FAQ about color printing
What is an 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 the 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. CMYK 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 colors in a document 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.
The information is then passed through color conversion tables. Color is translated into the appropriate
amounts of CMYK toners that are used to produce the color that 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 dierent color conversion table to photos.
