CMYK is an acronym for cyan, magenta, yellow, and key. These are the colors used for printing and are part of subtractive coloring. They allow a broad spectrum of colors when combined. The term "key" is often thought to be black, and though it is the most often used, it is in fact a variable color. Computer monitors display RGB or additive color. So, when printing an image from the computer, the colors may be altered due the conversion.
