FAQ about color printing

What is RGB color?
RGB color is a method of describing colors by indicating the amount of red, green, or blue used to produce
a certain color. Red, green, and blue light can be added in various amounts to produce a large range of colors
observed in nature. Computer screens, scanners, and digital cameras use this method to display colors.
What is CMYK color?
CMYK color is a method of describing colors by indicating the amount of cyan, magenta, yellow, and black
used to reproduce a particular 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. Printing presses, inkjet printers, and color
laser printers create colors in this manner.
How is color specified in a document to be printed?
Software programs are used to specify and modify the document color using RGB or CMYK color
combinations. For more information, see the software program Help topics.
