Color matching
The process of matching MFP 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:
● Print media
● Printer colorants (inks or toners for example)
● Printing process (inkjet, press, or laser technology for example)
● Overhead lighting
● Personal differences in perception of color
● Software applications
● Printer drivers
● Computer operating system
● Monitors
● Video cards and drivers
● 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 MFP 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

Sample book color matching
The process for matching MFP output to preprinted sample books and standard color references is
complex. In general, you can obtain a reasonably good match to a sample book if the inks used to create
the sample book are cyan, magenta, yellow, and black. These are usually referred to as process color
sample books.
Some sample books are created from spot colors. Spot colors are specially created colorants. Many of
these spot colors are outside of the range of the MFP. Most spot color sample books have companion
process sample books that provide CMYK approximations to the spot color.
