Four-color printing is a method of color printing using the three primary colors (yellow, magenta, cyan) and black in the subtractive color process. It is a method of color printing using four colors: yellow (Y), magenta (M), cyan (C) and black (BK). If a printing process using other colors other than yellow, magenta, cyan and black inks to reproduce the original color is used, it should not be called "four-color printing" but "spot color printing"
