HP 775 500-ml Photo Black Ink Cartridge

This is the genuine HP 775 Photo Black ink cartridge for the HP DesignJet Z6 series, covering the 24-in, 44-in, Z6dr, and Z6 Pro models. Photo black is the ink to reach for when you need rich, detailed tonal range on photographic or high-quality poster prints.

Genuine HP ink is what HP designed and tested for the Z6 series, and it avoids the head-clogging issues that can come with third-party alternatives. Using other ink doesn’t by itself void HP’s warranty, but damage caused by non-HP ink isn’t covered. If your Z6 series printer is producing posters with images or photo content, this is the cartridge that handles that work.
