Spot Colors
Colors created without screens or dots, such as those found
in the PANTONE MATCHING SYSTEM®, are referred to in the
industry as spot or solid colors. From a palette of 14
basic colors, each of the spot colors in the PANTONE
MATCHING System is mixed according to its own unique ink
mixing formula developed by Pantone. You probably mixed
yellow and blue paint to get green in your youth. Creating
a PANTONE Spot color is similar in concept, but with the added need
for precision.
Mixing inks to create a PANTONE Color |
The precision begins with the printing ink manufacturers who
are licensed by Pantone to manufacture inks for mixing
PANTONE MATCHING SYSTEM Colors. To retain their license,
they must annually submit samples of the 14 basic colors
for approval by Pantone. Printers can then order the colors
by number or mix it themselves according to the ink mixing
formula in a PANTONE® FORMULA GUIDE. A PANTONE Chip supplied
with the ink and/or job ensures that the printer achieves the color
desired by the customer.

Each color in the System has a unique name or number
followed by either a C, U or M. The letter suffix refers to
the paper stock on which it is printed: C for Coated
paper, U for Uncoated paper and M for Matte paper. Also
created without screens, PANTONE metallic and pastel colors
are considered part of the PANTONE MATCHING SYSTEM.
Due to the gamut of the 14 basic colors, some spot colors
will be cleaner and brighter than if they were created
in the four-color process described below. Spot colors
are commonly used in corporate logos and identity
programs, and in one, two or three-color jobs.
Process Colors
This method of achieving color in printing is referred to as
CMYK, four–color process, 4/c process or even just
process. To reproduce a color image, a file is separated
into four different colors: Cyan (C), Magenta (M), Yellow
(Y) and Black (K).
A color image is separated into CMYK. When printed on paper, the original image is recreated.
During separation, screen tints comprised of small dots
are applied at different angles to each of the four
colors. The screened separations are then transferred to
four different printing plates, one for each color, and
run on a printing press with one color overprinting the
next. The composite image fools the naked eye with the illusion
of continuous tone.

Process colors are represented as percentages of cyan,
magenta, yellow and black. Varying the percentages offers
thousands of color possibilities. When four-color process
printing is used to reproduce photographs, decorative
elements such as borders and graphics can be created out of
process colors. This helps to avoid the added expense of an extra
plate needed to print each spot color.
Converting spot colors to process colors.
Often times, a spot PANTONE MATCHING SYSTEM Color is
requested when creating a four–color process piece. To
save money, the spot color should be evaluated to see how
it will look if printed in CMYK. While some colors can
be simulated well, there are many that look quite
different. As the quality of the resulting color conversion
is very subjective, the designer can make decisions using the
PANTONE® COLOR BRIDGE™ guide.
