Print text in true black and produce the sharpest monochrome graphics with the genuine Epson 16 black ink cartridge. The dye-based formulation of the Epson C13T16214010 black ink allows it to adhere easily onto any type of media to prevent smudging. Text won\'t bleed when printed on speciality paper because the ink dries quickly. The printer can perform better when the Epson T1621 ink cartridge works with the innovative Micro Piezo inkjet technology. The original Epson T1621 black ink cartridge is also made with the Acu Photo Halftoning system for more solid and rich output.
