Key Features
HP Vivid Photo Inks
HP describes the 773 DesignJet cartridges as delivering the quality you expect and meeting fast turnaround times, even for top photo-quality applications. The range pairs pigment-based ink with HP Thermal Inkjet printing, so it suits print jobs where image quality is the priority.
775 ml in Every Cartridge
Each cartridge holds 775 ml of ink and ships on its own, with the cartridge as the only item in the box. HP files it under Standard Capacity Ink Cartridges and lists the 773C selectability code, so you can match it to the printer's ink set.
One Part Number per Colour
Every colour has its own HP part number, from C1Q37A for Matte Black through to C1Q44A for Light Gray, so you can order exactly the colours your printer has run low on. The full list sits in the Colours and Part Numbers tab.
