The Epson 786 DURABrite Ultra Black Ink Cartridge Dual Pack features two black ink cartridges for select Epson WorkForce printers. They are standard capacity cartridges with pigment-based ink designed to give sharp, smudge- and water-resistant prints for general purpose applications. Due to how pigmented ink rests on the paper instead of being absorbed like dye-based inks, it produces sharper and brighter prints as well as limits bleed-through.
