Modeling the Color of Multi-Colored Halftones

摘要: A mathematical model which provides the relationship between dot areas of a combination halftone patterns and color produced by such multi-colored is disclosed. Such has application in calibration digital systems, picture exchange, simulation “spot color” using process techniques. The new an extension Spectral Yule-Nielsen described this author at previous TAGA conference. It greater accuracy than Neugebauer model, either with or without correction. Experimental verification Demichel overlap presented. was found to be accurate for superimposed 30 degree orientation. acceptable level many applications. In experimental evaluation, predictions were sufficiently close measured so as indistinguishable human observer.
