HP 771A Photo Black Cartridge

The HP 771A B6Y21A is a genuine pigment-based ink cartridge formulated for professional photo output. It serves print shops and graphics professionals using compatible HP DesignJet wide-format printers. The single-pack unit delivers consistent colour density for posters, fine art and indoor display graphics.

775 ml Capacity for High-Volume Runs

A 775 ml fill supports extended production of photo-quality POP displays, maps and backlit signs without frequent swaps. The large volume reduces intervention during long print queues and helps maintain cost efficiency on high-coverage jobs. Very low-volume users may find the cartridge size exceeds their throughput before the ink expiry window.

Stable Output with Pigment Ink Chemistry

Pigment-based formulation resists fading on a range of HP media for interior display permanence rated by HP Image Permanence Lab and Wilhelm Imaging Research. The 4 pl drop size enables sharp detail at high speeds while the ink chemistry minimises printhead clogging during daily operation. No active cooling or special power requirements are involved.
