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.

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.

Why doesn't the printed color match the color I see on the computer screen?
The color conversion tables used in Auto Color Correction mode generally approximate the colors of a standard
computer monitor. However, because of technology differences that exist between printers and monitors, there are
many colors that can also be affected by monitor variations and lighting conditions. For recommendations on how

can I match a particular color (such as a corporate logo)?”
The printed page appears tinted. Can I adjust the color?
Sometimes a printed page may appear tinted (for example, everything printed seems to be too red). This can be
caused by environmental conditions, paper type, lighting conditions, or user preference. In these instances, adjust
the Color Balance setting to create a more preferable color. Color Balance provides the user with the ability to make
subtle adjustments to the amount of toner being used in each color plane. Selecting positive or negative values for
cyan, magenta, yellow, and black (from the Color Balance menu) will slightly increase or decrease the amount of
toner used for the chosen color. For example, if a printed page has a red tint, then decreasing both magenta and
yellow could potentially improve the color balance.
