It is necessary to describe the gamut boundaries of the original and the reproduction properly for gamut mapping. It requires a thorough understanding of color reproduction gamut. Normally, the color values (CIELab) of different points are measured for describing the gamut boundary. For media gamut, it can be done by Kubelka-Munk equations and Neugebauer equation. In the present study, the gamut boundaries of the images are described considering color values of all pixels instead of measuring the CIELab values of sample points, which will minimize the approximation error. The out-of gamut colors are easily found in this way. It has been observed that the out-of-gamut color regions are not similar for different color zones. It has also been observed that the ratio of output gamut to input gamut are different for different images. Considering all these facts, an image-dependent gamut mapping is suggested in the present study.

  • 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.
