Color printers and computer 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 get the most out of them.   

The TekColor color correction options are available for a finer degree of 
control over colors.  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.
