Color Gamut Mapping along Electrostatic Field Lines
We propose a gamut mapping method based on a physical model: the trajectory of a charged particle along electrostatic field lines induced by charges placed on the surface of the gamut. Since an electrostatic field is free of divergence, every out-of-gamut color is uniquely mapped onto a gamut surface point. The distribution of the charges on the surface can be used to influence the mapping.
In Océ's new Color Production System (CPS 700), colors are formed by adhesively collecting seven different toners. Consequently, mixed colors consist of toner particles beside each other and not on top of each other, giving the color gamut a concave shape. Our method yields smoother transitions between colors than any other method we have tried.
The paper will discuss the need for continuous gamut mappings, the field line method and its benefits for transitions between monocolors in the CPS 700.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
