file that matches your 
monitor to improve on-screen color matching. Exact color matching is ver\
y difficult. Check your software and 
monitor documentation for information on color matching and calibration.\
 
Mac OS X: Use the color management system for your computer, ColorSync. Exact col\
or matching is very

color systems: monitors use RGB (red, green, and blue) and printers ty\
pically use CMYK (cyan, magenta, yellow, 
and black).Top
