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 the document color using RGB or CMYK color combinations. Additionally,
they let users modify the color of each object in a document. For more information, see the help information
of your operating system.
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 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 dierent color conversion table to photographic images.
