In one of our previous paper [1] proposed in the last year, we described the color management pipeline that applied to our nail inkjet printer. However, the resulting prints are not as vivid as we would like to have since those prints are not well saturated. In this paper, we propose a saturation enhancement method based on the image segmentation and hue angle. This method will not necessarily give us the closest representation of the colors within the input image but could give us more saturated prints. The main idea that we perform our saturation enhancement method is to keep the lightness and hue constant, while stretching the chroma component.
