Spot color and four-color process are two different ways to print on anything—mouse pads,
paper, etc. For both processes there must be a
separate plate or screen (called a color separation) for each ink color to be printed. As you
might expect, the more colors to be printed, the
more plates are needed and the more expensive
the job is. In spot color printing the inks are
mixed by the manufacturer and are applied one
color to a plate. If “exact” color matching is
required, exact colors can be specified using
PMS (Pantone Matching System) numbers.
In four-color processing, four ink colors are
mixed together on the printing press to make
essentially all the colors of the rainbow. These
four-colors are usually called “CYMK” for
cyan (a light blue), magenta (a pinkish red), yellow and black inks.
If the job has only a few colors, spot color is an
economical way to print. However, if the job
has a lot of colors it can be less expensive to
print using four-color process. Photographs
must be printed using four-color process
because of the large number of colors they have.
