The Epson C13T642100 (T6421) 150 ml Black Ink Cartridge is an original, high-capacity pigment ink cartridge engineered for use with the Epson Stylus Pro 7890 wide-format printer. Designed to meet professional printing demands, this cartridge delivers deep, dense blacks and exceptional tonal range, making it ideal for technical drafts, photographic prints, fine art reproduction, and large-scale display graphics.
With its 150 ml volume, the T6421 supports extended print runs-minimizing interruptions and reducing ink-change frequency-so production workflows stay efficient and continuous. The pigment-based ink formulation offers outstanding durability, resisting water, smudging, and fading. This ensures that printed materials remain crisp and intact over time, whether displayed indoors or in areas subject to occasional handling or humidity exposure.
Engineered to work seamlessly with Epson`s PrecisionCore printhead technology, the cartridge ensures consistent ink flow and stable output quality across the print area. It delivers sharp lines, smooth gradients, and even solid coverage-critical for maintaining image and text quality in high-resolution or high-density prints.
Installation is straightforward: the cartridge is user-friendly and integrates cleanly with the Stylus Pro 7890`s ink delivery system, helping to reduce waste and prevent clogging. As an OEM product, it guarantees compatibility, maximum colour accuracy, and peak printer performance, avoiding the variability that can come with third-party inks.
Ideal for professionals who demand reliability and archival-grade results, the Epson T6421 Black Cartridge offers the capacity, longevity, and image fidelity needed for gallery exhibitions, technical plotting, and high-quality graphic production.
