Each HP 831A ink cartridge contains 775ml of genuine HP Latex ink, providing a convenient replacement supply for busy sign shops and commercial print environments.
The cartridge-based ink system allows operators to replace individual colors as needed, helping maintain production without purchasing an entire ink set for every replenishment.
HP Latex printing technology produces durable, scratch-resistant graphics on compatible media, making these inks suitable for a variety of indoor and outdoor sign and display applications.
From self-adhesive vinyl and banners to wall graphics, posters, and retail displays, HP Latex inks provide versatile output for professional printing businesses. Actual durability depends on the media, application, environmental exposure, and protective finishing used.
Compatible HP Latex 300 and 500 Series printers use a six-color ink configuration consisting of Cyan, Magenta, Yellow, Black, Light Cyan, and Light Magenta, along with a dedicated Latex Optimizer.
The light ink colors support smooth tonal transitions and detailed graphics, while HP Latex Optimizer helps control ink placement during printing. This improves image quality and helps reduce unwanted ink bleed on compatible substrates.
Important: HP Latex Optimizer is a separate consumable used by the printer's ink system. It is not interchangeable with a color ink cartridge.
Each individual cartridge option contains 775ml of the selected ink color or optimizer. Confirm the required HP part number before ordering.
HP 831A 775ml ink cartridges and HP 831 Latex Optimizer are designed for compatible HP Latex 300 and 500 Series printing systems.
Compatibility Note: HP Latex 570 systems use 775ml cartridges as intermediate ink tanks and may also use separate 3-liter bulk ink supplies. Verify your printer's installed ink configuration and cartridge part numbers before purchasing. Compatibility with other HP Latex models should not be assumed.
Original HP ink and optimizer cartridges are designed specifically for compatible HP Latex printing systems. Using the correct OEM consumables helps support consistent print quality, dependable cartridge recognition, and proper operation of the printer's ink delivery system.

Ordering Note: Individual color and optimizer selections contain one 775ml cartridge. If a complete ink set option is offered, review its included quantities before purchasing. Printer, printheads, maintenance cartridges, and other consumables are sold separately.
