Problem-free printing saves time which saves money

Original HP Photo Inks are designed for problem-free printing with exclusive dispersion technology.

Original HP Photo Ink is specifically engineered to deliver consistent results every time you print. Carefully selected ultra-pure pigments and exclusive ink formulation technology ensure that pigment particles remain evenly dispersed and ink flows freely. This prevents settling and clumping of particles that can clog printhead nozzles and cause inconsistent print quality. Original HP Photo Ink takes the hassle out of getting brilliant, vivid color—that you can repeat—print after print.

HP 2-packs and individually replaceable ink cartridges make printing easy and cost-effective.

Avoid waste and rework—HP media and Original HP Photo Inks are designed together to work together.

Original HP Photo Ink and HP's broad portfolio of photo, fine-art and proofing media have been designed together to do the job right. More than 80 tests may be conducted on the print attributes of the ink and media to ensure the highest-quality results possible. You get color accuracy and consistency you can count on. So you can skip the waste and rework.

To ensure problem-free printing, Original HP Photo Inks are rigorously tested.

Unique Original HP Photo Inks are formulated through a process of rigorous testing. Ink chemists typically design up to 1000 prototype ink formulations that are subjected to hundreds of tests to see how the ink interacts with the cartridge, the printer and the media.
