The patent investigations of all known methods of photopolymer platemaking has been carried out. The investigation trend based on "The Method of Photopolymer Plate Production" according to №22445A Patent of Ukraine has been defined. The known theoretical research results of printing elements'formation in the body of photopolymer material has been analysed and the energetic relief - forming theory has been accepted as a basis. Inside this theory the analytic form for defining the integral migitation rate of isoenergetic circuit has been added, mathematic and programme software for its calculation have been worked out, its calculanions for line and dot-sizes have been made, the regression equation for obtaining the parameters of printing profile depending on material's optical density and printing elements of linear size has been concluded. Theoretical investigation of light-sensitivity parameter's dependence on the hight of printing elements taking into account the equality criterion of optical density of the original relief image has been carried out. The experimental research of relief-forming using the materials with wide range of light-sensitivity parameters, contrast and half-tone photomaterials, various spectrum light-emission sonrces have been fulfilled. In the result of investigiation the demands to photomaterials, light-sensitive material "Fotoplast VF40", "Fotoplast VF50", "Fotoplast VSh" used for making printing plates with different hight and depth of relief image have been defined. Due to shutdown of research finansing 2002.01.01 all research work has been terminated.56355635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
