Dependence of Color Hue-shift on Ink and Toner Scattering Power
Abstract:Printed colors are the results of the optical interaction of colorant (ink or toner) and media. Colorant can be modeled as an optical media that possesses spectrally selective optical scattering power and absorption power. With both optical properties estimated, the optical behavior of colorant on media (or the printed colors) can be predicted theoretically. In this paper, a two-constant Kubelka-Munk model is used to characterize printing inks and toners in terms of their optical scattering and absorption power. Printed colors were then predicted by alternating the orders that inks and toners are placed on media. It was found that the order of ink and toner placement could produce significant hue-shifts depending on the corresponding scattering power. The Magnitude and direction of the shift were also verified with printing samples.

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.
