Proprietary Epson technology employing three shades of black is the key to truly professional black-and-white photo printing. A richer range of tonal expression is possible with no twists or casts in black-and-white photo reproduction, giving life-like artistry to the prints. The lightest black in the Ink colour palette renders extremely smooth black-and-white tonal gradations, from the deepest shadows to the lightest highlights, resulting in excellent volume perception.
