Ink cartridge features a proprietary, pigment-based ink technology that provides the vibrancy of dye-based inks, but the durability of pigment-based inks. This design produces sharp text, brilliant color documents and photos that dry instantly and last a lifetime. The resulting photos are also water-resistant and fade-resistant. No. 30 cartridge is designed for use with Kodak ESP C100, C300, Hero 3.1, 5.1, and Office 2100 Series AiO Printers. Cartridge yields approximately 335 pages.
