The clear differentiation between colors of the original color image can get lost in an automatic conversion process, because the resulting gray shades may be adjacent. In magazines and newspapers this often results in gray images, which do not have very detailed shades. SilverFast SC2G (Selective Color to gray) can maintain the gray shade differentiation by controlling the conversion process. For all six colors (Red, Green, Blue, Cyan, Magenta, and Yellow) the user can control into what shade of gray the color will be converted. Since the whole process is interactively monitoring the final gray image, the user quickly achieves the desired result.
