Matching colors
The process of matching printer output color to your computer screen
is quite complex because printers and computer monitors use
different methods of producing color. Monitors display colors by light
pixels using an RGB (red, green, blue) color process, but printers
print colors using a CMYK (cyan, magenta, yellow, and black)
process.
Several factors can influence your ability to match printed colors to
those on your monitor. These factors include:
z
print media
z
printer colorants (inks or toners for example)
z printing process (inkjet, press, or laser technology for example)
z
overhead lighting
z
personal differences in perception of color
z
software applications
z
printer drivers
z PC operating system
z
monitors
z video cards and drivers
z operating environment (humidity for example)
Keep the above factors in mind when colors on your screen do not
perfectly match your printed colors.
For most users, the best method for matching colors on your screen
to your printer is to print sRGB colors.
PANTONE®* color matching
PANTONE®* has multiple color matching systems. PANTONE®*
Matching System is very popular and uses solid inks to generate a
wide range of color hues and tints. See

on how to use PANTONE®* Matching System with this printer.
Swatch book color matching
The process for matching printer output to preprinted swatch books
and standard color references is complex. In general, you can obtain
a reasonably good match to a swatch book if the inks used to create
the swatch book are cyan, magenta, yellow, and black. These are
usually referred to as process color swatch books.
