Match colors
The process of matching product output color to a 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 the ability to match printed colors to those on a monitor. These factors
include:
● Paper
● 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 programs
● Print drivers
● Computer operating system
● Monitors and monitor settings
● Video cards and drivers
● Operating environment (humidity for example)
For most situations, the best method for matching colors on the screen to the printed page is to print
sRGB colors.
Sample book color matching
The process for matching product 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 product. Most spot color sample books have
companion process sample books that provide CMYK approximations to the spot color.
Most process sample books will state which process standards were used to print the sample book.
In most cases they will be SWOP, EURO, or DIC. To get optimal color matching to the process
sample book, select the corresponding ink emulation from the product menu. If you cannot identify
the process standard, use SWOP ink emulation.
Print color samples
To use the color samples, select the color sample that is the closest match to the desired color. Use
the sample’s color value in the software program to describe the object you wish to match. Printed
colors vary depending on the paper type and the software program.
Use the following procedure to print color samples at the product using the control panel:
