Invention is our legacy. We invented inkjet printing more than twenty years ago and have led the printing market ever since. Today, HP's 17,000 worldwide patents represent a $4 billion annual R&D investment, fueling everything from print technology to molecular computing. We believe it is vitally important to maintain this level of R&D investment—it's the only way to achieve breakthrough technology that improves so many facets of business and life.
The world's leading ink inventor
HP ink is the center of the inkjet print system, driving critical attributes such as print quality, durability and reliability. Even the smallest impurity can lead to printhead clogging, significantly decreasing print quality over time. So each HP ink goes through 20 tests for purity and more than 50 tests for essential ink qualities, such as water resistance, fade resistance and color. In fact, it can take us up to four years and more than 1000 different formulas until we're satisfied with the ink's test results.
Technology drives HP inkjet supplies
HP inkjet print cartridges contain more than specially formulated inks. Each contains an integrated circuit, precisely routing signals to the correct ink nozzle—one of more than 500 nozzles, each one only about one-third the diameter of a human hair—with exact timing. Why such advanced technology? Because it's the only way to achieve the precise dot placement required for crisp images, sharp black and vivid colors, and reliable output.
HP Quality means long-term value
Quality and reliability help boost productivity and cut costs. That's why HP inks and print cartridges are designed and tested together as a system with HP printers and papers. Why is this important? Because it drives unsurpassed reliability that helps you avoid printer downtime, lost productivity and wasted supplies. That's time and money you could better spend on your business.
