The Epson 115 Photo Black ink bottle is designed for the Claria ET Premium line, providing a 70 ml supply of dye-based ink in black for high-quality photo printing. This ink is compatible with the EcoTank L8160 and L8180 printers, where it can produce up to 2300 black pages before needing a refill. To make maintenance simple, the bottle features a color-keyed nozzle that ensures a mess-free filling process by preventing the wrong color from being used in a tank. Because of the stability of the Claria ET Premium formula, photos stored in an album can remain vibrant for up to 300 years, making it a reliable choice for those who want to preserve family memories in physical form.
