Overview

The HP 728 Cyan Ink Cartridge (F9J63A) is a 40 ml genuine HP ink cartridge engineered specifically for the HP DesignJet T830 MFP and T730 large format plotter printers. It uses HP Bright Office DesignJet Ink, a dye-based cyan formulation that produces vivid colors with sharp line quality—critical for architectural drawings, GIS maps, posters, and other large-format documents where every detail must be clearly distinguishable.

HP's dual ink technology pairs bright dye-based color inks with pigment-based black ink to achieve bold images, true neutral grays, and water-resistant output on plain paper. This combination supports collaborative review workflows where prints need to be handled, marked up, and stored without fading or smearing. The cartridge is designed as part of a closed system: HP formulates the ink, printhead, and printer firmware to work together, which helps maintain consistent output quality and reduces the risk of printhead failure associated with non-HP inks. The cartridge is also part of HP's closed-loop recycling initiative, making it a more environmentally responsible choice.

HP Bright Office Inks achieve outstanding line quality and bright color distinction to bring out every detail. Bold images, true neutral grays, and archival durability with water-resistant blacks.

HP 728 DesignJet ink is designed together with your HP DesignJet printer to deliver consistently high-quality prints on a wide range of media – saving you time, money, and ensuring your customers’ satisfaction.

HP’s dual ink technology is an innovative combination of the brightest dye-based color inks and permanent and water-resistant pigment-based black to bring out every detail on plain paper, enabling full and accurate communication.

Reliable alternative to remanufactured, compatible, and third-party replacement ink cartridges: While non-HP inks may cost less, they can cause frequent printhead replacement, unsellable prints – wasting time and money – and increased printer downtime.

Better for the environment than remanufactured inks: HP's groundbreaking closed loop recycling process uses plastic from recycled Original HP cartridges plus recycled bottles and hangers to create new Original HP cartridges.

Designed for and compatible with HP DesignJet T830 MFP & T730 Large Format Plotter Printers.
