HP 771A B6Y16A 775-ml Chromatic Red ink cartridges (genuine brands)

HP 771A Chromatic Red Cartridge

The HP 771A B6Y16A is a genuine Chromatic Red ink cartridge holding 775 ml of pigment-based ink. It is designed for HP DesignJet large-format printers that use the 771A series. Professional print shops and in-house graphics departments use it to produce consistent red tones on technical drawings, posters and photographic output.

Pigment Ink Environmental Limits

Pigment-based ink requires stable conditions to maintain viscosity and prevent nozzle clogging. The cartridge operates reliably between 64 and 77 °F with humidity from 20 to 80 % RH. Storage outside the printer is rated from -40 to 140 °F and 15 to 90 % RH. Exceeding these ranges can cause colour shift or permanent printhead damage.

High-Capacity Replacement For Standard Cartridges

This 775 ml cartridge replaces lower-capacity Chromatic Red supplies that require frequent changes during long print runs. The jump is worthwhile when daily output exceeds the yield of smaller cartridges and downtime for swaps affects deadlines. It is not suited for occasional low-volume printing where ink may settle before the cartridge is depleted.
