The Epson UltraChrome Pro 10 Ink 50ml is a professional quality ink available in 10 true colours. When used as a set, in the SC-P900 Epson printer, users benefit from K3 - 3 levels of black. This, along with the addition of the violet ink, delivers an expanded colour gamut for prints with an outstanding dynamic range. With this set of inks, users can create true monochrome work with no black ink switching. This is thanks to the dedicated photo and matte black ink channels. Deeper black and higher contrast are supported by the Black Enhancement Overcoat Technology. This effect is most prominent on glossy media.
