Spot Color Matching Method Based on Preserved High Saturation for Inkjet Digital Proofing
The accurate reproduction of spot color is a difficult problem in inkjet digital proofing because of the properties of high saturation and out of the gamut of the spot color. A spot color matching method based on preserved high saturation is presented in this paper. The lightness is dealt with compression transform and modification, with the hue angle of the spot color unchanged. By this means, the precise reproduction of saturation of the spot color can be guaranteed to the maximum extent. When applying our method to the spot color matching process, the experiment result shows that, not only the property of high saturation is well preserved, but also the accuracy of spot color reproduction is improved.
