Color Appearance and Spatial Related Color Gamut Mapping
Abstract:This paper proposes an algorithm named Color Appearance and Spatial Related Color Gamut Mapping(CASRCGM).This algorithm is using the image Color Appearance Model (iCAM) as standard connection space. Color appearance attributes like lightness (J), chroma (C), and hue (h) as mapping variables are used for color gamut mapping. Confirmatory experiments of CASRCGM were based on a digital workflow with color inkjet printer. Eight digital originals were transformed from source image gamut to target printer's gamut. Control group was tested with CIE recommended Algorithms HPMinΔE and SGCK. After pairwise comparisons on monitors, psychophysical visual evaluation on images after mapping were carried out. The results indicated that the proposed Algorithm are better than those recommended by CIE in mapping accuracy and uniformity of color appearance.

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.
