T770520 refill cartridge which supplies Light Cyan ink for the Epson SureColor P700.
Epson UltraChrome PRO10 Ink Set
The SureColor P700 uses Epson’s newest 10-color pigment ink set, UltraChrome PRO10. This new ink allows for a wider color gamut than previous generation printers in photographic and graphic design applications. The introduction of a violet ink channel helps to improve accuracy of blues, violets, and purples when printed, and the Advanced B&W mode still allows for perfectly neutral or custom-toned black-and-white photos.
These 25ml ink cartridges also allow for cost savings compared to smaller cartridges used in more consumer-based printers, and the PRO10 ink is industry leading in print permanence.
