9.2 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.
How does the printer know what color to print?
When printing a document, information describing the type and color of each object is sent to the printer and is
passed through color conversion tables. Color is translated into the appropriate amounts of cyan, magenta, yellow,
and black toner used to produce the color you want. The object information determines the application of color
conversion tables. For example, it is possible to apply one type of color conversion table to text while applying a
different color conversion table to photographic images.
