HP High Definition Nozzle Architecture (HDNA) provides a true 2400dpi from 2 rows of offset print nozzles at a 1200 nozzles per inch density per inch definition - Twice the nozzle density of non-HDNA HP printheads.
HP 746 Printhead HDNA is one of the foundation building blocks of the Z6 Z9+ system which enables faster print speeds while not trading off image quality. The renewed printer portfolio helps your business to do more with less, so greater quality using fewer inks and fewer printheads.
• True 2400 dpi: Twice the nozzle density as non-HDNA
• Smart nozzle utilization: System will choose either full nozzle capability for maximum ink flow at fast print speeds or alternate nozzle use allowing nozzle rest
• Improved error hiding: Both adjacent AND newly added direct nozzle redundancy
• More consistent ink drop generation across the entire nozzle plate: Additional heat resistors at printhead edges
