Description
The HP 727B 130-ml Gray Original DesignJet Ink Cartridge, part number 3WX15A, is a genuine HP ink supply designed for selected professional HP DesignJet T-series large-format printers and multifunction printers. Its dye-based Gray ink is formulated to produce smooth neutral tones, detailed grayscale transitions, accurate shading and professional-quality graphics across architectural drawings, engineering plans, CAD documents, maps, diagrams, presentations and large-format business graphics. The 130-ml capacity provides a practical standard-capacity solution for professional users with moderate regular printing requirements. Original HP DesignJet inks are engineered together with compatible HP printers and printheads to provide dependable ink flow, fast-drying output, smudge-resistant prints and consistent results. Gray ink plays an important role in the six-colour HP 727 printing system by improving grayscale reproduction and helping create smooth tonal transitions without relying entirely on composite colour inks.
