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.
How is color specified in a document to be printed?
Software programs typically specify document color using RGB or CMYK color combinations. Additionally, they
allow users to modify the color of each object in a document. For more information, see the software program
Help topics.
How does the printer know what color to print?
When a user prints a document, information describing the type and color of each object is sent to the printer. The
color information is passed through color conversion tables that translate the color into the appropriate amounts
of cyan, magenta, yellow, and black toner needed to produce the desired color. 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.
