Epson engineered the T157320 157 Photo Vivid Magenta Ink Cartridge for the Epson R3000 Printer. Epson utilized their UltraChrome K3 technology to produce deeper, richer tones. With fine art printing in the front of their minds, Epson developed vivid magenta to bring out the true colors of something as delicate as a flame. Epson's advanced magenta pigments bring to life the browns and the reds of your prints. Control your prints with the Epson advanced tones.
