The C6170A (blue) Spot Color print cartridges have been designed for industrial printing applications that require spot colors to enhance their operations. Spot Color ink and thermal inkjet technology make color printing as quick, easy, and as affordable as monochrome printing, because it relies on easily replaceable ink cartridges rather than ink drums and 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. Spot Color print cartridges can be snapped in and out for easy replacement. These cartridges have a thermal sense resistor, which measures temperature, and enables thermal management and burnout protection for the printhead.
