Multi-color and artistic dithering

摘要

A multi-color dithering algorithm is proposed,which converts a barycentric combination of color intensities into a multi-color non overlapping surface coverage.Multi-color dithering is a generalization of standard b-level dithering.COmbiend with tetrahedral color separation,multi-color dithering makes it possible to print images made of a set of non-standard inks.In ocntrast to most previous color halftoning mehtods,multi-color dithering ensures by construction that the different selected basic colores are printed side by side.
