Epson UltraChrome HDR is the latest generation of pigment ink technology, now featuring ten colors, including new Orange and Green inks. Building on the advances of Epson UltraChrome K3 ink with vivid magenta, this technology offers dramatically enhanced print and color quality. Key features include three-level black ink for excellent gray balance and smooth tonal gradations. The inclusion of orange and green inks significantly expands the color gamut, particularly in the bright green to yellow and yellow to red ranges. The orange ink specifically reduces image grain in skin tone reproductions. This model is compatible with Epson Pro 7700/9700 printers.
