CMY or Cyan-Magenta-Yellow:  The standard set of subtractive, processing colors used in printing.  Color printing devices use discrete dots of cyan, magenta and yellow to present the appearance of a full-color image to the human eye.  The combination of cyan, magenta and yellow produces black.  However, some printers include black ink along with the above three colors, which is properly called CMYK.
