746 Ink Cartridge 300ml Set 6-Pack - Replacement for DesignJet Z6 Z9

In this review the reviewer tested the 746 Ink Cartridge 300ml set to see if it delivers reliable color output for large format DesignJet Z6 and Z9+ printers. The bottom line: this 6-pack replacement set is for print shops and designers who need full CMYK plus two blacks in one purchase and value consistent, predictable ink performance. It is praised for matching the expected color lineup and for offering a straightforward swap-in option, making it a practical choice for users who run frequent photo and matte projects and want to avoid mid-job cartridge changes.

Key Features

• Complete 6-Pack: Includes Photo Black, Matte Black, Cyan, Magenta, Yellow and Chromatic Red so users can replace all primary colors in one go and return to full printing quickly.
• 300ml Capacity: Each cartridge holds 300ml to support extended large format runs without frequent cartridge swaps during busy print jobs.
• DesignJet Compatibility: Labeled for use with DesignJet Z6 and Z9+ printers so installers can expect physical compatibility and an uncomplicated replacement process.
• Distinct Black Options: Offers both Photo Black and Matte Black cartridges which help achieve better shadow detail and appropriate blacks for glossy versus matte media.
• Color Coverage: The inclusion of Chromatic Red alongside CMYK improves gamut for photo and proofing work where richer reds matter.

Who It's For

This set is aimed at small commercial print shops, in-house design teams, and photographers who use HP DesignJet Z6 or Z9+ large format printers and need a single purchase to restore full color capability. It suits users running mixed media jobs that require both photo and matte black inks for accurate reproduction across paper types.

It is less suitable for occasional home users with low monthly page counts or users of other printer series; those customers should confirm their printer model first and consider single replacement cartridges or smaller capacity options to avoid excess inventory.

• Photo Black and Matte Black options provide flexibility for glossy and matte prints.
• 300ml cartridges reduce frequency of changes during long print runs and lower downtime.
