10 Understanding color

Your printer gives you the power to communicate in color. Color attracts attention, commands respect, and adds value to your printed material or information. Using color increases readership and is read more often than the same material printed in black and white. Color can be used to motivate people and speed the analysis of complex data. When you print on-demand color, you save money.

To enhance your use and understanding about color printing, this section provides information about color and how to select, use, and adjust color for your network and desktop printing.

Types of color

To be effective, the use of color needs to be planned. The reason for this is how the eye sees color. When light is used to produce color on your monitor or TV, it uses three primary colors. They are red, green, and blue (also known as RGB color). All printed output such as newspapers, magazines, brochures, and of course your documents use the colors cyan, magenta, yellow, and black (known as CMYK color). Because the colors are presented to the eye differently, what you see on your monitor may look different than what you have printed. By understanding how we see color on the screen and how we see color in printed documents, we can better plan the use of color.

How we see color

When we see color, we actually see light that is passed through or reflected from an object. What our eyes perceive as visible light are wavelengths. Our eyes are sensitive to three specific wavelength colors: red, green, and blue.

When you look at your monitor, you see red, green, and blue light that is projected into your eyes. This additive color begins with black and adds red, green, and blue to produce the colors you can see. If you add equal amounts of red, green, and blue, you produce white. The images and colors you see on your screen are created using various amounts of red, green, and blue.
