inkjet cartridge - Computer Definition
A replaceable unit that holds ink and the print nozzles for inkjet printers. A separate cartridge for each of the four CMYK colors is the most efficient. Low-cost printers include cyan, magenta and yellow inks in one cartridge, requiring the entire unit be replaced when one color is empty. The least efficient is a single cartridge that contains all four colors. More Than Four Cartridges Although the four CMYK inks are the standard for color printing, inkjet manufacturers have added inks of varying colors, claiming an improvement in the overall result. First in higher-end inkjet printers, six- and eight-cartridge printers followed in consumer models after the turn of the century. See ink coverage.
