Epson T0423 (T042340) Files ink is a Magenta cartridge which is 16ml in capacity. Epson T0423 uses DURABrite pigment ink. Epson DURABrite inks deliver ideal solution for everyday text and image printing. DURABrite inks are optimized for plain and matte papers yet also offer the flexibility to print photos. DURABrite Inks are useful where high quality, long-lasting output is desired. In addition, prints are durable that are water, smudge, and fade-resistant. DURABrite pigment ink uses an exclusive Micro encapsulation technology where each pigment particle is encased in a resin. A unique polymer pulls the particles apart so they are suspended in the solution and never coagulate. The ink base then helps the DURABrite pigment particles penetrate into the paper. DURABrite pigment ink produces excellent output on Epson glossy photo papers as well.
