Genuine HP 70 Light Gray Cartridge

The HP C9451A is a genuine HP 70 series ink cartridge containing 130 ml of pigment-based light gray ink. It is designed for professional photo and fine-art printing on compatible HP DesignJet large-format printers. The cartridge uses HP Thermal Inkjet technology for consistent output.

Replaces depleted HP 70 Light Gray supply

This single-pack cartridge replaces an empty HP 70 light gray tank in DesignJet Z2100, Z3100, Z3200, Z5200 and Z5400 series printers, including 24 inch and 44 inch models. The upgrade is worth it when prints show missing gray tones or the printer signals low ink for this specific channel.

130 ml pigment ink for grayscale depth

The 130 ml volume supports extended print runs of monochrome images, neutral grayscales and subtle color blends where light gray is critical. Pigment formulation delivers archival permanence rated over 200 years on HP creative media. It runs out during high-volume production of black-and-white photography or proofing workflows.
