Epson T7023 XL (T702340) Eiffel Tower ink is a magenta cartridge which is 21.3ml in capacity. Epson T7023 uses DURABrite Ultra pigment ink. Epson DURABrite Ultra delivers laser-sharp print quality for everyday text documents on plain paper and outstanding photo printing on glossy paper. In addition, prints are durable that are water, smudge, and fade-resistant. DURABrite Ultra 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 Ultra pigment particles penetrate into the paper. DURABrite Ultra pigment ink produces excellent output on Epson glossy photo papers as well.
