The Epson C13T07K598 (also known as Epson 005 Grey or T07K5) is an original Grey Ink Bottle designed for specific, high-end Epson EcoTank (Ink Tank System) printers that utilize a multi-color ink setup, including an extra grey ink, for enhanced photographic quality.
 
Enhances Black and White (monochrome) printing by providing finer detail and smoother gradations without the color casts often seen when mixing CMY for grey. It also helps improve the neutral density and shadow detail in color photos.
Features Epson's unique key-locked bottle design for an easy, spill-free, and error-proof refilling process. The nozzle is uniquely shaped to fit only the Grey ink tank.
