The range of colors within a device-independent color space, such as CIELAB, which are producible on a color output device or system is referred to as its gamut. While it is popular to show two-dimensional projections (e.g., onto the a*, b* plane), color gamuts are actually
three-dimensional, and contain much more information and features than can be shown in such a projection. In order to show these features, more elaborate techniques must be used. These include three dimensional modeling and shading, production of different cross sections, and projections to
supplement the (a*, b*) projection. Applications for printer color gamuts include: • General Gamut Visualization • Comparison to two device gamuts • Gamut Volume computation and comparison • Investigation of the effect of change of illuminant •
Investigation of the effect of change in colorant set, substrate, halftoning method, or other conditions • Colorant Set Optimization • Inclusion of a specific color The presentation will discuss several visualization techniques, and compare their utility for these applications.
Practical examples will be presented for each of these applications.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
