Prescan area The area in the SilverFast Lite main window where you can preview the item you're scanning. Resolution The amount of detail in an image, as measured in dots per inch (dpi) or dots per centimeter (dpcm) RGB Refers to red, green, and blue, the basic colors used to create all other colors on a monitor. Saturation The strength or intensity of a color based on the degree to which it lacks its complementary color. For example, a strongly saturated blue would have little or no yellow (its complementary color). A red with little saturation would have a lot of cyan (its complementary color) mixed in, and as a result, would look muddy or dark. Glossary Page 72
