FAQ about color printing
What is RGB color?
Red, green, and blue light can be added together in various amounts to produce a large range of colors observed in
nature. For example, red and green can be combined to create yellow. Televisions and computer monitors create
colors in this manner. RGB color is a method of describing colors by indicating the amount of red, green, or blue
needed to produce a certain color.
What is CMYK color?
Cyan, magenta, yellow, and black inks or toners can be printed in various amounts to produce a large range of colors
observed in nature. For example, cyan and yellow can be combined to create green. Printing presses, inkjet printers,
and color laser printers create colors in this manner. CMYK color is a method of describing colors by indicating the
amount of cyan, magenta, yellow, and black needed to reproduce a particular color.
