Hold grayscale fidelity where it matters most. Epson Ultrachrome PRO10 Gray Ink Cartridge, MPN T46Y700, delivers a 50 mL OEM supply for select Epson photo printers using the Ultrachrome PRO10 ink set. Gray ink plays a critical role in neutral rendering, helping maintain subtle tonal separation in black-and-white work, soft gradients, and mixed-color images that require disciplined shadow control. For studios, labs, and in-house production teams, this cartridge supports consistent output from job to job without forcing color correction around an off-balance gray channel. The OEM formulation is designed to integrate with Epson print systems, reducing guesswork during media changes and keeping output aligned with the printer’s intended color behavior. That matters when the work is client-facing, archived, or part of a repeatable proofing process. Choose this cartridge when print quality is measured in nuance, not just coverage. The 50 mL fill size offers a practical balance between capacity and inventory control for professional environments that need dependable replenishment and exact model matching.
