HP designed the Spot Color print cartridges for industrial printing applications that require spot colors to enhance their operations. HP's Spot Color ink & thermal inkjet technology make color printing quick, easy, & as affordable as monochrome printing because it relies on easily replaceable ink cartridges rather than ink drums & plates. These print cartridges are designed to print 600 dots per inch in applications where high-quality output on porous media is required. Integrated Driver Head (IDH) technology coordinates individual nozzles through a multiplexing scheme that fires all 300 nozzles through 52 interconnect pads. HP Spot Color print cartridges can be snapped in & out for easy replacement. These cartridges have a thermal sense resistor, which measures temperature, & enables thermal management & burnout protection for the print head.
