摘要

The objective of this research is to produce output prints that are spectrally matched to original colors. The spectral characteristic curves of cyan, magenta, yellow and black inks have been obtained for 10%,25%, 40%, 50%, 75% and 100%.dot areas. The spectral curves of two color, three color and four color combinations are also obtained. From the curves, it has been seen that a single equation for all tonal variation if not sufficient to describe the color conversion In this study, a model having spectral hue error correction factors are proposed. It has been observed that the equation is dependent on tonal variation. The correction factors are different from low key to high key images. The factor dependent on tonal variation can be incorporated in the equation keeping other parameters same. The output print quality has been assessed in different printers. Experiments are made on Yule-Nielson modified Neugebauer model with different n for tonal variation. The suggested model offers better color matching with minimum E_(00).
