Epson T55K400 Yellow Ink UltraChrome HD 700ml OEM

Epson T55K400 Yellow Ink UltraChrome HD 700ml OEM is genuine Epson pigment ink designed for SureColor large format photo printers that use the T55K series cartridges, including the Epson SureColor P6000, P7000, P8000, and P9000. Yellow is a core color in the UltraChrome HD ink set and plays a major role in accurate warm highlights, natural skin tones, sunsets, and smooth transitions in lighter areas where banding or shifts are easier to notice. When yellow stays stable across runs, it helps you match prior prints and keep color consistent for proofs, reorders, and longer production jobs.

UltraChrome HD and UltraChrome HDX ink systems are engineered to work as a complete Epson printer and media workflow for predictable color, reliable daily performance, and repeatable output. Using the correct OEM ink helps reduce variables that can cause shifts between runs, which can save time, paper, and ink when you are producing client work or color critical projects. With the right media settings and ICC profiles, yellow tones remain predictable and consistent from print to print.

This product is a 700ml OEM ink cartridge, part number T55K400, color Yellow. Label Code: T55K. Always confirm your printer model and required ink series before ordering.
