value. Next, a minimal value and a maximum value of each color value in the range of color values for said target L*a*b color value are identified. An iterative process of searching is performed until the printed color test patch produces a visually acceptable smoothness while matching color accuracy. This iterative process includes generating at least one additional new device color recipe from color values within the range of color values. At least one of the new device color recipes is selected and provided to the color marking device for rendering.
