Zorenko Y. The improvement of image reproduction technologies by the offset printing

Dissertation is devoted to the research of conformities to the law of interaction of technical and quality reproductions parameters of the system «original—imprint» on offset printing with hybrid technologies, design of reproduction stages for stabilization of technology process of tone reproduction. The regularities of the parameters influence and algorithms for halftone screening and color separation on the optical properties stability of reproduction in print run with variable specifications. A mathematical model of the reproduction process based on the parameters of the "original-imprint" for the prediction of reproduction properties and reliability assessment for it. A set of methods and means of hybrid technology to control the halftone and color at all stages of reproduction, which develops the technological basis for the stabilization of the optical density, contrast and color reproduction during printing. The results of theoretical and experimental research have been implemented in production.
