The problem that ColorSync solves
Providing consistent color with desktop computers is a technical challenge because different color devices use different methods for representing color, and they produce different ranges of colors. For example, the colored light on your monitor is very different from the colored inks your printer uses.
Different color devices also create color using different methods. Monitors (and most scanners) produce colors by mixing red, green, and blue light— called RGB color. Most printers produce colors by mixing cyan (a shade of blue), magenta (a bright pink), yellow, and black ink. This color system is called CMYK. Since monitors, printers, and scanners each have different color capabilities, they cannot reproduce each other’s colors exactly.
