Using color corrections

Color printers and computer display screens produce color differently.
Printers use the subtractive primaries CMYK (cyan, magenta, yellow, and
black), and produce color when light is reflected off the paper. Computers
use the additive primaries RGB (red, green, blue) with a light-emitting CRT
screen. The printer and the computer screen each have a different range of
possible colors they can produce, with some overlap between them.

Software application packages specify color in different ways, for example as
CMYK or RGB, or they may give you a choice. Get to know your
applications so you can use color more effectively.

The TekColor color correction options are available for a finer degree of
control over color. Since no single color correction option can address all
uses, refer to the following table for the description that best fits your
printing situation, and try the suggested color correction.
