Configuration applied with half - tone colors free of moire effect

摘要

"Configuration applied with half - tone colors free of moire effect". The present invention relates to a configuration of halftone colour free of moire effect for items grouped together.Unlike conventional methods, the method produces periodic hexagon rosettes showed identical formats.These rosettes of hexagon samples have three fundamental space frequencies exactly equal to half the fundamental frequency of the three halftone screens.The production of halftone are genuinely free from moire effect.As all the fundamental and harmonic frequencies are multiples, and thus higher in frequency than the fundamental frequency of the rosette.The production of half - tone resulting from the employment of design of the illustrative rosette methodologically provided in this document,Are also resistant to erroneous typical registration between color separations commonly found in color systems.
