If you're a photographer, you probably use an inkjet printer, most likely an expanded-gamut inkjet printer—one that uses six to eight inks, rather than the standard four (they're technically dyes, but most folks call them inks). The most common combination of expanded-gamut ink includes the four standard process colors—cyan, magenta, yellow and black (CMYK)—plus light cyan and light magenta. You may also have a choice of black inks, like glossy or photo black, matte black, light black, and even light light black (seriously!).
