Piezography Neutral K7 is a seven dilution ink set for smoothest possible tone reproduction with this model printer. These are the only "true" Neutral inks on the market today. The inks are designed to be used with QuadTone RIP ($50 shareware) or with StudioPrint RIP which has a built-in Piezography K7 ink profiler. StudioPrint requires a Spectrophotometer such as the X-Rite EyeOne Design or Photo.

Flush cartridges are highly recommended for this printer.
