Multilevel Vector Error Diffusion with Solvent Control
Serge Cattarinussi, Ana Dimitrijevic · Conference on Colour in Graphics Imaging and Vision · 2008
We propose a new multilevel vector error diffusion method which introduces a control parameter S related to the physical amount of solvent (liquid) allowed for producing a given input color by combining dark (saturated) and light (unsaturated) ink separations. The solvent S appears as a fourth input variable to the error diffusion process where the quantizer is designed to choose the closest primitive in the CMYS space.
